What does Alaska tell Miles when she awakens him in the night in "fifty-eight days before"? How does Miles respond?

Miles is awakened by Alaska, who confesses that Takumi was right about her ratting out Marya, and then asks him to stay with her at the school over Thanksgiving. Miles, eager for time alone with her, agrees, later explaining that she doesn't go home because she's "scared of ghosts ... and home is full of them."
