Do you mind if Mokuren tags your character? If not, would you rather I not mention the rape at all?

Feel free to tag! :D Mentioning is fine, but beware Faith will respond vehemently - she's got a little bit of a history...

Do you mind if Mokuren sings around your character?

Nope. Though expect Faith to complain. ;)

Can Mokuren sense when your character is speaking telepathically to someone else?

Sure!

Can she show you visions or speak with you telepathically herself?

Faith might object - but sure. :)

Is there anything your character can do that might interfere with her powers, or anything else you think I should know about them?

Probably not? She has a sort-of-psychic link to all other slayers via the shared powers; but that's very rarely active at all.
