Bruin looked over from the path and saw Bellatrix messing with Kiera, one of the first year Gryffindors. He walked over and looked at Bellatrix, thinking back to their last, almost human conversation. "Now Bellatrix, you be nice to Kiera here or you'll have me to answer to...", he said with a grin. He knew that they weren't on joking terms, as no one probably was with Bellatrix, but he didn't care... "Don't think I won't come down here in throw you in the lake to cool you off if you get all fired up."
Bruin gave Kiera a little tentative smile, trying to warn her to tread lightly around Bellatrix and also let her know that he would be around if need be. "Have a nice day ladies.", he added as he headed off down the path, wondering who else he might bother today.
