There's a stunned silence from Marty when he hears Shin laughing. Is he hearing it wrong? Maybe he's hurt so bad, he's laughing. Because there's no way they can both be intact after a stunt like this.

But Marty smiles. A smile brings a chuckle, which then summons a laughing fit so bad, his stomach starts to hurt. Being in a band was fun and all, but it was stuff like jumping off of a bike that seemed to make life...real. As stupid as that would sound if he ever told anybody about it.

When he can finally breathe, Marty's gotta ask. "Where, where the hell's the bike?"
