Yang and Sirius
Sirius continued eating his lunch, despite it's appearance and despite this conversation, and he considered Yang a moment before answering.
"I don't know. I'd honestly never really thought about it until I found out I end up there. Right now in my world there's someone who deserves it, but that's not how things will go."
This next part was tricky, with Peter and now Lily on board, but Sirius decided to answer honestly. Maybe it was because he didn't know how to react himself, talking to someone who knew nothing about any of them was a welcome change of pace.
"I don't do anything. See, I have this group of three friends, and we've always been close. There's a war going on, and one of those friends and his wife had to hide. They were going to use me to hide them, which is weird to explain but basically whoever they used would be the only person who could reveal their location."
He paused, trying to make sure she was following. "But I am the most obvious choice, so I guess I had them use my other friend, except he turned out to be a traitor and he gets them killed. And then because I'm the only person who knows it was him and not me, since the other two are dead, he frames me and fakes his own death? So I end up in prison..."
Sighing, he realized that Peter could be in the kitchen right then, cooking, unaware of the future that awaited him. Sirius may have kept calm so far, but since Lily's arrival he'd grown more angry at events that he'd yet to witness. That he may never witness.
"Anyway, I escaped years later, at least? But this place? Seems to be a better future for me, and I feel guilty for even considering that."
