...so there are some considerations here.
First of all, there's his gang, obviously. One fewer person means one fewer pair of eyes, one fewer pair of hands, one fewer brain. But he's tiny and far from their strongest member and honestly there's not much he can do that Nat and Nico can't, so it's not like he's leaving all that much slack to pick up.
Second of all: Auradonian families aren't likely to treat a villain kid well, even if the king did hand-pick them. Oh, it'll help that nobody knows who the hell his parents are and wouldn't recognize the names if he did tell them, but it probably won't help that much.
Third of all: homeschooling is what your parents do to you if they're the sort of people who lock you in a tower.
But. There's going to be food, and light, and Auradon is clean, and probably people try to hurt you less there, although he's careful not to put too much weight on that.
"So you're going to talk to Mother Gothel and Claude Frollo and expect them to do what's right for their kids instead of keeping them in towers forever? That'll go awesome," he says instead of any of that.
