Remus/Anyone in the Great Hall/Main Hall area
This was the part Remus hated about the war. The waiting. Knowing something was coming but unsure of what and unable to stop it ahead of time. It was like before. Everything rushing by in a whirlwind: people living like life was too short, getting married, having kids too young because there might not be another chance, trying to pack a lifetime of living in a few months. It was just like last time, and that's what worried him. He was terrified he and Tonks would end up like Lily and James, and that was not what he wanted.
Remus had half considered patrolling the areas of the castle he knew he could pass through with ease due to the Marauder's Map, but the large Great Hall seemed to be a more vulnerable area to him, and thus where he stationed himself upon his arrival to the school. Already he seemed to be a bit on edge. He was anticipating the attacks in his mind as he walked around, wand in hand with the handle tapping against his chin, his senses alert as he casually sniffed the air for anyone unfamiliar.
