Great season finale!

"Superb"
In tonight's episode, the season finale, we find someone assembling a bomb. The explosives are C-4, stuck together with an orange colored tape. The bomber is wearing a pair of black gloves. He solders together the bomb and inserts the blasting cap. It's unclear where exactly this is taking place and the identity of the bomber isn't revealed.
We cut to a group of New Yorkers who are having a Sunday block party, just as Lindsay and Det. Flack arrive. There's a deceased security guard inside of the apartment building. The man is ID'd as Darwin Judge. They got the call because he missed his scheduled check-in. Darwin has a single stab wound in his gut. Mac notices a blood trail leading up the set of stairs. Lindsay believes there may be some latent footprints so she heads back out to the truck to retrieve a piece of technology to retrieve the footprints, should they still be there. Mac and Det. Flack follow the blood drops and they lead to a door, so they enter it. The area is apparently a brokerage firm, so there's no one there at work today. They come to the end of the blood trail and see that the guard did put up a fight. Mac notices an overturned ladder and above it, a ceiling panel is not in the place it should be. He puts the ladder back up and takes a look in the ceiling and is surprised to find a bomb. Mac immediately hops off of the ladder and tells Flack to help alert everyone in the building, so Flack hits the fire alarm, sending everyone out. Flack calls the bomb into the PD and helps Mac by going door to door, getting people out. Outside, Lindsay receives a call from Mac, who tells her to get everyone away from the building because of the bomb. Lindsay immediately asks people to back away from the building, and the people do so. As the people who were evacuated exit the building, Lindsay tells them where to go as well. When they believe to have everyone out, they find a man who was wearing headphones and is confused about what's going on. Outside, Lindsay looks back at the building after getting people back, and there's then a large explosion, knocking out the glass windows and sending a shockwave throughout the immediate area, sending Lindsay and a few others flying.
After the credits, we find firefighters and EMTs treating people who have injured. Most of the people were injured because of the flying debris from the building. A few of them have headaches and hearing problems because of the sound of the blast. Eventually, the rest of the CSIs arrive, Danny, Stella, and Dr. Hawkes. Lindsay informs them of what happened and they immediately get to work. Lindsay's trying to call Mac, but his phone just rings, no one answers. Danny and Dr. Hawkes enter the area in which the original team was investigating the death of the security guard. They find Lindsay's CSI case and Mac's camera, as well as the dead security guard. They correctly conclude Flack and Mac went up the stairs, so they go up it as well.
Outside of the building, Stella has pretty much taken over control of the scene. She's cautious about sending in more people because they don't know how safe the structure is after the explosion. Just then, a woman walks up to Stella and identifies herself as Ellen Fielding from the Department of Homeland Security. She and Stella chat about the command posts and more ATF people will be there soon to examine the building for pieces of explosives. Lindsay walks by and tells Stella that the head of the building did a head-count, and there are at least eight people still inside. With Flack and Mac still inside, there are at least ten. Ellen finds the low bodycount as being out of the ordinary for terrorists, so Lindsay suggests that the building itself may have been the target, not those who lived and worked in the area.
Back inside, Danny is working with some of the search and rescue people. They're using a camera to search through some of the debris. As the camera gets pushed through the rubble, they come across a hand, but it's unclear who the person is.
Elsewhere in the building, Mac is coming to. He pushes some of the debris off of him and is slowly able to stand up. He calls out for Detective Don Flack, but doesn't get a response. After getting up, Mac looks for survivors and comes across the young man with the headphones. He appears to be just fine. Mac then sees Flack across the room. He's in very bad shape. Mac has a flashback of a similar situation when he was a young marine. As Mac checks out Flack's wounds, he realizes they're more severe than he thought. There's quite a hole in Flack's stomach, with a torn artery, sending blood everywhere. Mac has the young man help him by using a shoestring to clamp together the artery, hopefully helping Don live. Mac then asks the young man to grab something and bang on a wall to make some noise for search and rescue. Mac then uses some cloth to soak up some of the blood from Don's stomach.
Outside, Stella informs members of the FBI about separating the debris for analysis at the crime lab. She also notes that they need a sample of the explosive, likely from one of the inner walls.
Back inside, Mac is tending to Don, but Mac is still having flashbacks of the marine he lost many years ago. We then see a pair of flashlights. It's Danny and another individual. Danny asks if Mac is in there, so Mac speaks up and tells him that Don is injured.
At the crime lab, EMTs are checking out Mac, who while injured, is doing just fine compared to Don. Stella briefs him on the collapse of the above floor, which is why most of the people got hurt. We then learn the teams have been working on photographing the scene thoroughly, which will enable them to reconstruct the blast on a computer later on. As the EMT removes Mac's shirt, we see his old wound from his military service. An explosion left quite a scar on his left chest.
