Doctor Who: 20 Things You Didn't Know About The Tenth Doctor
9. He REALLY Wasn't Happy With The Eleventh Doctor
The Day of the Doctor celebrated 50 years of Doctor Who by bringing back every previous Doctor, and introducing a brand new one.
In the scene where the Tenth, Eleventh, and War Doctors are all stuck in a room together, they confront each other about their actions during the Time War.
In a seemingly meaningless piece of dialogue, Ten is mildly upset that Eleven has forgotten how many children were on Gallifrey the day he destroyed it.
However, in the novelisation of The Day of the Doctor, things get way more heated.
Ten gets really mad in the book, grabbing Eleven by the coat lapels, "roaring" in his face, and "yanking" his older self around.
It's quite terrifying if you read it, which is probably why it was left off TV.
