Theory:Doctor Who television discontinuity and plot holes/The Husbands of River Song


 * In The Time of Angels, River claims that although she has pictures of all the Doctor's faces, she doesn't know their right order. Silence in the Library supports this claim, showing River asking to the Tenth Doctor about the Crash of the Byzantium. However, the pictures of the Doctor River gave to Ramone is in perfect order. Is it just a coincidence?
 * Production wise, the props manager didn't know of that line and placed them in the order they recognized. In-universe, this episodes takes place sometime after Angels, so River may have found the number of some of the Doctors and placed Ten were she thought he would be, and was correct by mere happenstance.
