Idk that is a really good question

Yup he is in Slytherin-

Ye ik but whyyy ;w;

He's a slytherin but he doesn't really act like one, wasn't albus a slytherin also?

I mean, there are different kinds of Slytherins. Not all have to be manipulative or evil-

And yup, albus potter is a slytherin as well

I feel like he would beg for Slytherin to not upset his father or family.

^that does seem possible. It could also be prejudice, I mean they are kinda associated with Slytherin now
