I'm sure this was discussed when it was out last year on BBC but I've only just watched this now ... and I'm completely disturbed and need to discuss!!!
HOW terrifying?! A new level of scary and Mark gatiss is such a brilliant writer ... ive been jumpy all day thinking about creepy Eurus.
One question - how did the little girl on the plane fit in to the final episode? Was she real Kentucky a construct of Eurus?
