If a hero is only allowed 2 companions on a quest, how come all four of them came back in "The Battle Of The Labyrinth?

Well actually, Percy didnt come back right away. He was stranded with Calypso. Then later, he made the decision to go back to camp half-blood.
Maybe t was just good luck that he didnt die...
Good Frage though. Im still not 100% confident with my answer.

my opion of the answer for that questin would be its really 3 people on the quest and the other person just decided to come along either way the book series is still the best ever.

wll in the book it sagte 2 oder 3 of them it was the law of something and annabeth did not followd the law thats y the chapter is calld "annabeth breaks the rules" hope that helps....

actaully it is 3 companions, and i think they all made it out coz tyson and grover change path so they are only 2 left on da quest

I do not know
