Behind the scenes
- Though the joke would have been obvious to the original British audience, it likely would have flown over the heads of audiences elsewhere. TENA Lady is a product to help control incontinence — in essence, adult diapers.
- It's contextually unclear whether Clara was referring to the school secretary previously seen at the start of Into the Dalek, or another one.
