A very fun little runaround.

There's not really much if any plot here, but it gets you into the mindset of Eleven at this point, and gives it a firm timeline placement which is really nice to have.

Now that I think about it, this era really is some unexplored ground, on TV you just go straight from "Where's Clara" to finding her, filling in the gap here is really nice and is a fun way to set this era apart right from the off.

Also of course, Dudman's impression is spectacular.
