No idea what's happening to Clara but omg, this was the BEST episode this season! It was original, it was funny, it was creepy! Definitely a classic. I kept on giggling as the TARDIS shrank and shrank and shrank, . The Addams Family moment was just so adorable too. The sledgehammer, the 2DIS, . SO many funny moments and lines. There were awesome scary moments too and I really liked that. It was also nice to have monsters that were completely bad for a change and have The Doctor deal with them accordingly.

Okay, like I said, I am finding Clara more interesting this season, with her doing more than usual. However, with this episode, I'm starting to think Peter is either injured or the higher ups don't want to give him a coronary because his action scenes compared to Chris, David and Matt are quite few and far between. Either way, this episode is definitely in my top faves. I still haven't figured Peter's Doctor out yet but if they continue doing writing like this, I don't mind taking my time.
