Annabeth had convinced Leo to go out into town with her earlier in the day. When they return home, it's no surprise that the house is dark inside. But what he wasn't expecting was an actual surprise in the form of a party.

He'd get back at his friends for throwing this after he told them not to make a big deal about it, but clearly he lost that right by pranking them all that morning.

Anyway, Leo will make his way around the party. Feel free to come greet the birthday boy, give him gifts or whatever.
