"I haven't suffered from memory loss, no," Remus replied, grasping to his patience by the skin of his teeth. Everything, it seemed, was going to be either painful or insulting with Sirius. He'd forgotten how it was, towards the end of... it. He wasn't even sure what to call it now. Had it been a relationship? Could Sirius have loved him if he hadn't trusted him enough to tell him that they switched to Pettigrew? Or had it simply been a fling prompted by fear and sustained by desperation?
Remus had always possessed these doubts. Even before, when Sirius wasn't so difficult, they had lingered in the back of his mind.

Curling into a ball and disappearing may not have been an option, but getting part way there helped him keep some semblance of calm.
