'I'm going to kill Bellatrix LeStrange.'
It had been a couple of weeks since the battle of the department of mysteries. Remus felt he was alone once again. He had the New Order, but it wasn't the same. The marauders were gone. James and Sirius were dead, and Pettigrew betrayed them. Remus was the last marauder standing.
Remus sighed, opening the door to the shrieking shack. For once in his life, he was looking forward to transforming. Remus just wanted to feel like himself again. When Sirius started living at 12 Grimmauld Place when the Order took over, he accompanied Remus every month. The men felt James's absence, but Sirius managed to keep Remus from attacking anyone.
Remus sat on the floor. He knew he couldn't go after Bellatrix, no matter how much he wanted to. If something happened to him, Harry would be alone. He had to stay strong for Harry. Once they discover how to defeat he-who-most-not-be-named, karma would come to Bellatrix and the other death eaters.
The full moon peered through the nearest window. Remus was helpless as the transformation happened.
