Off-switch

I do think the Doctor rather LIKED Courtney, sensing a kindred Disruptive Influence spirit--the way he lit up at that term did make me laugh. But ugh, oh, the choices of Good and Bad students was unfortunate, and while I understand the Doctor is assuming Danny can't be a maths teacher because he's a soldier (bad enough), it came off awfully to me like judging someone as non-intellectual for racist reasons. There was a LOT of cringe-worthy stuff in this episode, and I hated having Clara be "torn" between the Doctor and Danny. They both come off quite bad because of it, although I did think the scene where Danny calls him an officer and rakes him for it was very well-done.
