The title "Why Is This Night Any Different?" alludes to one of highlights of the Passover seder, which was a scene at the beginning of the episode.
Somewhere around 25th minute of the episode, when Carrie is getting into the car with the baby, this is a completely different car that the one she is driving in the next scene.
While Nick is asking the Imam for sanctuary in the mosque, the same two guys walk past Esme, from the same direction, twice.
During the discussions among the CIA Saul mentions about the Mumbai attack. The Mumbai attack he is referring to is the 26/11 attack carried out by terrorists on Taj Hotel in Mumbai. It took place in the year 2008 and involved many civilian casualties.
In the scene where Quinn delivers coffee to the team, the brand of Coffee is Tim Hortons. Tim Hortons is Canada's largest fast food service with over 3000 stores nationwide.

As of 1 July 2012, Tim Hortons has 4,071 restaurants, including 3,326 in Canada and 734 in the United States.
Brody likes to drink beer and go to bars. If he's really a devout Muslim he wouldn't be drinking!
In real-life, Brody's phone would have been confiscated before he could enter the situation room.
Goof: At 23:09 you can see the shadow of the camera operator on the door.
Tom Walker uses a self-storage unit to engage in clandestine activity.
Goof: The rank insignia on Brody's Blue Dress uniform are still those of a Sergeant instead of a Gunnery Sergeant.
As Saul exits the room for his polygraph, he passes a clock on the wall that shows that the time is 19:20 (7:20 PM) in Langley. It also shows that the Zulu (UTC) time is 25:20--an invalid time, since there are only 24 hours in a day. It also shows a third time zone being 29:20, also an invalid time.
Assuming that the 25:20 time is intended to be 01:20 (subtracting 24 hours from the 25:20), it would still be incorrect, since Zulu (UTC) time is at most five hours ahead of the time in Langley, VA, not six.
Though the show is set in Washington, DC, when Saul picks up Mira at the airport the sign in the background shows it to be the Charlotte-Douglas International Airport in North Carolina.
Saul recites a Kadish for Afsal, which is the jewish prayer for the dead.
Goof: He sings the Marine Corps Hymn wrong in this episode. When he is kneeling over the grave, he says: "First to fight for right and country" and the correct line is: "First to fight for right and freedom".
Brody recites his prayer by mouth. However, a Muslim does not need to speak the verses if he is praying alone; reciting them at heart or soundlessly is enough.
