Jack: I didn't expect you'd have the guts to contact me.
Will: Oh, well, I'll assume that's a compliment.
Weiss: Mike, I'm not going to trivialize your relationship with her by calling it a crush--
Vaughn: A crush?
Weiss: But whatever it is, it's starting to affect me and if that sounds selfish to you, I was hoping to retire fully vested. (pause) I know you genuinely care for her. I do, too. But there is a line that we have been sworn not to cross. We're about a mile past that.
Sloane: (to Sydney) It was your duty to report Emily to security section. You didn't. And that's more than I did for you.
Sodium pentothal, a.k.a. the "Truth Serum," is commonly used to extract information form prisoners in this kind of shows.

First synthesized in 1935, the proper name for the drug is thiopental sodium. A yellow water-soluble crystal, it is classified as an ultra-short acting barbiturate, a type of drug that depresses the central nervous system, slowing the heart rate and lowering blood pressure; in other words, it's a sedative. Widely used in medicine as an anesthetic during surgery, it is injected into the patient to produce rapid unconsciousness. Sodium Pentothal received the nickname "Truth Serum" because its effects, guided by the psychiatrist in therapy sessions, caused the patient to become very communicative, verbalizing thoughts easily without inhibition.