Back at the scene, Danny and the other teams are documenting everything. Danny then calls Lindsay and tells her he's going to send a series of photos to her. He sends a series of eleven photos from the crime scene, and we get to see each of them.
Back at the lab, tests on the wallpaper have given them the results on the type of explosive; it's C-4. This is a military grade of explosive. They also learned from Sid that the security guard was killed by someone with military precision, a stab wound to the aortic wall, causing massive bleeding. One of the feds mentions C-4 is usually marked in some way, which allow them to find the manufacturer. This is good news, as it may help narrow their investigation. Unfortunately, they haven't been able to reconstruct the bomb. All they have is the bag it was in and some wires. They are still missing the trigger.
Mac stops by the hospital Det. Don Flack is being treated in. Mac learns he can't see him until the surgery is complete. We quickly cut to the surgery scene, which is a little gruesome, but it's not too terrible. The surgeons remove several pieces of shrapnel/debris from Don's gut and chest. After the surgery, Mac is allowed in. He enters as a CSI, with his camera and takes a number of photographs of the various wounds. He then says, "I'm going to get you through this, Don."
Back at the crime lab, Mac watches the 3-dimensional bomb recreation. It shows the relation of the bomb's explosion to how walls collapsed and the final location of Mac, Don, and Smith. Unfortunately, they still haven't been able to find the trigger. Mac then suggests taking a look at the shrapnel from Don's body. Mac, Lindsay, and Dr. Hawkes examine the debris, and some of it appears to be plastic. It turns out to be the remains of a cell phone. The fact that it was so melted tells them that the cell phone was near the bomb at the time of the explosion. The only reason for it to be so close to the bomb is if the phone was the actual trigger. Mac then receives a phone call from the bomber. He says that the next "demonstration" will be at 16:00. Mac asks Dr. Hawkes to get a trace put on the phone in case the bomber calls again. Unfortunately, the team only has three hours to find and disable the other bomb.
Later at the crime lab, Lindsay and Danny disassemble the cell phone to extract the SIM card in hopes of getting its cal log. They're able to retrieve two numbers. On May 15th at 6:33 pm, there was a call from 1-212-555-1130 and on May 16th at 12:21 pm, there was a call from 1-212-555-1445. Danny searches for the owner of the last phone number and he gets a "Restricted Access" screen, with the phrase "Secured Gov. Network" on it, meaning someone in the government made the call.
At the scene, we learn that Ellen Fielding triggered the bomb. She doesn't seem to have done it on purpose. She responded to a message she received from her office and unwittingly triggered the bomb. Mac and Lindsay then learn that the agency uses a series of codes in their correspondences, and a laptop containing those codes was stolen recently.
Back at the lab, Mac receives a call from the bomber. It's from 1-212-555-5498. It's a text message, which says 10-23-1983. Mac knows that the message means something... it was the date of the Marine Barracks bombing in Beirut, which Mac was stationed at, at the time. The bomber sends the text message and lets the phone ring twice before hanging up. Mac and Stella aren't entirely sure why the bomber doesn't trigger the bomb himself, instead of involving others. Mac gets another call from the bomber and quickly enters the number into a Signal Detection program from Shore Atlantic and gets a "no signal" notice. It happens every time. The bomber turns off the phone, leaving no signal. What the bomber doesn't know is that someone can remotely turn on the phone, so Mac does it and comes up with a result, Chelsea University. As Stella and Mac are about to leave the building, Mac receives another call. He asks Stella to put the trace on his phone, and she quickly does so. Mac notices the number isn't from the cell phone, it's from a pay phone this time. He answers the phone and the bomber congratulates him on figuring out how to remotely turn on the cell phone. When questioned, the bomber tells Mac that he's not his target, just a part of his demonstration.
Mac, Danny, and a few feds sweep a library for a bomb. A number of threats have been called in during the past few weeks, and they suspect it may be the next location. Mac finds a pay phone in the library, and a bomb is sitting on it. Mac tells the feds to get everyone behind the barrier.
We quickly cut to Mac and Danny working on the bomb. They're wearing special suits for it, obviously. Danny mentions the bomb squad isn't too happy about the two of them doing this, but Mac assures Danny that they didn't get to dismantle the other one to learn the bomber's signature, so it really doesn't matter. Mac cautiously cuts some of the orange tape and then cuts the yellow and green wire, effectively dismantling the bomb, giving them a blasting cap/detonator to examine. The phone rings, and it's the bomber again. Mac tells him he's too late to detonate the device, but the bomber says "you're doing what I want."
Back at the lab, the CSI team is processing the cell phone, the tape, the bag, and all of the pieces to the bomb. Stella then finds a hair and Mac asks her to run the number of the detonator. It has the ID # of 2010336. The search turns up "Fort Wadsworth National Guard." Stella wonders if the bomber could actually be in the National Guard.
