Cameron's brown eyes flash blue as they're read by a retinal scanner. The door opens, and she opens it for Derek. Mouth agape, he walks into an empty room. Well, this room is empty. But a window looks out into a room with several jet engines in a ring around a crackling ball of energy.
As Derek takes this in, a decidedly fifteen-year-old-looking John comes up behind him. "Derek," he says. Derek turns, and...
...we're snapped back into the present day, with John telling Derek everything's going to be all right. And I think Derek is still laid out on the kitchen table. It might have been nice if Charley had helped move him to a bed. "What is all this?" asks Derek.
And right back to 2027, where Derek and his men survey the battle-scarred landscape. Timms says, "So this thing, it works?" "He said it does. I don't know how he knows, but he said so," says Derek. The plan is for them to go back 20 years. The other guys are skeptical about going back to set up a safehouse and then hang around for 20 years, waiting for orders. And what about Kyle? "All that and not a word about Kyle?" "We can save Kyle. We can save everybody. We can fix all the mistakes," says Derek. Timms asks how they're supposed to do that. Derek doesn't answer, but he exchanges looks with Andy.
The crackling ball of energy brings four more naked bodies into L.A.: Derek, Timms, Sumner, and Sayles. They gawk at their surroundings, at the towering buildings and sky free of Hunter-Killers. They should probably try to put some clothes on, but this being L.A., if anybody sees them, it'll just be, "Oh, look. It's the Red Hot Chili Peppers."
John's sitting up with Derek, telling him the story of one Kyle Reese, who came across time to protect him. "He died fighting the machines. He was a soldier, and he was ..." John struggles. His mom comes in, which doesn't help matters. "...he was a hero," he finishes. Derek smiles, and closes his eyes.
Sarah voiceovers again, recounting when Kyle told her that the machine is out there, and can't be reasoned with. We flash back to a young Andy Goode, alive in his hotel room at the chess tournament. The door bursts open. It's Derek. He raises his gun, and fires. He leaves, Andy Goode dead on the floor behind him. Which would mean that Wisher is now not there in 2027, which means he wouldn't have been sent back, which means...aw, screw it. None of it means anything.
