Maius Intra Qua Extra

Well, even if the Doctor knew the rules (and I thought the rules were that he could take it if Clara agreed to give it to him), I still would expect him to make at least an effort to find a loophole that he could use to take it from her, especially from Clara.

There's a difference between Nine's "Put her on a slow heat and let it simmer" about Jackie and Twelve's repeated "Your face is too wide!", the first one is just alien but the second one is rude.

I don't particularly like Twelve being as rude as he is, but I've been fine with it, writing it off as a quirk of this incarnation. After all, Six was often just as rude, with his many offhand comments about Peri being fat. Twelve seems to have lost a lot of that, though. It seems to have turned into social awkwardness rather than outright rudeness, such as his inability to tell when he should show empathy or apologize. I suppose that's supposed to be part of the "Clara making him a better man" theme.

As a side note, your comment about Twelve being rude reminded me of Ten's "And you, Rose Tyler! Fat lot of good you were! You gave up on me! Oh, that's rude." Though it was a great line, I never thought that Ten was being rude when he said that. Blunt, yes, but not rude. Of course, he was rude at other times, but that particular time never rang true for me.
