A rubbish brown coat (not the legendary Tennant overcoat, sadly, that would have been funny) is a paper-thin disguise for a Doctor who is a bit of a rubbish caretaker. While he endangers Coal Hill School to fire Jimmy Vee into space, Clara makes some rubbish attempts to keep her two worlds separate. The episode? Not at all rubbish. But it's time to talk about Clara, and how the Doctor and showrunner are treating her.
