Regulus
Regulus was stressed.
Sirius had run away last week and he knew he wasn't fit to be heir in his stead. Hadn’t been raised for it like his brother had been.
Why couldn't they just go back in time, find a time turner somewhere in the horror that was their dark house, and just go back to when they were all happy - or at least happier than they were now.
Regulus supposes that Sirius is probably happier now that he's gone. He’d always preferred Potter over him anyways.
And yet, still, Regulus missed his brother more than anything. Missed when they were young and Sirius would tell him stories. When they would play hide and seek, or quidditch. When his brother loved him.
But now all that’s left is stress and the impending doom of a dark mark being forced onto his arm.
