Actually Doctor, I do have plans for that. I was going to wait until I closed submissions so future prospects wouldn't miss this post, but since you asked, I'll tell you now. 

Basically, while our characters may have been Erasure Agents for any given amount of time, they've never worked with one another. In effect, our characters will be meeting for the first time. I don't always do this, but I want chronicle character development from the first moment they meet and, that way, we don't have to make up background relationships and those said relationships can form naturally over the course of events. There will be plot reasons as to why they are brought together, but yes, they will not know each other starting off. 

Sorry for the late response too, I was at work until now.
