Well, I can hardly find how it would be possible to forget what happened in the previous 10 episodes, but still. They really made a recap episode, to sum up what previously happened. They focused on how GS became... himself, then the meeting with the 3 others (no introduction of the Priestess at all). Finally, we get to watch the Water Town events (without Sword Maiden's apparition, argh) and they left us at the end of Episode 10. So far a non-necessary episode, which acts as a break before the very awaited Globlin Lord arc. Anyway, it just delayed the next episode and increases the hype! Now we can only expect that they give the show a powerful and bloody animation, 'cause it has to be !
