AU where Snape survives and names his son “Albus Harry Snape”

“Dad… what if… what if I’m a total dumbass?”

“Albus Harry Snape. You were named after two Gryffindors. Both of them were total dumbasses in their very own, unique way, and I am kinda responsible for the death of both of them. So… let that be a warning for you, son.”
