We Don’t Know (it depends on the weather)
If it has to do with paperwork then it’s Kat’s! She takes care of all those office things that most people don’t like but she thinks are wonderful! We know that liking paperwork is a little unusual but so is Kat! Kat does a bit of everything at the moment so who knows where she may pop up next!
Do what I do. Hold on tight and pretend it’s a plan!- The Doctor, Doctor Who, season 7 Christmas Special
