/nodsnods. While it may not drive out the Mara (the mirror thing does that, it can't stand it's own reflection) but yeah, I'd say it would hurt him, without a doubt. With what's happening in the thread so far, I hope I'm writing his reactions OK to what Will can do! (Tell me if I'm not! That's an order. :P )

Is that a way you'd like to take it? I have an idea for a next tag but wanted to check with you first. Trapping him in a dream (or nightmare) could be a possibility (as a point to work towards)?
