Trivia: The glyph code for this episode is FUTURE.
Dr. Anderson: You have to admit, it's a little weird, what's happened to you.
Olivia: I work in Fringe Division. Weird is-is a matter of degrees.
Walter: I--I like porcupines. Shows that God has a sense of humor.
Lincoln: Huh. You remember you said eventually all of this would stop getting strange? In case you were wondering, it still hasn't.
Walter: This tattoo... is cuneiform. I'm not sure of the significance of the symbol, but I'm fairly certain that it's Sumerian. Not my favorite ancient language. I prefer Yiddish. Belly's father taught it to me. He was a charming man.
Olivia: It has to do with cuneiform.
Markham: Sumerian, Hittite, or Akkadian?
Markham: I know. I'm a very, very impressive man.
Olivia: And I'm still taken.
Markham: Can't blame a guy for trying.
Walter: I can't cure the intermediate stage. Once the virus fully matures, I should be able to counteract it.
Walter: Most likely. 80%
Lincoln: And if I'm part of the other 20%?
Walter: Let's take it one step at a time.
Lincoln: Do I really have to drink that?
Walter: Only if you want to live. A blend of wheat grass, penicillin, some mild laxatives, and I put in some mint to kill the aftertaste.
Lincoln: It didn't work.
Broyles: (to Olivia) I've been on the phone to the top floor for the past hour. What we've decided is this... if you're 60% of the Olivia I knew, you're still better than 90% of the agents I've ever worked with. And a Fringe division with Olivia Dunham is better than one without her.
