(Peter didn't betray them and Regulus went with Sirius AU)

Regulus was an antisocial person, that much was obvious, but he was trying desperately to rekindle his friendship with his brother. Well, was, because that was already fixed. Everything was forgiven, blah blah blah. Still made him slightly uncomfortable everytime he was invited to Christmas, but when he learnt that Sirius and his boyfriend, Remus, had acquired a kid, the discomfort doubled. Sure, he had his own little girl, Reinette, but she was mostly raised by Evan or Barty meaning she would be.. very excited at the fact she would get to meet her.. cousin. That would equal a lot of noise and.. Ugh, he didn't even want to think about it. Whatever, he should be able to handle it if he did get invited again, which he did.

As he arrived at Sirius's place, his little girl ran in front of him, pushing open the door and letting it close. Alright, he could already tell he was going to need a break. As he finally steps I to the house, he's met with obnoxious chatter and the faint sound of music. Ok, you can do this, Reg.

Kicking off his shoes and hanging up his jacket, he went around greeting people, and holy shit were there a lot of them.

About an hour and a half in, Regulus had already had enough, slipping on his boots and pulling on his jacket, he crept his way to the backyard, setting himself down on the back porch, the noise being muffled by the glass. Exhaling, he closed his eyes, taking a moment to appreciate the quiet before opening them again. Looking down at the snow, he grins to himself before taking a gloves hand out of his pocket and drawing a little heart on it. It was childish, but he couldn't give less of a damn right now. It was fun. After a couple minutes of drawing, he hears the patio door sliding open and closed before someone plops down beside him. Glancing up, he's met with a miffed looking kid. Tilting his head slightly, he gives you a nod

“Hey, kid.”

He motions towards his doodles in the snow

“Y'like my art? Handmade.”
