I'm challenging someone to write a short fic about a case where Reid becomes the subject of interest for a cougar (older woman who likes younger guys). The cougar is part of the investigation, and it's necessary for Reid to at least tolerate her advances for a short while. How does he take the attention? How do the others react?
Really, you can take it in any direction you like. As long as Reid and a cougar are involved, I'll consider the challenge met. Happy writing!
