Black Brothers
"God, you're a dumbass."
Long used to insults to everything from his intelligence to his choice of shoes for the day, Regulus ignored his brother and continued packing his trunk. His attempt at an uneventful departure had been foiled by Sirius' presence, he wasn't going to add to the drama personally.
He found his resolve tested almost immediately as Sirius stomped over and slammed down the lid of the trunk, then sat firmly on top of it. "You're gonna die, Regulus. Don't you get that?"
"I'll die doing something worthwhile."
Sirius snorted, ignoring the jab. "You're still gonna fucking die."
