We give her props for calling the Doctor out and leaving him lost for words most times. Her quick wit and cheeky sense of humour makes for an entertaining partnership to a still-recovering-from-the-Ponds Doctor. Her comedic timing is something the Doctor needs, if not to slowly get back to his normal look-at-me-being-brilliant-Ponds self, but to at least try and get back a bit of his silliness. We gave her full credit for "clever" back in Asylum of the Daleks, but "cheeky" has already been done before (remember Donna? well, she doesn't).
