Mundungus knew he could stoop low to get out of things, yet this was wrong even in his books. He could have chosen any Death Eater off the top of his head. Any. Yet the fucking name he had decided to blurt out was yours. Of course it was bloody yours, why would he do that? He knew why, and he also knew that he is a selfish, horrible, pathetic excuse as a human now. That it will quite literally be set in stone, along with you. Of course, since he was the one who admitted it, he was the main part of the plan. What was the main part of the plan? Oh, to kill you, of course. He had built the best relationship with you out of all the Order members, so he would be the one you trusted the most, right? Yeah... Probably not.
After a brief meeting with the rest of the Order members about the plan, he slowly made he way upstairs and to the room in which you were staying in, as if subconsciously buying himself more time before he killed someone he could call his friend.. Jesus, why was this so hard? You had definitely killed more than one person, so why was it so hard to kill you? There was even the added bonus of when he killed you, he would have less dept to pay off to people. It was a good situation for him, so why didn't he feel like it?
As he arrived at your room, he took out his wand, undid all the protective enchantments surrounding it and unlocked the door, stepping in and taking a breathe
“'Ey, kiddo. Wassu-”
He cuts himself short when he finally turns around, your dorm that's usually splayed out on the floor or bed now upright, pointing a wand with clear aggression at him, a look of betrayal already on your face
“Woah, woah, 'old on 'ere, kid. Why so aggressive? 'M 'nly 'ere for a chit chat. Put it 'own, will ya?”
