Who guessed it was Annabeth????
He said he just wanted to jump out and yell ta da!

I was like do it its Annabeth!!!!!!!

And at the end when he was just like I lose a bet.
He tells Annabeth his life has been more messed up than hers and she's like
" let's bet, lunch?" And he's like "I know a great falaful place"

Hmmmmmmm, seems to be missing some pages.(Totally like that too in The son of Neptune when Percy was like "guys get ready to meet my other family ")
