so like
when aaron was young and was with David, he thought it was normal and was glad he could have a friend he could trust (then he got shot lol). when he grew up, aaron was still very upset mentally, and never recovered from the event, nor what he realized he had done with him. aaron knew what David did was extremely wrong and perverted, so the subject is very traumatizing to him.
Brian, knowing that investigators were watching and that it was better to get answers than die with nothing, so he decided to ask a question
(before his kidnapping, the case had been reopened because someone came out as another victim. David also happened to be aarons childhood friend.
when the stream finished, brian asked simply who David was. aaron slammed the laptop closed, not facing brian. he talked threateningly for a moment before launching over and kneeing brian in the stomach.
aaron then shoved him up against the pole and started strangling him.
"where did you get that name?" aaron snapped, hatred lacing his words. Brian tried to croak out and answer, but aaron brought him forward by his electric collar and slammed his head back against the pole, nearly knocking him unconscious. He continued to wrap his hands around his neck, going to his ear.
"So i'll ask you again. Where did you pigs get that name?"
Brian mumbled something along the lines of "can't. .. breathe..", and aaron just slammed his head until he went unconscious.
aaron realized he was still live, so he huffed, getting up and turning the camera off.
