Something is up with Rosie in TLD, and her absence from the episode makes no sense at all. When asked about her, John hesitates says that she is ‘’with friends’’. That is a very vague answer, which is odd, as John seems to be pretty open and honest with his therapist. Also, what friends?
Rosie definitely isn’t with Sherlock, as he is drugged and John haven’t seem him for a long time.
Rosie definitely isn’t with either Mrs Hudson or Molly, as they both appear shortly after John’s statement on the above screencap.
What other friends does John have? And where is Rosie really?
“with friends” was also what was said about mary in the acd canon to keep up appearances, so i’m taking this to mean the baby is fake
Charlie Welsborough is a trans lesbian who was planning to come out to her parents when she got back from traveling.
“Travel broadens the mind” is one of the first things we hear her say, on a pre-recorded video. Charlie would like her parents’ minds to be broadened, so that they would accept her rather than meet her with transphobia and homophobia. Charlie recorded this video of herself pre-transition, because she’d like to come out to her parents in person.
Sherlock immediately deduces that Charlie is trans. When he meets the Welsboroughs, he says, “I really am most terribly sorry to hear about your daughter.”
When Sherlock is corrected, he realizes that Charlie isn’t out to her parents yet. Not wanting to posthumously out Charlie, Sherlock doesn’t comment further – especially when he notices the Thatcher shrine and realizes all the misgendering and other forms of transphobia (and homophobia as well) that Charlie would have been exposed to from her parents. This, however, does explain why Sherlock is so petty to the parents. Sherlock hates homophobes and transphobes.
Sherlock describes Charlie’s plan, but doesn’t tell the parents the full story, instead describing Charlie the way the parents knew her. (Sherlock as an unreliable narrator would also fit with the rest of episode, especially if the alibi theory or some form of it turns out to be the explanation for TST.) Sherlock doesn’t explain that Charlie’s “surprise!” (complete with the rainbow across her face – why Charlie is not only trans but also a lesbian) was a plan to come out to her parents.
She went after a John who wasn’t sure about his feelings for his wife by being enigmatic and finding him interesting/attractive and paying attention to him.
And she went after Sherlock by basically being JOHN. Blonde, bad family relationships, cane, suicidal with gun. They had chips together which he WANTED TO DO WITH JOHN KILL ME.
She went after John by seeing him when he felt unseen by Sherlock. She went after Sherlock by needing him when he felt unable to help John.
