Also, about Gregory's aggression, I'm pretty sure it is 100% him being protective of Carmella. When they were bathing, Gregory tried to mount her and she didn't want it. So I separated them because I wanted to give Carmella a chance to take a proper bath. Once Gregory was away from Carmella, he went straight back to his snuggly loving self. Sat right on my feet and nuzzled me and didn't bite me at all.
