Remus permitted
Every time the chance came up, Remus had to allow himself to smile. Because, after all, when had been the last time he was truly happy-when had he had a reason to smile?
When he was with James, and Sirius, and… Peter.
But they were gone, and weren't coming back. He was alone, now.
And every smile- every laugh was a betrayal to them, a memory he was losing. Every smile- he felt guilty, and he hated it. They were gone, and he was alone. (After all, he was the one who was still alive- the only one who had even a tiny reason to smile.)
