I mean seriously, look at the accent lighting behind the bones!
A couple of comments on this episode: he just happens to have a photographic memory, and he just happens to know romany-greek, and there just happened to be someone else who did present to transcribe the witch's last words? A few too many things that are convenient to the plot, but OK.
And that nurse at the end was extremely condescending. Not a very professional healthcare… professional.
I love the big demon thingy though, and how we only ever see him out of focus. That I can get behind :)
