I'm sorry to get you to explain this again, but I just want to be perfectly clear on this point before I start writing.

I can only have Jaken interact with a particular character once, right? For example, only one fic where Jaken and Sesshomaru are the focus. But can other characters make appearances (but not be the focus) in more than one fic? What I mean is, can I make a small mention of Sesshomaru in other fics?

Thanks.
