[People messed up. Tadashi understood that. It had taken him eighty four tries to get Baymax to function properly. He'd watched so many of his classmates screw things up before he told them that they could try again. Hell, he'd been thinking since waking up in Caer Glaem that he'd messed up pretty badly himself, running into the building while it was on fire. As long as people learned from their mistakes, he'd always said.

His eyes widen a bit when Hiro says 'your lab'. Of course that'd be how Hiro got settled into one so quickly. Tadashi gapes for a moment before he smiles a bit in relief, reaching to rub the back of his neck.]

That's...that's great! Man, just think. A few weeks ago I was rescuing you from bot fights gone wrong and now you're a proper nerd.

[His voice is teasing, though there's still underlying worries. Something really big?]

So you're working on a project together, huh? I bet whatever it is, it's going to be great.
