I think this episode really showcases how TALL Karen and Matt are. More than the first two episodes this series.
Doctor Who Confidential mentioned that Karen is 5' 11". The outfit she is wearing in this episode makes her look lanky compared to the night clothes of the second episode.
LOL, me too. Though I was talking to someone in the UK about it. I was told essentially "You won't understand, it's a UK thing with the Spitfires..." I said "You're right"
