Hiro-from-the-past meets Hiro-from-the-future
Past-Hiro: Hey! You're angsty!
Future-Hiro: Yes. Yes, I am. Probably because my job is to get shot right after anyone asks me a question.
Past-Hiro: How do I use my powers?
Future-Hiro: What did I just say?
Enter Evil-Parkman
Evil-Parkman: I'm the director of Homeland Security! My job is to shoot Future-Hiro, a lot!
Future-Hiro runs for it, Parkman arrests Past-Hiro
Evil-Parkman: You'll do.
Cut to Future-Hiro and Ando in Texas
Ando: Why am I just "Ando", not "Past-Ando"?
Future-Hiro: Would you people quit doing that!
Evil-Parkman bursts in and tasers Future-Hiro
Evil-Parkman: WTF? There are two?
Enter Über-Peter
Über-Peter: I have über healing powers, and a giant scar on my face! How does that work?
Über-Peter teleports in, saves Hiro and Ando
Evil-Parkman, to other cop: What? I shot him, didn't I?
Cut to President-Evil-Nathan talking to Suresh
President-Evil-Nathan: Yeah, I think we should kill every other character on the show.
Suresh: I have moral outrage!
Evil-Parkman: There are two Hiros. I have one, should I shoot him?
President-Evil-Nathan: No, Suresh can shoot him.
Evil-Parkman: Aw, man...
Suresh: I still have moral outrage! But I'll do it.
Cut to Suresh about to kill Past-Hiro
Suresh: Hey, gullible Haitian guy, please come over here and be distracted while I kill this guy? Whups, syringe in your neck, got you there.
Past-Hiro: Hey, you're not evil after all!
Future-Hiro and Über-Peter teleport in
Past-Hiro: Hey Future-Hiro, how do I teleport like you?
Future-Hiro: Easy, you just gotta-
Evil-Parkman beats down door and shoots Future-Hiro
Past-Hiro: Crud.
Past-Hiro teleports randomly, gets lucky, ends up back in the past. Happy ending!
