With regards to the ending, I got literal chills when the TARDIS appeared. I really thought woah we’re gonna get the Paternoster gang travelling through space and time with 8 trying to find Vastra, then for the post credits scene just to… have them locate her and she’s already back at Paternoster!? It’s like… they implied a really intriguing plot then just instantly went “oh it happened off screen” and I’m sad.
