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!
