Dooku decides it would be a very good idea to seduce Obi-Wan (maybe for a Separatist cause, maybe because Obi-Wan is fine as hell. Maybe both) The thing that surprises people the most is that it might actually be working.

Dooku is a charming, suave and handsome guy and I feel like his and Obi's interests would be rather compatible. If only it wasn't for that pesky Dark Lord of The Sith thing, but then again, people can be ... swayed back to the light ;)
