Oh my goodness! Can't say I knew much about the actor, but I was so impressed by how he took what was initially a minor phlebotenum-dispensing character and made him into something complex and sympathetic.

His understated disgust in the final ep, it was powerful. It added a necessary ballast to the complex question that the episode, and really the whole series, was dealing with. A lot of that is down to the writers, but the actor gave it real weight.

I'm sad.
