Theory:Doctor Who television discontinuity and plot holes/Smile


 * Nardole acts coldly towards Bill, even though he showed no animosity towards her in the previous episode.
 * I think this is because he knows that the Doctor is planning to go "off-world" and is perhaps simply annoyed with the situation as a whole.


 * Why does the Doctor neglect using his TARDIS to fly straight into the ship in the city? Why run the risk of being attacked by the bots again?
 * He wanted to keep Bill safe. If he flew the TARDIS into the ship then she would almost certainly want to go out with him. He wanted to make sure she stayed well out of the way.
