Sneed, seems to have this thing about she's aware she's ok looking, decent body but not hot. I'm sure little child Sneed felt left out being weird and kinda off putting but was not totally outcast. But she grew kinda jealous of the pretty girls who were popular. I wouldn't rule out wee Sneed the potato nigger probably really liked medicine, probably as a little girl liked the idea of helping and healing people. I don't doubt she's probably really into medicine.
But her crazy and ego hit in, she sees young girls who could/would grow up to be beautiful women. (she's got some fatties aside the point) so she takes the tranny angle and makes sure these girls don't get nice perky breasts and look like pretty young girls, girls so cute they could be insta thots, end up dating a rich good looking man something if Sneed didn't have money or career she'd be forgetable, what at best (ignoring her crazy) she's a 6.5?
She's single, makes bank multiating kids, if it wasn't for tranny timeline she'd probaby be a real bitter no one hating young girls on some weird reddit.