In the hallway, Jane Parsons tells Mac that Det. Don Flack was moved to a recovery room, so he seems to be doing a little better, which is great news. Mac changes the subject to focus on the hair Stella recovered. Jane wasn't able to find any DNA, but she found a drug used to treat people with mental problems. It seems our bomber has stopped taking his schizophrenia medication recently. Lindsay and Dr. Hawkes stop into Mac's office and tell him that they just spoke to the National Guard Armory and have learned that they hired a private contractor to dispose of some out-dated explosives and when they arrived to collect it, someone else had already done so. The government laptop likely gave the bomber the information he needed to gain access to the armory. The logo from the van used in the crime has been located at an abandoned house.
Mac and Stella arrive at the house and find the white van in the garage. They process the garage and find photographs of potential targets. They also find a number of identity tags (NTSB, Secret Service, etc), the stolen laptop, Mac's shield (badge) he lost during the explosion, a place on the wall where an M-16 would be kept, and 20 pounds of C-4. On the laptop, Stella finds a lot of information about Mac. The bomber did his research on him, gaining access to a lot of military records. The two CSIs search through a few boxes on a shelf and find that the man failed getting into the military, failing the psych evaluation. Stella then finds a series of letters written to the government, warning them about how vulnerable the country is. All of the letters had a different author, however. Mac then receives a call from the bomber. He tells Mac to be in town for a show and to bring reinforcements because Mac will need all the help he can get.
Back at the lab, Stella and Mac walk in and Dean Lessing, one of the feds, left blue footprints on the floor when he left the room. He was stationed to the outside of the building. Mac knows that he was inside, because the blue powder is ink toner from one of the copy machines, which fell from a higher floor. Mac then recalls what Lessing said as he was leaving the room, something about one of the groups needing all the help they can get. Ellen Fielding then walks in and asks Mac and Stella if they have any leads. She's shocked when he says Lessing has something to do with it. Lessing just took a car uptown, so Mac gets on the phone and asks Det. Scagnetti about other area threats. One of the other targets is just a few blocks away, so Mac tells him to bring backup to the location, a theatre.
The CSIs and feds arrive at the Goodmanson Theatre. Outside, Ellen Fielding tells Mac that she doesn't mind if he leads the operation, but she wants to take care of Lessing. Mac then briefs the law enforcement officers of the danger of Lessing, who is believed to have explosives and an automatic weapon, the M-16 that was missing from the wall of the abandoned home. The police then enter the theatre and are quickly ambushed by someone with an automatic weapon. He uses the lights to see the police on the stage, while at the same time, partially blinding them. Sella and Ellen make their way through the theatre and Ellen is then confronted by Lessing. He orders her to put down her weapon and she does so. He tells her that "we are not ready." Mac then comes in with his gun pointed at Lessing, asking him to drop his weapon. He tells him his point has been made, that his demonstration is over. Lessing says that the country is still very vulnerable to an attack. He then refers to Mac as 'Sir' and mentions something about serving his country. Mac then puts his weapon down and tells Lessing to secure his weapon. Mac is a superior officer and speaks to Lessing as though Lessing were a private. Eventually, Lessing secures his weapon, per Mac's orders. Mac walks over to him and takes the M-16 from him, and Lessing says "Lance Corporal Lessing reporting for assignment, Sir!" Feeling as though his mission was accomplished, Lessing agrees to the police escorting him out.
At the hospital, Mac and Stella talk about Lessing and the fact that he didn't want to kill anyone, just to show people the country is still vulnerable to attack. Mac then mentions that this one took him back to a marine who died in front of him, Corporal Stan Whitney, marine sentry at the Beirut airport. Although Mac was injured badly in the attack, he lost Cpl. Whitney in his own arms. Dr. Hawkes, Danny, and Lindsay join them in the hallway. It seems Det. Flack is improving. While Stella leaves to get some coffee, Dr. Hawkes leaves to talk to Flack's neurologist to find out when the next CAT scan is. Danny then offers to give Lindsay a ride home, and they leave.
Later that evening, Mac tells Stella that he's glad she stayed. To which, Stella responds, "that's what we do; we take care of each other."
A bit later, Mac goes in to Flack's room to see him. Flack seems to be still out, but Mac tries to talk to him. In an emotional scene, Mac asks him to squeeze his hand if he can hear him. After a while, Flack gives Mac's hand a strong squeeze and then relaxes a little. He continues to hold Flack's hand as the show ends and the credits roll.
I really enjoyed tonight's episode. As far as season finales go, this had all of the action, danger, and emotion you would expect. It's terrible to see Flack so injured, but this is a storyline which could last several episodes in season three. I wonder if something will happen between Danny and Lindsay... Danny's attracted to her and she doesn't seem to mind him at the same time. We'll just have to wait and see...
