KiShiDo beat you, Chopperman! :D
Halfmetal-lich, Hancock's chances are blurry at the moment imo. Either they're very high or they're very low. High if she just nurtures Luffy and finds a way to keep Amazon Lily safe when she's gone; low if she becomes his teacher somehow through-out the now probable timeskip. She could tell him what haki is and how it's used without it being a problem, but if she starts training him in the art of it, it will rather be a student-master situation and it would be awkward for the master to travel with the student, love or not. In my opinion. I'm not stating this as a fact, because I can still see Hancock joining.
Perona should be counted higher than .decimal if Moria dies. That would be quite a set-up from Oda's part, cutting her bonds and everything.
Wow I left it to AGOG to make the argument that Perona's chances increased because Moria might die smh.
Whether Moria dies don't means hit for Perona's chances of joining the SH crew.
Do elaborate. (I don't mean this in a "You're wrong" kind of way, I just want to hear your argument behind this statement)
