Yes. I'm not sure who Riley really was, though. I don't know the details of their fight.
I know he does. He kept me safe, but I just didn't always appreciate his methods. Just before I came here, I was actually alone. I had distanced myself from both Derek and mom.
... So he's not just some random guy? I mean, I've seen him around. I just didn't think anything of it. We didn't grow up with our parents together, so I don't get like some kids do when mom starts dating someone.
