you know what also hurts me? Eurus is described as a ‘genius defying century’ by Mycroft, and we obviously get it by looking at her magnificent ways of hypnotizing. but it really hurts me when I understand that she would make much more impaction on the world if she was actually out of prison, if she was living the normal life. some way this was taken away from her just because she once went the wrong way. I perfectly picture her as a scientist, for example, because I do feel like it’s something that interests her more than anything else. Mycroft likes being empowered, Sherlock loves the feeling of the game, that’s why he’s solving crimes, and Eurus really likes exploring. we could only imagine what exactly would she explore if she was actually out of prison. if Eurus inititally wouldn’t like to kill Sherlock (because she wanted him to be her only friend and jealosy made her hate him), she could have been a really nice, though manipulative little sister she was always meant to be. we can only imagine who would she be if she wasn’t... you know, the girl in the plane. there’s really much controversy between Eurus and Sherlock, but I really believe that she just wanted some attention. and wishes of killing him are just her inner self showing some weird ways of deciding this loneliness problems. I guess she always was that kind of person who would take their revenge at some point (as well as Moriarty, who did the same with Carl Powers, though the story is really different there). she didn’t want to put up with Victor, so she decided to not only test Sherlock, but also make him play with her. that’s the thing: if she wasn’t alone, she would be a lot more different person.
