Hiro and Ando head back into the museum to put the sword back as Simone leads Nathan into Isaac's studio. She's saying something about how Isaac was obsessed with the idea that the world was going to end via a bomb exploding in New York. Nathan notices the apocalypto-art on the floor for, like, the first time, and comments on it. Simone says that Isaac left a few weeks ago and that someone came and took his paintings, but then she looks around and sees that his paintings have all been returned. And, for that matter, so has Isaac. He appears across the room, toweling off his wet hair. And I would just like to say for the record that I for one am extremely thankful to whoever it was who decided that Isaac should enter this scene shirtless. Whoever you are, I think I love you.
Simone's stunned that Isaac is not only back, but that he appears to be clean and sober. And hot. He kisses her on the cheek and they share a moment and Nathan's all, yeah, I think I'm just gonna, uh, go over here and stare at some paint for a minute. Heh. Isaac tells Simone that he was in a clinic and woke up in Texas, clean as a whistle. He says that he can paint without the drugs. Simone's glad for him. "I'm only alive because of you, Simone," he says. "I still love you." Aw. Simone looks affected by his declaration, but Nathan interrupts the moment by mentioning a painting that he's looking at. It's the Exploding Man painting that Isaac painted while in "rehab". "How did you know about this?" asks Nathan. "Did you talk to my brother Peter?" Isaac says he painted what he saw, and Nathan informs him that Peter's last words before he collapsed were that he was the cause of the explosion. "Look, I may not get everything," says Nathan. "And that's fine. But this... I mean, this... these things can't be connected. The world doesn't work like this." At that precise moment, a hearty "Mystery Sock!" is heard from the studio entrance. "Bad news," says Hiro, entering the studio. "Sword not there! It was replica. Original owned by man named Linderman." Ando throws a bemused wave at everyone as Nathan peeks out from behind a painting. "Did he say 'Linderman'?" Nathan sees Hiro, Hiro sees Nathan, and suddenly, Hiro shouts, "FLYING MAN!" Nathan looks like, oh, shit. Heeeeeee.
