I.

[The entire gang is enjoying popcorn and a movie at Fred's]
GoGo: So, Hiro, Baymax was sending me some upgrade suggestions to my phone when something interesting came up.
Hiro [stuffing his gullet with buttery goodness, muffling his words]: Oh, yuh? Wut's thawt?
GoGo [pleasantly]: An essay, entitled: Why My Friends Make Good Body Guards. [Hiro spits out popcorn] A paper by Hiro Hamada.
[Everyone looks unhappily towards Hiro... his seat is empty]
Wasabi: Hey... WHERE'D HE GO?
[Hiro takes cover behind a big bookcase]
A man's voice: You running from something, son?
Hiro: Yeah... uh, no... I-, [He looks up and it's Stan Lee]
The man smiles at his inability to speak: Follow me. [He leads Hiro down the hall to a family portrait and pushes it back] Go on, step inside.
[Hiro obeys and observes a legendary hero team]
Stan Lee: They were the *best* friends I ever had.
Hiro: And you never hid behind them for protection? Cause you were selfless and always put your life on the line.
Stan Lee: Who, me?! Heck no! I hid behind them all the time. I was a coward! One heck of a strategist and thinker though. That's why they kept me around.
Hiro smiles: So you *don't* have to be strong to be a hero.
Stan Lee smiles back: Nope, but in your case it might help to be.
[His team is waiting for an explanation]
Hiro: I... uh...
[They hand him a broom and a dust pan]
Baymax: I tried to explain the fragile nature of your body.
Wasabi: Dude, why didn't you just tell us you were scared?
Hiro: I'm not scared.
GoGo: You're also cleaning up the theater.
Fred: And then, Hiro's WARRIOR TRAINING BEGINS!
Honey, smiling: Maybe some normal high school-esque gym courses to start.
Hiro: Don't I get a say in this?
Team: No.
