(this is a modern AU where he also had a kid named Atlas. Cool? Cool.)
Mundungus never thought he could be this shitty of a human being. Who kills their own kid? Terrible people, that who. He didn't deserve to mourn this loss, it was his fault, yet he did. It's not like he was working, anyway, he could take all the time he needed. Funerals or whatever could wait.
Weeks had passed since his “mistake” and all he had been doing was drowning himself in alcohol and sleeping. Not much has changed, really. He had terrible nightmares, sure, and he was constantly worried the police would come knocking.
Speaking of knocking, Mundungus is suddenly pulled out of a nap by some knocking at the door, a wave of panic immediately washing over him. Why hadn't he heard sirens? Were they trying to be discreet about it? What the hell? After a moment of waiting to hear the signature “this is the police”, which never comes, he slowly pushes himself off the couch, steadies himself and makes his way to the door, peering out of the small window to see who was out there.
Once he suddenly registers that it's a child outside, seemingly about how old Atlas was, the door is open in a flash, nearly making you jump.
“Who the fuck are you, kid?”
He snaps, his eyes going to the series of containers you were holding. Food? Why did you have food?
“The fuck you want? How'd you even find this damned place?”
