Dean smirked before falling into listening mode, the topic of beating Harry up a bit unimportant; he would not be distracted from the topic of conversation. So sitting there, listening, he watched. Using what he knew of the younger man he attempted to piece together all the things he was not saying; those missing bits of information.
"So, the day the storm cloud rose up, you got into a fist fight with Draco Malfoy; ex-Death Eater and school rival. Gotta admit, the fact you were in his life enough for that to affect you is interesting." He rose up a brow. "Especially if it was enough to put you in this funk."
He then leaned back a bit, pursing his lips and tapping at the table top. "I take it to mean the other part is when the rumored injuring of Oliver Wood happened? You know, where the rumors say there was blood, but word at the office is that it was a minor hex needing only a warning?" Fingers kept on tapping as he considered Harry passively.
"Fucking hell, Harry. What are you thinking? Is there anything else you're not telling me here, kid? I can't even see you doing something like this for one of your school or war time friends, let alone him. So yeah, not comprehending this."
