His eyes narrowed on Bob as he waited for the man to exit already, once he did he took a step back in to grab the door handle and close the door behind him. He didn't even bother with the key. "Can you take the stairs?" then he broke in laughter with a wince. That hurt. "There isn't any other option" he shook his head and walked down the hall completely forgetting their deal to walk side by side. And when he realized that he halted a few steps down the hall, Bob wasn't himself and he still had his wand out, for all he knew he could hex the Hufflepuff and all the students along the way.
