Episode Quotes

Detective Lionel Fusco: You can't trust us, how are we supposed to trust you?
John Reese: Trust is complicated, Lionel. For example, I'm sitting in a police car with one cop who tried to murder me and another who spent six months trying to lock me up. So you'll forgive me if I take things one step at a time.
Caroline Turing: This must be what panic feels like...
John Reese: Here... have some chocolate.
Caroline Turing: Will they help to produce an adrenalin response?
John Reese: No... but they taste good.
Detective Joss Carter: You have a entire FBI task force looking for you... they think you're working for Elias.
John Reese: I'm often misunderstood...

Mistakes/Goofs

  • Goof (miscellaneous): There is a grammar error near the end of the show when the smart phone close-up of the "ANONYMOUS Email" page is shown. For about 2 seconds we see this page with some bullet points. One of the bullet points says: Find out if your friend is are real friend.
  • Goof (continuity error): When Finch has activated the program that blocks all unauthorized access to the cell phone towers it is stated that only one number is authorized. That number belongs to Finch. However minutes later we see Carter and Fusco both using their cell phones. While Fusco is calling Finch which could be authorized, Carter calls Reese who is not authorized. We have not seen the program being switched off in the intervening time.
