on a solo quest, Nico got trapped in a gigantic jar and the others found out because Percy dreamed about it. In Percy's dream the jar had three scraches on the side, when he asked Hazel, she told him that pomegranet seeds put Hades kids in a coma-like state that lasts up to a day, and that Nico has eaten three. Percy: So what do we do? The seven made a plan to find Nico and free him as soon as possible. The seven made their way to the spot described by Percy's dream and were surprised to find a gigantic jar in the middle of an open field. Frank: That's a huge jar. Leo: Do you think Nico is in there?
