So Haggis and I got to chat and clear up the confusion. Mithias has yet to be accepted as a Blackmoore. We will have to see what happens IC. 

This is my proposed edit to my previous post. It's only fair that it should be modified since I was under a false assumption at the time I posted it. This is almost exactly the same and may make the future of this thread smoother for us all. Alistair can still take offense if that is IC for him, since it is basically the same thing anyway:

"You are. This is the family I choose." Clearly Mithias meant business. He had claimed his brothers descendents and wasn't going to back down.
