On shooting the sex scene: "It was strange for me having known [Williams] since she was 11 or 12 years old and being asked to play out a scene like that. That discomfort I had initially seemed to have been shared by quite a lot of people who have watched that episode, too. But I found the subsequent conversation actually really quite interesting. What that scene ended up doing was forcing people to confront their own hypocrisy in a way.
I think the root cause of that unease and discomfort in a lot of viewers is because they feel like they've seen her grow up on screen. That's something that happens to us all — we all start off young and then the majority of us start having sex and we're all perfectly capable to finding that journey out for ourselves, but we still find it difficult to watch someone else take that journey, say, on a TV screen."
