Jericho

Nitpick: Why not explode a portion of the eastern end of the bridge approach, effectively preventing the Ravenwood detachment from entering town? This would leave damage that could easily be repaired later without mechanized equipment. As Johnston Green wisely pointed out, the bridge might be needed as an evacuation route; not to mention the foodstuffs available from the farms on the other side of the bridge.

Nitpicks: When Emily enters the church at the end of the episode, most of the candles are fairly freshly lit--some looking like they've been lit within the last few minutes. This implies that someone else (the priest?) is there, and yet we see no one. It also seems highly unlikely that they would waste so many candles on an empty church when there's no supply readily available.

The Morse code message heard over the title is:
AOV SURPRISE
AOV stands for Area of Vulnerability.

Based on Dr. Dhuwalia's words, Las Vegas apparently still exists. He was living there until the bombs and joined the Red Cross to get out which brought him to Rogue River.

The boat underneath the bridge had California registration on it "CF".

At the end of this episode there are 11 known Ravenwood men who are still alive out of this dispatch.

RANGER
HANDBOOK

This is what the title of the World War 2 book read that Johnston gave to Jake which was from Jake's grandfather.

Emily Sullivan's name would be Emily Hammond if she married Roger, meaning Roger's last name is Hammond.

Jericho Geography: It is revealed in this episode that both Stanley's farm and Jonas's compound are located east of the town on the other side of the bridge, between Jericho and Rogue River. There is also mention of several other food-producing farms that lie on the other side as well.

Goof: About 12:50 into the episode, just after the boys talk about the mercenaries and before they get up off the floor, one of the dead soldiers is seen breathing.

When Gray Anderson and Jimmy (Bob Stephenson) are talking with Robert Hawkins and Allison Hawkins. Jimmy has in the first shot "25.20" a green jacket on, then no jacket in the next shot of him. Then again with the jacket on.

Jericho Geography: Sign outside the hospital in Rogue River reveals that that town is located in Fillmore County.

Nitpick: According to his driver's license, Eric's birthday is September 21, 1977. In the episode "Federal Response" we saw that Jake's birthday is January 21, 1977. This makes Eric exactly eight months younger than Jake. Even with a premature birth it is highly unlikely that the two brothers could have been born so closely together.

The markings on the houses in Rogue River are similar to those used by FEMA and other groups during the evacuation of New Orleans after the Hurricane Katrina Disaster.

When Jake and Randy are talking at the hospital, Jake says that he was working in Iraq for a security contractor, driving a truck back and forth to the Green Zone. If this is true, Jake was not in prison in his years away from Jericho but in Iraq.

During Gray Anderson and Jimmy's interrogation of the Hawkins family, they find an FBI badge and Robert convinces them that he is an undercover FBI agent. The Morse code heard over the title "ROB NOT FBI" convinces otherwise.

When Eric and Jake arrive at Rogue River, there is a clock stopped at exactly 9:02 because that was the time when the EMP was set off in episode 6 AKA "9:02".

According to his driver's license, Eric Green is 6'2", 190 lbs. His date of birth is 21 Sept 1977, and his address is 621 Granville Street.

Randy told Jake and Eric that FEMA set up a tent city a few miles north of Rogue River. This is where all of the evacuees of Rogue River were taken.
