The Social Worker in charge of Willow’s kids’ cases regularly reminds herself what foster parents who take in unusual children and keep them happy, healthy and well fed are worth. Even if said foster parent creeps her out and is the sister of a Mob Bosses. Also that angering a Mob Bosses sister is a bad idea and she should probably just accept whatever explanation she’s given for the random kids she didn’t place there but has paperwork for anyway.

All this except for the Hank connection: Hank is four hours away in Portland, and he’s not that notorious outside of Portland.

A big, happy family

Willow(to her children): If you’re happy and you know it, clap your hands!

*A thunderstorm of applause raises from outside*

Willow and the Plieds look out the window to see Henry in the garden. There is a thunking noise as he slams his head against the cherry tree. There is a second round of applause.

The Magic School Shack

So lots of kids live in the Wandering Shack, and are presumably educated there too since ze’s always moving around, and so the kids can’t go to a regular school because those are stationary. Thus, I headcanon that some children brought in by the Shack might stay and teach when they grow up. And everyone knows the best part of going to school are the field trips, and the teachers and the Shack doesn’t want the kids to miss out on such a fun thing because they don’t go to “normal” school, so where might they take them?

The science teacher, a redheaded curly-haired r!Mabel, usually has the zaniest ideas. Their suggestion to visit the inside of an active volcano wasn’t even the most memorable, and it erupted glitter that day. Not even Alcor knows how they got THAT to happen, and he was THERE. The class agreed that it was all very educational, however.

Gliese foster branch

I have this headcannon that Willow’s child collecting tendencies end up getting passed on to (some of) her children, and (some of) theirs, and so on and so on for generations until it ends up becoming an official branch of foster care, geared specifically towards orphaned (or otherwise in need of care) children due to cults and/or demons. These kids would most likely need some special therapy, may never fully recover, and it would probably be wonderful for them to live in an environment where their little quirks that are just a tad bit stranger than most aren’t looked down upon or mocked. Kids who absolutely cannot stand fire, or must avoid forks at all costs, or will have a full blown panic attack at the smell of bubblegum fit in just fine here.

What was originally one house in Gravity falls spreads to hundreds of houses all over the world. Councillors and foster parents who wish to work in the Gliese branch must undergo much more special training than normal, and be prepared to do their own research if a child comes in suffering from a demon or cult they’ve never heard of. Only the best wards are placed on these homes, and an extra security detail is always on call in case of vengeful cults or parents. 

And of course, throughout the years, the “Gliese” name always stuck around for some reason, and by the time they became official the name was stuck. And if the occasional omniscient dream (dork) demon comes by to drop off a child, they’ve learned not to question it. 

Because of Willow’s issues with foster care, children welfare groups lobby for magical contracts to be included. Can include legal parameters, conditions and requirements to be a foster parent, and immediate penalties should any of the conditions are broken/the children are in direct/indirect harm, outside of legal/criminal penalties. I’d also like to see someone sneak in a clause Alcor (one of his cultists?) will visit them, since he also starts developing a reputation of protecting children

HC: One of the niblets, probably one of Willow’s many foster kids, grows up to make a magical girl type cartoon about Mabel and her adventures, with the basic premise that Alcor chose her as his champion to help fight the forces of darkness. Cartoon Mabel has to deal with both school and the forces of Darkness as Mizar, Twin Star. (Later seasons include: a trio of fighters that turn out to be Mabel’s kids from the future, a cartoon Henry who turns into The Woodsman and ends up with Mabel, etc.
