*no mention of such event*

Harry Potter and the Order of the Phoenix - BOOK

*Harry goes into Pensieve and sees James and Sirius picking on Snape very unfairly - Lily intervenes - Snape cuts James’s face open - James does a dick move - Lily gets pissed - Snape calls Lily a Mudblood for absolutely no reason whatsoever - Lily leaves them to it - James gears up for another dick move*

Snape: *interrupting* GTFO, BITCH!

Harry: HOLY SHIT MY FATHER WAS AN ASSHOLE! *warm and fuzzy illusions ruined*

Sirius and Remus: What up?

Harry: You guys. My Dad was an asshole.

Sirius and Remus: OMG NO! HARRY, SERIOUSLY! Look, James was an immature prat when he was a teenager and he did horrible things and WE’RE NOT DENYING IT and everyone regrets how they acted back then, but he grew up and became a better person and he was a great man, I swear. And it wasn’t like Snape was innocent because he was really mixed up in Dark Arts and James HATED Dark Arts so much.

Harry: But my Mum hated him omg.

Sirius and Remus: Dude don’t even worry about that it’s cool, she totally didn’t.

Harry: Okay.

Harry Potter and the Order of the Phoenix - MOVIE

*Harry breaks into Snape’s memory in a way that isn’t really possible for somebody who can’t do Legilimency and sees James bullying the shit out of Snape and being the biggest dick in the world*

Harry: ….. my father was an asshole.

*nobody contradicts him*

Harry Potter and the Deathly Hallows - BOOK

*Harry looks into the Pensieve and sees how Snape was in love with Lily but drove her to abandoning their friendship after becoming heavily invested in the Dark Arts and planning to become a Death Eater, and then finally calling her a Mudblood even though Lily was his only friend, and this is a totally rational reason for Lily to break ties with him and we already know that James Potter was essentially a good guy so it makes so much sense that Lily would fall in love with and marry him*

Harry Potter and the Deathly Hallows - MOVIE

*Harry looks into the Pensieve and sees that SNAPE AND LILY WERE SOULMATES OMG BUT THAT BASTARD JAMES POTTER TURNED UP OUT OF NOWHERE AND RIPPED THEM FROM ONE ANOTHER OMG IT’S SO SAD THEIR LOVE WAS TRUE AND NOW SNAPE’S HOLDING HER CORPSE LIKE A FUCKING CREEP BUT OMG SO SAD, GUYS*
