She is taken to dinner by her boyfriend Orlando, an older man whom she has recently moved in with. That night, Orlando wakes up in a daze and complains he does not feel right. Marina prepares to take him to the hospital, but he stumbles down a flight of stairs. After driving Orlando to the hospital and checking him in, she is told by a doctor that Orlando has died of a brain aneurysm. She runs from the hospital and is then picked up by police, who drive her back and demand an explanation for why she left so suddenly.
