Corrected entry: We know the episode takes place on 23 November, 1963 because the first episode of Doctor Who is about to come on TV when Ace leaves the room. JFK was assassinated less than 24 hours ago, and nobody seems to be affected. Granted, the military characters have other things on their minds, but none of the civilians wear black armbands or even mention that the biggest news story of the year that just happened.Captain Defenestrator
Corrected entry: The events of this episode take place in Nov 1963, the same time as "An Unearthly Child." However, the schoolchildren are now wearing uniforms and the full name of the school on the sign is Coal Hill Road Shoreditch Secondary School instead of merely Coal Hill School.
Corrected entry: When Ace is yelling at Mike for being a stinking dirty scumbag (the second time), she's supposed to be very angry. However, it's plainly clear that she's doing her best not to laugh. Near the end of the scene, she has a grin breaking through, and you can see her actually smirking as she runs off screen.Matty W
