//I've yet to decide Rune's official fate (probably won't be this but it is tempting) but I do wanna share this angsty idea I had.
TW: Death
The second Wizarding War is over. Everyone's mourning the lost, helping those injuried, in the chaos, Rune's siblings run over to him. He's bleeding heavily. One of them tries to help him sit up or get to his feet but it's obvious by the dulling in his eyes he's very unlikely to make it. Despite this, the pain he's in, and the fear and sadness his siblings show, he can't help but let out a choked laugh. He, once Salazar Slytherin, changed his ways. He died on the right side of the war this time. He could no longer be a traitor. He'd fixed things. He cups the cheek of the sibling holding him with a shaky hand.
"I-Its OK. I'll be f-fine. We did it. We're all on the same side again. I-I couldn't be happier!"
