You know how Juno said that Percy would have to make a hard decision?

What if he has to leave Annabeth behind to lock the Doors of Death in Tartarus? That would be pretty much impossible for him to do, except she would probably be the only one smart enough to close it before a monster attacked her or something.

Except Rick pulls a plot twist out of his pocket and has her escape somehow afterwards so the Percabeth fans won't tar and feather him.
