Divinity Photography: I can't help but point this out...

The Tardis told the Doctor that she had saved around 30 of his control rooms schemes in the tardis in a specific room. 30. 3-0. Now, someone who kinda watches the series or has just stared will say “So?” The reason this is important is because that means there’s at least 30 doctors….

I would agree; however, the Time War changed the rules. 10th Doctor and 11th have said that they could change as many times as needed (10th saying as many, 11th saying he could have 507 regenerations) but in the end, we’ll never know, because as River puts it: “The Doctor lies.”
