Theory:Doctor Who television discontinuity and plot holes/The Doctor Falls

From Tardis Wiki, the free Doctor Who reference
  • How were the rifles upgrades? And if every rifles was upgraded, so why wasn't Bill destroyed when she was shot at by accident?
The rifles weren't upgraded. It was just Nardole hacking the spaceship and exploding parts of it. The rifle shot was a deception, to fool Cybermen into believing humans have serious weapons.
  • Did something happen to the programming of the Cybermen, cause, I thought they only went after "humans" with 2 hearts!
