During the scene in which Olivia finds an engagement ring in the container with John's personal effects, there is a second metallic object visible inside the ring box. After the cut, the smaller object is absent.
Trivia: The glyph for this episode is "SURGG," possibly meant to be "SURGE."
It seems unusual as well as unlikely that any relevant security cameras that might have shown Joe Meegar on tape were wiped by the electronic pulse (including those outside the elevator that might have shown him entering) but the weight sensors on the elevator itself were undamaged so that Olivia could determine the weight discrepancy.
Trivia: During the scene in which they watch the news report a coffee cup has the word "INtREPUS" written across it. This word is a clue toward the next episode "The Cure."
Trivia: The Observer can be seen emerging from the elevator and putting on his hat as Joe walks past.
Peter: Visiting hours. Everyone put on their best straitjacket.
Olivia: So… what is this? Walter: This is the sort of work I was born for. Peter: You were hoping for something more specific, maybe?
Olivia: Walter, you're not going to accidentally fry one of those pigeons? Walter: Stranger things have happened. Peter: That's his motto.
Peter: So we're putting GPS chips on carrier pigeons to find a man who can control electricity. I have you to thank for that, don't I? Olivia: Yeah, that's me.
Astrid: Are you sure this is going to work? Walter: Of course not.
Peter: Seriously, if this works… Olivia: You're going to have some more faith in your father? Peter: No.
