The Eleventh Doctor and Rory have a boy’s night out as they go to a coronation in a city made of glass. While fun, the problem with this story is that we know who the main villain is going to be before we even start. It kind of removes the mystery element that comes with a murder mystery story. I also felt like some story elements didn’t land very well, like the fight with the Zygons and the conversations between Rory and the prince. It is still a good story, however, as the overall writing feels very natural and it gives us quite a bit of insight in Rory.
