So they go to see John Henry, who admits to having seen Savannah: "She wanted to play a game." So where is she? She's hiding, says John Henry. Ellison orders John Henry to tell them where she is. "That's not how the game works," says John Henry, scoldingly, and then explains that if they guess what he's thinking, he'll give them a clue. Ellison tries again to get John Henry to tell them where Savannah is, but John Henry ignores this, closes his eyes and says, "I'm thinking of a country." Ellison's all, huh? And Henry looks to Weaver, who RATHER SUSPICIOUSLY is ENJOYING this, and she wants to play the game, and John Henry smiles, and Ellison snaps that he's not going to bargain with a computer. "If I'm not mistaken, Mr. Ellison, we've got no choice," says Weaver, who really ought to think about looking a little less excited about this and more concerned for her daughter.

Elsewhere, Derek is bandaging up Jesse's knuckles and chiding her for punching the guy in the mouth, because one time when he and Kyle were kids they saw two "tunnel trolls" fight over a can of stewed tomatoes. Ew! Anyway, the loser lost three teeth and the winner got the tomatoes and also a blood infection and died a week later. That's why he's giving her antibiotics too. Well, that and the syphilis.

Derek's cellphone rings, and he's all beep-boop and is surprised by what he's being told, and then says, "Damn," and then, "John OK?" He tells Sarah, presumably, to hold tight, that he's on his way.

He hangs up and tells Jesse that John's girlfriend is dead. Jesse somehow manages not to blurt out "I totally didn't do it." Derek tells her "the cyborg" did it. Jesse asks if he knows that for sure. "Who else could it be?" he asks, because nobody ever gets murdered. She asks what he's going to do about it: "Because you can't kill her, Derek," she says, really surprising him. "He has to make that decision on his own," she continues. Derek stares at her thoughtfully for a moment. "You've really thought this through," he says. She says no, but she does think about it: "Just like you do."

So back on the sub now, in the engine room, Jesse gets a report of more depth charges but no damage. "They want us to make a mistake. Reveal our position," says the terminator captain, played by the guy who played Cutty on The Wire. The newest trusty shellback, Garvin, gets on the sonar and has a look at all the blips. "We gotta Kraken," says Garvin. Jesse asks if he's sure, and then tells him to feed the sonar picture to tactical. She has a look at the diagram on some kind of display. "You're a big fella, aren't ya. And very far from home," she says. Then she studies the sonar map again. "That can't be right. Where are we?" she says, mostly to herself. Meanwhile, Queeg asks for a torpedo report. They've only got three. "Ready tube one, hold for my order." he says.
