Ok so I don’t think it am the only one that was a little dissapointed in this episode. It seems like the doctor and Clara have been a little slow since the entire season. They usually sort the problem out a lot faster. And I keep going back and forth on if I like this doctor or not. He reminds me a lot of the third doctor which I really enjoyed but for some reason I am not getting the same satisfaction. It seems like they were trying to go back to that setup with the doctor working with unit and Osgood possibly taking over as companion or at least joining in battling the master\missy. This would have repaired a lot of the awkwardness we have been getting from the doctor and Clara. But now that this seems off the table I have a plot twist that will fix everything. Clara was telling the truth that she made up her identity but she was actually the master (younger version of missy) and that is why missy chose her. Big paradox changing your own time line but who cares. The doctor and Clara face off after she finds her fob watch.
