As much as I think Ceria would hit it off with Harb's group 1 charrie, I actually don't think the two groups should run INTO each other.  Perhaps they can pass through the same area at different times and be like, "Huh, another group passed by this way. Wonder who they could be?"  but both groups are already so large that I'm afraid any resulting mish-mash meetup would just result in chaos and confusion.  However, I'll go with the flow since what thou sayeth is law.  #YouTheBoss
