This was one of the better episodes of the season, but my complaint about last week's episode is the same complaint here. We're no closer to finding out who/what Clara really is than we were after Asylum of the Daleks or The Snowman. We just know it's "complicated". Here's an episode where we have the entire gang back together and it does seem like Clara forgot about the revelations from last week, and no one even mentioned it.
As for this episode, I love Vastra, Jenny, and Strax. I'm glad they are featured time and again. This was a fun episode and reminded me of fun episodes from throughout the series. I just wish this "arc" would be addressed other than "It's complicated".
