Re: James & Remus
Remus was focused on making sure Peter and Fenrir felt comfortable, not as though they were intruding on the evening. He was focused on staying close to Sirius and making sure he knew Remus was still there, that he wasn't going anywhere. Honestly, it was probably a good thing, in a way, because it meant he wasn't focusing on what was coming, the pain of the transformation.
But, he wasn't so focused on the three of them that he missed James separating himself from the group.
After watching his friend move around the pitch for a bit, Remus left the others with a quiet word and went to talk to James. He made an effort to not walk as silently as he could, seeing the tension in James' posture. It wouldn't do to startle him and get someone hexed on accident. Coming up beside him, he stayed standing, rather than squat down as well, not wanting to be seen as invading the moment if James really just wanted to be alone. He didn't ask if James was all right because he assumed he already knew the answer. So, instead, his question was "You going to be okay tonight?"
