Smallville

Martha holds the Key and shot moves to focus on the keyhole in ship 0:31, yet when she looks back over to the ship after Clark left, the ship is turned around, and the hole is nowhere near visible 0:56.

At 19:34 Helen removes the rubber strap from Clark's arm, but seconds later it is back on his arm and she removes it again.

When Jonathan breaks into the compound, his truck is left outside of the compound and was easily accessible during the escape, which means it should have been noticable. Wouldn't a security guard notice an unidentified truck parked right outside of a high security area?

When Jonathan is breaking into the DCA compound, the fence that he "cuts" isn't cut at all. It's just two separated fences. The only cut parts of the fence are the cuts we see him make as well as one cut below.

When Jonathan is breaking into the DCA compound, he's holding the fence shut as the security guard is passing by. It should be pretty hard not to notice an irregularity in the fence pattern, especially when you're a trained security guard.

When the DCA are heading to the Kents' farm, they are heading the same way that Clark and Pete are driving to get the ship away from the farm.

When Jonathan breaks into the military compound, how did Clark get there in that short a time, seeing as Jonathan drove and Clark is without his superpowers? Furthermore, if he was so ill he needed Jonathan's help to stay up and escape from the compound, how did he get into the compound and into the building unnoticed?

Clark tells the DCA that Martha has been in the storm cellar instead of keeping quiet and avoiding another detailed search.

Why was Clark waiting by Nell's house? Lana doesn't live there anymore, since she moved in with Chloe's family.

In the beginning, when Martha coughs and drops the pitcher breaking it into a sharp barb in the ground. She faints and is seen to be falling into it, but Clark catches her. When we see the long shot, the broken pitcher isn't there.

Clark's hair changes several times. In the beginning, when he sees his mom in the cellar, his bangs are straight, and parted to the side, like the way they were in the beginning of the series. Then, when he's in the kitchen, his bangs are how they usually are, curly and across his forehead. They continue to look like that at the hospital. When he races home to get the ship in the cellar, he pulls the sheet off of the ship and once again his bangs are straighter and parted to the side. Then, when he's driving with Pete, his bangs are curly and across his face.

Lex and Dr. Trenton do a really good job being subtle. They chose to exchange private information in a parking lot, in cars with non-tinted windows, and where people are passing by them and can see their faces.

So it doesn't seem like the Kents are really in the clear. The DCA has their red truck (and if Pete claims its stolen, that'll be on his record as a criminal offense), they know the octagonal key is missing, and they know the Kents used to have it. Is the DCA just going to ignore all of this, pack up, and leave? They may not have a purely legal case, but they appear to have enough to warrant investigation. Furthermore, the DCA had two vehicles as well as a helicopter following Pete, telling him to stop, which he doesn't do until he can't proceed any further. Shouldn't this lead to further speculation?

Clark has a zit on his chin. He has invulnerable skin - how can he get little dirt particles in his pores?

Inexplicably, Pete has somehow managed to pay for yet another new vehicle in this episode.

So the DCA has a base near Smallville? Note that the storage area has DCA stencilled on its windows so it looks to be more than just a temporary installation at an existing military base.

Lex gives Dr. Helen Bryce a master key to the manor. We've seen in the past that anyone (including Helen herself) can easily get into the mansion without a key with no one being the wiser - heck, using it would just slow her down.
