Lee got sober a bit too soon.

Kimi's technique is a little flawed on the science half of it. If he's transfering all the calcium from his body to make spikes outside, then there mustn't be much calcium inside his body. Unless he can create calcium out of nothing or perform nuclear fission/fusion inside his body, his body should collapse into a pile of saggy skin. It's one thing to move bones around, but it's another to make protruding spikes out of bone.

And I still think Shikamaru should've felt Tayuya up with the shadow hand.
