I don't know too, mikono grown so much that I can't see her cracking up unless they further Fudo's conflict. She earned a lot of self-confidence to the point that she even argued against Fudo. Not to mention her
latest saving action. And so far she is the only one that did so among the crew. She is like had stepped up from the Amata and friends level, to a new level, more close to Fudo and Mykage league. Amata and her friends follow each time whatever Fudo tells them to do, as soldiers. What they are. Mikono is starting to take another direction. A direction that will put her in a grey/bad light more an more from now on (my guessing**). That bad side of her could be meant in that way too. Seconding what Zuul was saying.
**my guessing skills have never been so low about an anime than in EVOL.
