Okay I was an idiot and forgot to make a review/summary for the last episode. Sorry. Okay this episode is the first of two. The Doctor and Clara travel to future Scotland. Ghosts were trying to kill people so they could find something in the town that was flooded. Clara and two of the people on the underwater station were left behind when the Doctor went into the past, with 2 other members, to try and find what the ghosts were looking for. The episode ended with the Doctor becoming one of the ghosts. I believe I had stated in an update that the episode was really cool. It was, the sonic sunglasses are still weird though. I'm trying to wrap my head around them. I can't wait to see what happens in the next episode. I hate cliff hangers.
