A/N: Based on an anecdote Rob narrates in the book "In the Woods".

...

One night, while lying in bed with Cassie, Rob decides to share his most embarrassing story.

"My first year at boarding school, I told everyone I had a twin brother called Peter, who went to a different school in Ireland. Non-identical, of course. I showed everyone a photo of the two of us. It's a good thing I didn't have a photo of Jamie, or I'd probably have made us triplets." Cassie smiles and snuggles closer to him.

"The next term I realised I couldn't keep up the pretence forever and stopped talking about him. When someone asked, I said he'd died in an accident during the school holidays. I'm sure it got back to the teachers, and my parents, but no one said anything to me." He's felt mortified about this for years, about the secret, concerned meetings that must have occurred behind his back, but saying it out loud to Cassie, it doesn't sound so bad. It's quite funny, really.

She's silent for a moment and then says, "Freak," with great affection.

"Your turn." He kisses her temple.

"My aunt got the priest in once, because I kept talking about Lexie. Think she thought I might be possessed." He laughs softly. "While they were downstairs I ripped all the wallpaper off in my room and said Lexie did it."

"Oh, come on. I killed my imaginary twin. You'll have to do better than that."
