I just want take a moment to appreciate the fact that Doctor Who finally got a female writer of an episode. For the first time since Season 4 (2008). Catherine Tregenna also previously wrote for Torchwood.

And I believe she and Helen Raynor are the only female writers New Who has had? And something like the fifth female Doctor Who writer ever.

(for the record, Torchwood had 5 through it’s much shorter run,)
