Too many questions

Now that Mako has been informed on what happened to her family and Satsuki revealing her (evil) intentions, what's left now is how will Mako react to this? Will she keep her twin's identity or take back what's originally hers?

And most importantly, who is the traitor among the Watsuji's? I had my suspects but his motives are unknown to me.

So far, the story is still engaging.
