Yeah, Episode 13 was wonderful. I've been waiting for a Mako focus episode for a while, and it's nice to see they really delivered on it. I love the big-sister/little-sister vibe that the girls have, and for an episode that I thought was going to be silly, it really delivered on both heart and action. That Heaven/Earth strike the girls did was absolutely wicked, and their finishing poses were badass.
Episode 14 on the other hand was absolutely, unquestionably silly. Ashamee and I watched it last night (it's out, go get it!) and were cracking up the entire time. So many facepalm moments, which I guess is to be expected when Ryuunosuke/ShinkenBlue is involved.
