Rob clutches Cassie's phone to his chest as he sits alone on her bed. He tries to hold on to the memory of the last time he was here, in this room, when everything was peaceful and perfect for once. It keeps slipping away from him, though, and all he can see is Cassie's face calling him a coward. He deletes the message he left on Cassie's voicemail and calls her number from his own phone again.
"Cassie, it's me," he begins, the tears still evident in his voice. "Cass, I'm sorry. I love you. Please, come back to me. I need you."
He listens to this new message on Cassie's phone. It sounds just as pathetic as he expected. Deleted.
He calls her a third time and this time he takes a deep breath before speaking. "Cassie, it's Rob. Come back, Cass. I want to tell you something."
That doesn't sound too bad. He puts Cassie's phone back where he found it before he can change his mind again and pockets his own mobile, taking one last look around the bedroom. He remembers Cassie's request just before he leaves the apartment and places his spare keys on the coffee table.
