MIT is always full of tourists, and sometimes they ask for directions. Bruce is pretty used to this; he gives off enough Aura Of Student that he's asked pretty frequently for restaurant recommendations, T stop locations, and what have you. So when one guy with a long white beard asks for nice places for sightseeing, it isn't particularly memorable. He suggests the Harvard Bridge and the observatory on top of the Prudential Center and makes some crack about how if you can fly the view from the top of the Green Building is pretty awesome too. Then he wishes the guy the best and goes about the rest of his day.
"The previous Santa. Managed to turn giving children presents into a supervillain plot."
"...don't supervillains mostly plot to, like, pollute the earth for unclear reasons or something?"
"Mind-controlling the populace for unclear reasons is also a popular one! --Also to be clear if supervillains actually exist I don't know about it."
"It was for a very clear reason. The reason is that he thought that the Christmas spirit was best served by children having blind faith in spite of all the evidence."
"Okay, fair, that's less 'supervillain plot' and more 'terrible internet fiction circa 2010 villain plot' but still."
"There's stories about how wanting people to have blind faith in things sucks. I don't know of any featuring Santa in particular but it wouldn't surprise me, the internet is vast and strange. Does the North Pole have internet?"
"We haven't bothered to get it yet, we didn't know if the humans would get bored of it."
"I'm pretty sure it's sticking around. Maybe not on the time scale you care about, I guess. . . . I should probably figure out if I should move to the North Pole or not, if I can be more useful there then I should but if I'm only useful on actual Christmas I should stay in school."
"I probably do, yeah, if there's more stuff like the mind control. Sorry." Philosophical conundrums about the ethics of interfering in alien cultures: also very Star Trek.
"I don't know anything about what humans learn in school, it might be important. But I think your best chance of changing things and having them stay changed is by coming to the North Pole and dealing with it."
"Then I should go. Also I really want to see the North Pole. Also, if any of the changes I've suggested sound like bad changes, please tell me? You know more than I do about this, I am super not qualified."
"I think you want to spread joy to all the children of the world and I will definitely tell you if it looks like you're not doing that."
"Thank you." He kind of wants to go to the North Pole and see the secret magical city and find out what his brain has been doing to the abstract concept of Christmas but it turns out he can't actually suggest leaving the Moon.
Oooh, excellent idea! Moon bouncing! Bruce is going to find out how high he can jump.
He can jump very high, because the moon doesn't have very much gravity.
"...I really like being on the moon."
"It's really great. You picked the best possible way to show me magic exists."
"...I think you just have good taste in magic! Some people would rather, I don't know, be transformed into a taller man with giant muscles."
"I can understand how some people would find that convenient but having my body modified on me would been quite the shock." He looks down at himself, notices his footprints in the regolith and smiles.
"At the North Pole? Yeah." He really wants to come back here sometime, but he's asked for enough things from someone who might not feel free to refuse already today.
Teleportation: not much less disorienting the second time! Also still extremely cool.
