'Puberty' was Baymax's diagnosis when he woke up. Yeah. I'm well aware on that front.

[It's difficult for any normal teen. Let alone one as smart as Hiro, growing up going to school with children much older than he was, or suffering such a recent loss of his brother. He scoffs, sneaker kicking at the ground.]

...Still don't get how 'puberty' is a diagnosis of anything.
