Theory:Doctor Who television discontinuity and plot holes/A Town Called Mercy


 * The Gunslinger arrives a lot faster the first time someone crosses the barrier than he does the second time.
 * So? Does it take you the exact same time to go from your house to the shop every single time? No, he was just travelling at different speeds.


 * How did Jex build street lamps and working lightbulbs with 1870 materials? His ship doesn't look big enough to hold them.
 * The Doctor states that they could build a spaceship from something and moss. So I'm sure he could create street lamps with metal scraps and wood.


 * It's never explained why his ship has so much security.
 * Because he obviously doesn't want someone to be able to find out the true horrors of what he did.


 * Why try and force Amy to go with him at gunpoint? If the gunslinger was already distracted by the Doctor, and she was already shown to be sympathetic to him, did he really belive she would disagree?
 * Because she could fight back? If he wasn't going along with the plan, then Amy would try to stop him.


 * The hole that the gunslinger shot in the Stetson looks like a regular bullet hole, but his gun fires incredibly powerful energy blasts; it should have incinerated the hat.
 * He might be able to shoot normal bullets as well.


 * And if he's such a good shot, is it really likely he would hit Rory while trying to shoot the Marshal (thinking he's Jex), as there is a reasoanably large distance between them?
 * It said on his screen '89% chance of hitting' or something, so he doesn't have perfect aim. Plus they were moving, and Rory was behind him, so he just shot too late.


 * Throughout the story, the characters wield Colt Singel Action Army Revolvers, but the story is set in 1870, and that revolver wasn't invented till 1872.
 * History in the Whoniverse didn't go the same way it did in the real universe, so that kind of revolver was probably just invented a few years early.
