So I am doing this meme with everyone else: Give me one character or pairing in a fandom I'm familiar with, and I will give you a sentence or two of fic.

( And the resulting fic... )

Title: Corresponding Shapes
Fandoms: The Royal Tenenbaums/Lotrips
Pairing: Margot Tenenbaum/Billy Boyd
Rating: PG-13

( So, you're cheating on me, then? Billy Boyd asked conversationally. )
