Okay. So, besides leading the Hufflepuffs to the right Common Room (and really, he was making sure none wandered to the dungeons), then receiving Simon's owl...and heading straight to the Owlery to make a reply to it, Treyen finally made his way back to the Common Room.

FINALLY. Because he'll be free to rest now, will he?

Arya managed to leave him with very little appetite, which he regained on his way back and was now eating a muffin from the kitchens. Rather convenient, it was, that the kitchens were now open to students.

Either way, he moved the usual chair so it'll face the fireplace and took a seat. For the first time in quite some time he was tired.
