Happy New (belated) Year, everyone!
EDIT: spoiler for shippuden 29-30 (to soothe the uproar)
I was having a discussion with a friend and the subject was Kakashi's sharingan.
Besides the old mysteries (aka origin, design, abilities etc) he pointed out something really interesting.
I think I've never seen this little tidbit anywhere, but the discovery reveals a major plot-hole.
Kakashi can't turn off his sharingan-eye. So how on earth is he able to turn in and off mangekyõ sharingan?
All credits to dear Pärtel :)
