You, Grover, Percy, and Annabeth are on a train ride to Los Angeles because you guys are going to the Underworld. It'll take a while to get there. You guys rented cabin 17. The beds were arranged weirdly. You and Percy's beds were on the floor, Annabeth's bed was above Percy's feet, and Grover's bed was above Annabeth.

Annabeth and Percy were having a bit loud conversation, and woke up Grover.

Percy: "Ya awake now?" He smirks.

Grover: "Yeah, now I am..." He said, annoyed.

Percy: He's not used to Grover speaking like that. "You alright-?"

Annabeth: "He's fine, it's just that he's super grouchy when he doesn't get enough sleep."

Grover: "He's super grouchy when he doesn't get enough- nyeh." He mocked Annabeth, still a bit annoyed.
