how kakashi re awakened ms

[kaddie9]

he probably was at obito's and rin's graves and was grieving over them and his body could handle activating it at that time instead of just passing out like he did when he first awakened it.

Nah he just didnt know how to activate it in part one and he trained it ^^

 

[Deception..]

im not sure if always knew he had ms or not but i do believe in part the never had the chakra reserves to use it
