Vickers descended from the dorms and was on his way to the Owlery when he heard some... commotion?... as he passed through the common room. First there were those arguing over a chair, which he vaguely recognized to be the one used most often by Ellie Stone during her stay there-- and then there were those who were set to build something.

Build something. That was like a key word with him. Comfy couch? Not quite the same pull as BUILD. So he makes a detour away from the door and headed towards where Head Girl was giving instructions. He gazes at the enlarged image "A cat condo? Nice." He can help build that. If he managed a swing trellis this is noooo problem.
