Jack takes Paul into the Chapel to cool off.
Paul pleads with Jack to let him return to keep a vigil. Jack asks him if he poisoned Rose.

Jack says he was angry, and Paul says he felt the same way but not angry enough to poison Rose. Paul wants another chance to make things right with Rose before she dies, and Jack looks at the altar and snidely says, "You're in a chapel. Pray that doesn't happen."

Dusty asks Hal to check on Rose, but before he leaves, he tells him to pass along the message that he loves her, "She's gotta know that." After Hal walks away, Dusty turns around and spies Molly who heard every word. She lays into him hard, "You love Rose?!" Dusty yells back telling her she doesn't know what she's talking about and accuses her of being jealous. Molly knows her place and points out her role, "I'm just the woman you slept with while you couldn't have the woman you loved. You destroyed her! You were the one who brought poison into her life. So you get to live with that!" She's through with this joker, but before she leaves, she has one more zinger, "I guess I'm lucky I'm the one you didn't love."
Craig and Rosanna return home and find Lucy sitting on the sofa crying. The parents stand in the doorway and debate who should comfort her. Craig winces because he usually makes things worse when she is crying about Aaron. Rosanna leans in and whispers, "Well...don't do that." Rosanna walks off to check on Cabot. Craig gathers some fake compassion, then sits next to his daughter. Lucy embraces her father and cries on his shoulder, then she says, "Aaron and Alison...they got married. They got married! Not only is she having his baby. She's his wife!!" They hug, and as he whispers comforting sweet nothings in his daughter's ear, a grin surfaces on his face despite his urge to suppress it. Later, Rosanna returns and she tells Lucy about Rose's condition. Lucy wants to go to the hospital, but Craig reminds her Aaron might be there. Lucy hesitates.

Paul sits down next to Rose, and promises to make everything up to her as he strokes her hair. As the strength of life ebbs out of her body, Rose whispers with a serene smile, "Why did you do this to me?" As Paul tries to explain how he wasn't involved in poisoning her, Rose closes her eyes and then the heart monitor flatlines again. Lily is standing close by and screams at Paul to get away from her sister. John arrives, and everyone clears the room. Lily and Paul rejoin everyone waiting in the lobby. They all stand at attention and want to know what is going on. Dusty whispers, "Is she alive?" Before John returns, Lily zones out and says, "She's gone." Dr. Dixon joins the group a moment later with a defeated look on his face and only says, "I'm sorry."
Jack walks up to Hal and asks, "What do we do?" Hal says, "Now? We say good-bye to our friend...and then we find out who murdered her." The camera pans around first to Dusty, then to Barbara, and finally lands on Paul.
