God why would you ask me this...MAN OKAY obviously the Diary of Luke Castellan (because soda-dispensing goats and exploding buildings and Everything), his last conversation with Percy in the woods at the end of TLT where he has the pit scorpion and Percy tells him he's brainwashed and he denies it, the fight on Mount Tam with Thalia, the conversation on Princess Andromeda with Percy and Annabeth, being hit in the eye with Rachel's hairbrush and when he breaks his possession, and literally the entirety of the time in the throne room in the last book.

I want to regain all of these honestly. I've regained some things (how he met Thalia, the tigers growing out of teeth, the promise to Annabeth) but some of his more intense canon points I'll probably prolong them a bit and then brutally destroy him and see how that goes. It'll be fun, he's already questioning if he's actually related to Annabeth

It's fine this is fine
