‘In Memoria' (written by Jesse Armstrong). You know when you have an argument, and everyone's fantasised about being able to rewind and go, ‘Here's what you said earlier,' or ‘Look how you embarrassed me' or what have you? Well, this is set in a world where everybody has got the ability to do that--you've got the equivalent of Sky+ for your head, so that you can rewind and replay your visual feed.
