Percy and Annabeth, along with most of Athena's cabin, where riding up the elevator in the Empire State Building to go the 600th floor. The floor where Mount Olympus is located. It was the Winter Solstice. So, most half-bloods where either already or going to Olympus to take part in the festivities. Then, they finally heard the 'ding' that meant they had made it to Olympus. When the door opened everyone gasped, no matter how many times you have seen Olympus it has thee same breath-taking effect.
By the time Percy had climbed the massive staircase circling the spine of the cloud on which Olympus was built, the meeting was over and the gods, goddesses, and half-bloods where now chatting, listening to music, and enjoying refreshments. "Percy," Poseidon cried, "long time, no see. Boy, have you grown. I see you are still flaunting around with Annabeth." "Yeah." Percy replied as he hugged his father. "Did you get her laid yet?" Poseidon asked with a grin. "No, why would you ask such a thing!" Percy blurted out without thinking.
Only four people knew that he was not the least bit interested in Annabeth. The four were Percy, Annabeth, Nico, and Dean. So, Percy made up a lie rather quickly to cover. "Annabeth wants to wait till she is married before she has sex." Percy lied. Annabeth lost her virginity to Dean Smyth, a handsome son of Zeus, the previous year. Annabeth was still having an affair with Dean and Percy didn't care. Annabeth's and Percy's relationship existed for this very reason, to cover for both of their secret affairs. Annabeth's and Dean's along with Percy's and Nico di Angelo's. Nico was about three inches than Percy with pitch black hair and eyes so dark they looked like charcoal.
