Percy, being the faithful intern, follows. Looks like Chaos was right: You can never run from the past since it will always catch up to you; the best thing to do is to run towards it.

After being dumped by Annabeth Percy was just interested in having fun, making money, and testing his mortal limits through battle and the exploitation of his magic and growing knowledge... being an Avenger wasn't part of his plan. Oh well, at least none of them knew his real name and it was a great way to battle strong opponents.
