I am a fan ov both A' and X', to get the point through.

We have seen on three ocassions of X' into A', bc A' doesn't have a set standard for who joins based on how you got your abilities. X' does, but that's self-explanitory. Although, very few A' could go into X', four come to mind.

I think, on some level, we all know that anyone can be given the call to be an A' or there is a event that show's that someone can be a A'. Does it matter that they are or were ever a X' before?
