I don't own a car and I'm an adult.
And there is a thing called home schooling. Though being a mutant flying squirrel doesn't affect his ability to learn stuff and sit in a chair and memorize answers.

Though there is the remaining question if Flint's transformation is addling his thinking. (Or if this new state of thinking in the part squirrel brain IS Flint's natural psyche now.)

I mean it can’t really work the same way for flint anyway. A goat is a pretty big creature so going “all the way” might work but even the largest squirrels are only a pound or two. Changing his dna to full squirrel would either mean he would have to Either shed at least 98% of his body mass or become a 100 pound squirrel which presents its own issues.( https://youtu.be/MUWUHf-rzks ) I understand she just wants to help him but even she must know this method would probably kill him.

Possibly, but if his regression to full squirrel were slow enough, maybe it would be okay, although... flying squirrels are much smaller than their non-gliding cousins. He would be losing a lot more body mass than, say, Jen... Given the level of intelligence the UTC squirrels display, I wouldn't worry as much about mental status changes, at least.

I can see where he's coming from. Kids adapt to new situations surprisingly quick. So if any Flynt's probably 100% on board with his new shape.
Though that last line. I know that fear. While change is inevitable, There's part of change that frightens people a lot. He's used to his body, and accepted it
He's okay with his sister being different to and he likes the person she is. The idea of her mind being wiped or him being stripped of everything he's used to?
I can't think of to many folks that'd be comfortable with that.

Wow.

"I lose me" is such a powerful statement. Bravo.

Really poignant final panel 😥
