Derek finds Sarah at the cemetery where Kyle is buried and gives her shit for lying to him last week. John comes with a cell phone picture of a little girl, and says he knows where she is.
At school, Savannah is IMing with Cromartie. The teacher is not pleased and tells Weaver. Savannah tells Weaver that she was teaching John Henry a song, but refuses to teach Weaver. There's a very special lesson about the dangers of the Internet.
John Henry wonders if he has a brother that looks like him. He complains that the human brain can't download anywhere when people die. He wants to be able to know what his brother is thinking. Then he helps Savannah with her math homework and saves her from the Terminator security guy who has invaded Weaver's house. Such a multitasker, that Cromartie. Savannah runs into John's arms. Cameron actually gets to fight a terminator! But he escapes and shoots Derek in the head!!!! Cameron catches up with him and throws him off a big old hill. Then the Connor clan finds a dead Derek. Sarah coldly advises them all to keep moving. John looks horrified. For his part, John Henry watches on and just looks confused.
The LAPD have put out an Amber Alert on Savannah. Ellison tells the LAPD they'll find the kid. Cromartie wants to know why Ellison lied about Sarah being dead. He also shows Ellison the terminator that was at the house. Ellison and Sarah have a little face-to-face; she wants to meet in person with Weaver. Weaver tells Ellison that in the grand scheme of things, John Henry's survival is more important than Savannah's. LAPD guy is suspicious about Ellison's involvement with Derek's murder.
Meanwhile, Savannah explains to John about John Henry, and he figures out that he's Cromartie. Cameron wants to kill him real bad. Sarah says no one is going to be killed.
John Henry learns lots of things about lying. And he's confused about the whole Cain and Abel story and how that relates to him. Weaver tells him he's God. Knowledge is power.
The Connor family goes to the movies to wait for Ellison. He shows up and takes Savannah, while Sarah gets arrested by the police. John threatens to kill Ellison, and he and Cameron run out the back door. John Henry sings Savannah's Scottish song, while John watches the footage of his mom going into the police station. Derek gets buried in the same unmarked-type grave as his brother.
Previously: Sarah lied to Derek and Cameron and whisked John away to Charley's. Which was a monumentally bad idea, but then she got to shock someone in the head which was kind of cool. Cromartie's been reprogrammed and is now John Henry. Oh, and poor Charley is dead and gone.
We zoom in on a row of graves just marked by the year 1984. Sarah's looking out over them all wistfully. Derek walks up, and Sarah tells him that she doesn't know which one is Kyle's. Then he calls her out for lying to him about going to the desert last week and sending him and Cameron on a wild goose chase. She claims she only stopped to see Charley, and it wasn't planned, but he's dead now. John already gave Derek the 411, which is the only reason Derek was able to find her at this random cemetery. Derek gets that Sarah doesn't trust him, but basically says that his brother being dead should count for something. Nope. He's too secretive for her liking. They look like they are about to get into it, but John walks up and tells them they've got to go chasing after a little girl whose picture he found on one of the baddies from the lighthouse. No sense mourning over Charley or Kyle since he knows everyone dies for him. Ominous foreshadowing.
Savannah is in her classroom and supposedly learning new words, but instead she's IMing with Cromartie/John Henry. Cue parent-teacher conference with Weaver. Teacher goes on and on about the dangers of child molesters and generally pervy liars on the Internet. Weaver is none too pleased and asks Savannah what her deal is. Apparently, the creepy little girl decided that instead of learning a word like she was supposed to, she was going to teach John Henry a lullaby that her daddy used to sing to her. Weaver wants to learn the song, but Savannah tells her that she can't sing. Damn it. I was hoping to hear Shirley Manson sing. Alas. No singing, just a lecture about how people might not understand John Henry. He's got to be a secret.
John Henry is checking out his reflection and trying to figure out if his brother looks like him. Ellison says that his computer brother doesn't look like anything. He's a computer. John Henry wants to know if they share the same data and thoughts. Ellison thinks he's unique. True. Not everyone has a big cord coming out of their head. John Henry wants to know if they laugh alike, walk alike, at times even talk alike. John Henry then goes on to talk about how being a human would suck because the brain has nowhere to download. Hence computers are more awesome. Then he talks about the Bible and how heaven has a hardware problem. Too many souls, not enough microprocessors. He then tells Ellison he needs to get into his brother's brain, because he doesn't want to die again. What? I dunno. There's probably only one more episode left, so I'm not going to try to make sense of Cromartie/John Henry reading the Bible. Let's just give him some episodes of Battlestar Galactica and tell him they're real. That'll really blow his mind.
