I like Mugen, and I've had a lot of fun with the threads between him and Moiraine. You and I had talked briefly about the possibility of putting him and Jack Sparrow together and seeing what came of it, and that's something I still think could be a lot of fun.

If it were me, I'd say keep him. It's nice to have a character, every now and again, who you can just play without worrying about how he or she fits into things.

As for characters non-understood, well. I think there are varying degrees of understanding out there for some of mine, but it makes the facets of their interactions with others random and intriguing, for me at least. I remember going through a serious phase of "oh lord what have I done wrong with Moiraine," though, fearing that I'd made her untrue to her canon self due to how she was being perceived. The way for me to fix that situation was to show more in narration of her thoughts and motivations, at least a little, and I think it worked out nicely.
