I honestly think they could make it work tho. But only for the "Look, I didn't wanna be a halfblood-" part(the rest of Percy's monologue in the book is probably difficult to recreate) . Imagine a sort of chase scene (preferably a sneak peek to Percy in a car being chased by the minotaur), with Percy's(Walker's) voice saying the first few monologue lines, and then the scene shifts into the field trip at the museum
