Ok I might be crazy for this but-
I genuinely do not remember/know if this has a canon explanation, but why did Snape NEVER see Peter at ANY death eater meeting? LIKE ANY AT ALL. Or like idk smn MENTIONING PETER?? It just makes 0 sense to me
It's impossible Snake didn't go to tell Dumbledore to keep an eye out for Peter bc he might be a spy for the dark lord! And yk Snape didn't know Peter was gonna be the secret keeper or wtv, but Dumbledore did
AND notice how Neville's parents are the ONLY ones who got tortured/badly hurt? Like they didn't receive ANY help from Dumbledore like the Potters, or at least it's not mentioned (?), again, this is just from the top of my head (also not to mention they were as much in danger as the potters were)
DO YOU SEE WHERE I'M GOING W THIS???
Dumbledore could have literally planned to leave both Neville and Harry without families so he could later manipulate them both as they grew to kill Voldemort
Bc when no one cares for u and then suddenly u find out this old man cares sooo much about u and he'll keep u safe, wouldn't u trust him?
Not saying this is canon, but yeah
