I think that the blonde could possible be Ashley because if you've noticed, both people have a high pitched voice. It might not be the same voice actress but its a possiblilty.
This mysterious woman thats wiping out B.S.A.A agents, I believe, might be Ada. I don't have any evidence to prove it but it'd be cool to see her again.
Or what if its Sherry for either role? O.o
