chunk: During her stay, Sara overhears a conversation between Rebecca and her father (Tomas Arana), hinting Rebecca has had trouble making friends in the past. Rebecca's mother (Frances Fisher) mentions that Rebecca is supposed to be taking medication. She and Stephen later find a bottle of Zyprexa pills, used to treat schizophrenia and bipolar disorder. But the bottle is full, implying that Rebecca hasn't been taking the pills. Sara, worried about what would happen, decides to move in with Irene. Irene goes to a club where she sees Rebecca. They make out in the club's bathroom and Irene, not knowing that Rebecca is Sara's roommate, takes Rebecca back to her place. The following morning, Sara goes to Irene's apartment but she's not there.
