Kent Farm. Clark, who has changed into a blue T-shirt, is still trying to convince the Legion that he's beaten Brainiac. They tell Clark that history has marked this day as the day when Clark defeats the 'bot. Garth says he flunked history and even he knows the date. Clark notices a wedding program showing Chloe and Jimmy's photo. It gets his brain gears whirring. Irma notices a disturbance in the Jello-O-like brain force. She asks why Clark thinks Chloe has something to do with Brainiac. "You think she's the host," Rokk guesses. Yes. The one with the most. Clark walks dramatically to the door, saying he'll take care of this and that they can go back to the future. Sing the Huey Lewis song for all he cares. Rokk says that if Brainiac isn't defeated, they won't have a future to go back to. Wouldn't you already have disappeared by now, having never existed? Chew on that, future guy. Rokk points to the crystal as the problem; Clark was supposed to use it to beat Brainiac, but now it's broken. Clark thinks there must be another way. Garth says the crystal is the only way to do it without killing the host. Rokk informs Clark that he's going to have to kill the host. Imra asks, "Who's Chloe Sullivan?" Clark doesn't want to answer that.
