Pop quiz: Did you eat too many jelly slugs before bed and dream this up? No judgment. The theory mostly floats around because Snape is obsessed with Lily.
Some fans think “obsessed” might mean “secretly had a kid with her.” But here’s the thing: J.K. Rowling is brutally thorough. If Snape were the dad, she’d have made us cry about it in book seven.
Instead, she gave us the Prince’s Tale. That chapter is basically a highlight reel of Snape’s misery. No baby-making montages. Just a guy kicking himself for calling his best friend a Mudblood.
The Timeline: A Quick Reality Check
Let’s play detective. Harry was born in 1980. James and Lily were married in 1979. Snape was busy joining the Death Eaters and being Voldemort’s right-hand creep.

And let’s not forget the most glaring clue: the Patronus. Snape’s is a doe. Lily’s was a doe. James’s was a stag. Harry’s is a stag. That’s not genetics—that’s the universe screaming, “HE IS JAMES’S SON.”
