Baymax is pretty amazing. [There's no doubt there.] Tadashi put a lot of work into making sure he'd be able to help a lot of people, but he never considered him to be something more than a robotic nurse. [He can probably hear the grin in Hiro's tone.] I only had a couple of days to really perfect it and maybe I'll make some upgrades some day, but it did what we needed it to do. Baymax's exterior's made of vinyl so protecting him at all costs was important.

...and flying just seemed really cool. [It's true. Sometimes he has childish desires.]

So you're probably from even further in the future than I am. [He might just be impressed about that.] What're the space colonies really like? Why did you come down to earth?
