I'm alright with most of these things with both of my characters, but I need to request one thing regarding Barnaby here:

If it somehow comes up in context, please be careful with any mind reading, genjutsu, etc. Canonically, Barnaby has had some extreme problems regarding memories/thoughts/impulses/ his very mentality being altered. An IC problem is that it will most likely infuriate him, and an OOC problem is that we have no idea how far and deep this influences have extended.

tl;dr-- it's a huge problem for many reasons.
