The Connors are finally moving out of the Compound and heading for a safe house, only Sarah's taking John on a detour without Cameron and Derek because she doesn't trust either of them anymore. They head to a house on the water, by a lighthouse, which is where Charley's hanging out, and doing supportive things like rigging the place with Semtex in case everyone needs to make a quick getaway by boat. Sarah wants Charley to feel her breast, but not in that way (especially since he's still grieving the loss of his wife). She's found a lump, and she's worried that the cancer she was originally supposed to die of in 2005 has finally caught up with her.
So she goes to the doctor, where she founds out that the lump isn't a tumor but a cystic mass that's gathered around a little piece of metal. She figures out it’s a tiny transmitter, and Sarah uses a defibrillator to zap it (and herself) out of commission, but the shadowy dudes are already converging on her location.
Cameron and Derek are also in trouble, both from each other -- Derek gets upset when Cameron breaks the news to him that Jesse was pregnant with his child aboard the Jimmy Carter and lost it -- and from the shadowy bad guys. They manage to kidnap Derek, but Cameron tracks them down and rescues him. Sarah defibrillates a bad guy's head and escapes and heads back to the lighthouse, where she arrives after a firefight and explosion. John's nowhere to be found. Charley's there, though. Only he's floating face-up in the water.
Meanwhile, John Henry's making real progress. He goes from playing with Lego to Savannah to being the target of an artificial intelligence trying to get inside him with a worm to control him remotely. He recognizes some of the computer code within the other intelligence, since he's got the same stuff. This other intelligence is more advanced, but it's like they're brothers, and their father is Miles Dyson.
