chunk: Rebecca gets Sara's sister's name tattooed in the same place on her breast as Sara, saying that Sara can now think of Rebecca as her sister. A shocked Sara realizes that Rebecca is obsessed with her and packs all her things, except her sister's necklace, which she can't find (being later revealed that the necklace had been stolen from her by Rebecca). Jason arrives at Sara's dorm and slips a note under her door, saying that he wants to see her. Rebecca reads the note, impersonates Sara with her sister's necklace and tattoo, and dyes her hair to look like Sara. She then goes to Jason's hotel room and stabs him to death.
