The highlight of the episode was seeing Clara talking to the Doctor has a child about "Fear". It got me thinking, I wonder how many parents are going to use the "Fear is a Superpower" speech to their kids. I know if I ever have kids, I will. We also find out that the barn that the child Doctor was sleeping in was the same barn that the War Doctor went to, to end the Time War. That is what I love about Dr Who. It's a show so rich in history, that we have a scene that connects Williams Hartnell to Peter Capaldi. I was literally on the edge of my seat wanting more.
My only problems about the episode is first, what was under the sheets in the boys bed and secondly how did the Tardis get to Gallifrey. I don't buy that hooking the Tardis up to Clara could bypass the time lock. By that rational then, the Doctor could hook himself up to theTardis and get to Gallifrey anytime he wants to. Then again, maybe he will do that in the near future. A Whoivan can only dream of an episode set on Gallifrey.
This was by far the best episode of the season and one of Moffat's best work on Dr Who. I give "Listen" 4.5 Tardis's out of 5. I think I will go watch it again before the new one airs.
