Do we really have time for more upgrades?

[Hiro isn't sure how time might be weird here. And he definitely doesn't want to spend too long and have Aunt Cass freaking out about him being gone. But there is a sigh of relief that she seems familiar with the port Baymax uses. Or close enough to it, apparently.]

Yeah? That's good, shouldn't take too long then! Uh, I'm not sure if I should offer to help here or just.....stay out of the way...
