Woah. You know what? I'm not even going to bother with an attempt at a real introduction here, because the last five minutes of the episode were pretty heavy and that's what I really want to talk about.
This episode wasn't what I thought it would be; instead, it was a fun, madcap adventure which brought about the return of Madame Vastra, Jenny and Strax.
As much as I hate to admit it, the second half of "Doctor Who" Season 7 isn't going as well as I hoped it would, and the latest episode was about to go into the pile of disappointing episodes if it wasn't for a few significant scenes involving Clara.
