Elsewhere, Hobson is alerted by an orderly that the electrodes in Room 22 aren't picking up any data. "Thank you for telling me," says Hobson, rather robotically. That's right. She's acted completely human up until now, but suddenly she's speaking flatly and walking the terminator purposeful walk.
So John's finally deleted Sarah's profile, but now they've got another problem. Someone's beeping on the keypad outside the room. Hey, Sarah, climb up to the ceiling this time!
So Hobson comes in, and she sees just Sarah standing there. Sarah offers a "sleepwalking" excuse, and Hobson says, "Through a locked door?" Sarah's all "sorry" and then stares over at John, who's TRYING to hide behind some computers. She says she'll go back to her room. "Did you know that when a human falls in love the same areas of the brain light up as when a human is intoxicated?" says Hobson. Yeah, here comes the "human" talk. Hobson also says they don't know why humans dream. "Humans like you?" asks Sarah, that cock-eyed optimist. Hobson just smiles. "You drugged me," says Sarah. Hobson says she's experiencing sleep paralysis: "You'll want to move, but you can't." Then she picks Sarah up and throws her against the wall. Sarah falls to the floor and Hobson gets on top and tells Sarah that, believe it or not, her body is actually protecting her right now. She grabs Sarah by the throat, and says Sarah was talking to her boy just now, and orders Sarah to call him. She stands up. "I'd die first," says Sarah, and Hobson knocks her across the mouth, knocking out a couple of teeth. "I'm sure you'd like that, to die. It's never that easy," says Hobson, just like Winston did in the van. She picks up a big computer and lifts it above her head to throw at Sarah, but is shot three times in the chest by John. She falls backward. Sarah takes his gun, and goes and stands right over Hobson's body, because Sarah's been taking notes while watching Friday the 13th movies. Hobson's eyes open, and she grabs the gun and blows John away, and then shoots Sarah right between the eyes. She falls to the floor, dead.
So if you die in your dreams, do you die in real life? Sarah's in the back of the van, handcuffed, and Winston's outside on the phone, saying Sarah's son is the one they want, and they'll give him a little more time to show up. Sarah frantically works at her handcuffs, and ... oh, my god, she's biting into her wrist. She's drawing blood! Her mouth is ringed with her own blood! Then she braces her legs behind her cuffs, and pushes, and -- oh, that crunch sound made my stomach turn.
