That's gonna be the big thing. The BFC isn't an actual group and one group member is half dead xD So... yeah. This will go lovely.
Edit:
Like Asterion hasn't physically met Matthias (and their friendship/alliship/whatever the fuck you wanna call it) isn't strong. Bella and Asterion has never met. I don't think Matthias and Bella have ever met either? Asterion is not really about Emily and once he realizes Bella and Emily are in ties together (I don't know if Asterion will be willing to work with a cop even if she's a dirty one). He might get suspicious. Emily and Matthias haven't met yet either. Etc... Etc...
Funny thing is that Emily and Matthias have, in fact, met face to face and everything. Gurl just rolled up to church n everything.
