This was another one of those building-up episodes, mostly dedicated to show how l33t the powers of Medusa are. That’s one thing I rather dislike of shounen-series: it takes ages to get to the good stuff, and the building-up episodes hardly provide anything interesting.
This episode was decent enough, I suppose: we see the identity of the head witch and Maka finally stops angsting over Soul and in the next episode, she and Soul will get some special training in order to power up. I really hope that the creators won’t end up god-moding their characters this way… a common pitfall of these shounen-series is that they power up their lead characters way too much, instead of choosing for the more continuous growth. Claymore is one of the few who actually avoided this one.
