Ahsoka is on a mission to Tatooine, and there she finds out Obi-Wan is her contact. They end up back at his hermitage, and they find out just how starved for contact and affection they both are, and fall into bed together.

Bonus points for Ahsoka asking Obi-Wan to come back and join the rebellion with her (pretty sure the Rebels might devolve into fanboys and fangirls if they had the famed Negotiator among them), but he refuses, saying his place is here, even if he cannot divulge exactly why.
