Betrayal

Sirius returns from a mission with the Order, believing Remus is the spy who wants to betray the Potters to Voldemort. I've just written the scene in my fic "We Can Be Heroes" where Sirius begs Remus for forgiveness for betraying his secret to Snape, and it got me thinking about this part of the story. I hate how awful things get for Sirius and Remus, I love them.
