[@Akayaofthemoon] Oh man.  I'm half tempted to give out some character spoilers for Spinel right now.  I won't, but suffice to say whether or not she ends up joining Bloodstone is going to be completely up to the GMs at this point.  If I'm even allowed to have her join Bloodstone, the one thing I'll say is that she wouldn't betray Aquamarine to her face, but otherwise it's a toss-up.
