I happened upon this rather by chance and then it struck me as highly interesting. Here we see Eurus’s room in the very moment she sets fire to Musgrave Hall, i.e. this happens shortly before she is removed to an institution, right?
According to what we are told this is the room of a 5- or 6-year-old “era-defining genius, beyond Newton”. A girl who taught her older brother to play the violin. Who was “aware of truths beyond the normal scope”. Whose “abilities were professionally assessed more than once”.
So what would we expect to find? Books, for sure. Maps. Scientific equipment. Maybe an early personal computer. A violin, for heaven’s sake!
If she had been professionally assessed more than once as Mycroft says, the experts would surely have told her parents how to promote her skills and support her thirst for knowledge. And there would have been evidence in her room because this is the moment before she leaves.
But what we see is a very ordinary room: a blackboard, a doll’s house, stuffed animals, a bedspread with stars on it, plastic boxes with toys - nothing in this room does speak of the extraordinary abilities of Eurus, it does not reflect what we are told about her in any way. What we see is a lonely little girl drawing violent pictures of her older brother, playing with matches.
So, again, we have the choice between sloppy set design and EMP? Eurus = Sherlock? Would love to hear your thoughts.
