Hehehe, I am liking the 'Wild Card Mystery' that Karin seems to be.  I think I'll have her vaguely describe her primary jutsu and mainly have her explain her Tai/Genjutsu skills, keep them all on the edge for a little while longer   ::)  When the ambush happens, they'll see what she can do soon enough.  Can't wait to see how they react to puppets   >:)
