They stumble into Cassie's bedroom, still kissing, Cassie groping at Rob's clothes in the dark. She pushes his jacket off, draping it somewhere, then pulls at his tie to loosen it before lifting it over his head. He immediately resumes kissing her. Once she's kicked her shoes off, she has to stand on tiptoes to reach him. She can feel his smirk without seeing it and then he picks her up and carries her to the bed. She turns on the bedside lamp as he sits and begins the unsexy process of pulling his shoes and socks off. She giggles as she pulls her socks off too and stands up to undo her trousers, stepping out of them in an exaggerated striptease. He smiles and pulls her close to him. She starts to unbutton his shirt, feeling his taut shoulders.
They're interrupted by a knock on the front door. "Who is that?" Rob groans, his face against Cassie's neck.
"I'll get rid of them." Cassie pulls her clothes back on and leaves Rob sitting on her bed, putting a finger to her lips.
She opens the door to find Frank there. He raises his eyebrows at Cassie's disheveled appearance. "I was just getting ready for bed," she says. "And don't you usually break in?"
"I was just passing," he says cheerfully. "Thought I'd see if you'd changed your mind about being Lexie."
"I haven't." She folds her arms.
"Well, here's a copy of the file if you do." He hands her a small stack of papers, the close-up of Lexie's face arranged on top.
"I'd invite you in, but I'm busy."
"Give Sammy boy my best." He turns and walks away, leaving Cassie holding the file.
By the time she returns to her room, Rob has buttoned his shirt up and is putting his shoes back on. He looks at Cassie with an unreadable expression. "Saved by the bell."
"Yeah." She glances at the photo of her and Sam in the corner, suddenly feeling guilty.
"I should go." He stands.
"No, stay. Crash on the sofa..."
"OK." He nods, looking somewhat relieved that their friendship isn't ruined. He pecks her on the head as he passes. "Night, Cass."
"Night."
