hange would be very difficult to find if they're not in their laboratory, because there's the whole world outside their lab, and they're a free, wandering spirit. so whenever any of their friends try to find them, said friends look ridiculous, searching around in the shrubbery where hange may be collecting samples of who knows what, or walking blindly through the paths, eyes cast constantly upwards at thick tree branches where they know hange has climbed before to sit and to read.
and the 104th would learn this by watching their commanding officers look stupid staring at trees all the time, and they'd be confused: "captain levi...? what are you yelling up a tree for?"
and find out moments later when a rustling comes from above, and then hange drops down from the tree like the silly, curious hange they are. "sorry," levi says unapologetically. "i was trying to lure an idiot out of its nest. come on, shitty glasses."
and watch as the two of them saunter off, hange with a bounce in their step as they show off what they found, and wonder how this is the same officer who can switch so seamlessly to order and command on the field.
