Peter slipped out after putting his shoes on, however he went a different direction then the other two. He headed to where he kept his pet eagle owl. This whole matter left a worrying not in the pit of Peter's stomach, something that caused his brows to draw down in a furrow, teeth digging into his lower lip.
James had seemed almost exited about this, Remus grim. No doubt Lily would be quite cautious; after all, none of them had any idea how Sirius might react if he caught them following him. He had been acting too strangely as of late for them to predict his mood.
Once in the Owlery, Peter waved his owl down and quickly attached the small note to his leg, watching as he took off through the large opening in the wall and swooped around the castle.
Glancing briefly down at the grounds and the few lights that that were still on, Peter gave a low sigh. Turning away, he left the room and began to head down, just as he told Lily he would.
It was never too difficult to locate James, and since Remus was with him, Peter could only expect to reunite soon enough.
