Back in the van, Winston is saying that most people don't know anything about torture, which must be a heartening thing for Sarah to hear. "It's not the pain that causes people to talk. It's the talking that causes people pain," he says. No, I'm pretty sure it's the exact opposite, Winston, but thanks for your faux-deep observation. Unless you mean, "It's other people talking that causes people pain," then I completely get it. This episode is Exhibit A. He wants her to tell him a story, and I REALLY WISH SOMEONE WOULD TELL A STORY, and she counters by telling him that he told her a story once, back at the warehouse, about his son. "That's when you let me go," says Winston, who thinks it's funny now, because she doesn't seem like the sentimental type.
"Your story, not mine," Sarah reminds him. "Yeah, but you believed it," says Winston. He crawls right up next to her. "Because you have a child," he says figuring things out. Things start to click for him. "My story is your story," he tells her, and that's why she gave it back to him when he asked her for one. "You have a son. He's your accomplice," says Winston. He reaches to touch her face, and she recoils, but doesn't say anything. "See? That wasn't so hard," he says, sitting back, pleased with himself.
After the commercial break, Sarah, in the sleep clinic, waits as Dr. Hobson leaves her room, and then pulls down her robe off her shoulder to see the red welt left from the injection.
Back in the van, Winston is still talking about Sarah's son. "He's just a boy," says Sarah. "A boy you'd die to protect," he says. Sarah says any mother would. Any mother would die to defend John Connor? I don't think so! "You'd be surprised," says Winston, who then goes on to talk about how the enemy is like a weed: you leave any part of it underground, it will pop back up where you least expect it, so you have kill the root. "Or in this case..." the head vampire? "... the seed." Sarah says her son isn't alone, so Winston won't get anywhere near him. Winston says he won't have to, because her son will come to her. Sarah says her son is too smart for that, so I guess she must have some other son that we don't know about. Winston intends to make Sarah call her son, and to make his point, he starts choking her, although I've always found that positive reinforcement is far better for motivation than choking someone.
Then he stops. "We don't need to talk anymore," he says. Is that a promise? Sarah vows not to call John, saying she'll die first, and Winston's all, oh, you'd like that.
