Theory:Doctor Who television discontinuity and plot holes/Vincent and the Doctor


 * How does going back to check on van Gogh after looking at the monster-in-the-church painting, and preventing the monster from being included in it, not mess up timelines like in Father's Day? It seemed like a massive screw-with-your-timeline thing to me, hardly excusable by timey-wimey-ness.
 * Unlike Father's Day, at no point does the Doctor cross his own timeline in this story.
 * Why does the Doctor need to hurry Dr Black for an answer of when the picture was painted? The Doctor has a time machine, he can get to Paris any time, he doesn't need to hurry?
 * He's most probably eager to sort Vincent van Gogh out etc, and plus he doesn't want Doctor Black to ramble on with information that he probably mostly already knows.
 * In addition, he probably didn't want to take time away from the museum visitors.
 * He's also a bit rude, and very impatient.
