Oh man I have thoughts about this. First of all, it’s understandable that maid-of-honor Janine isn’t the godmother given what happened in HLV, but Molly wasn’t a bridesmaid either, and there were two others. So how did Molly get this ‘promotion’ of sorts?
I know there’s a popular headcanon that Mary and Molly are besties – and I’d LOVE to see those two actresses in their own show together – but there’s nothing in this show to support a friendship between their characters.
In HLV, after the shooting, we see Molly (IRL, not MP), only twice – the boltholes convo, and the very end when she sees Miss Me on the TV. She never interacts with Mary and John.
So yeah, maybe she doesn’t know Mary shot Sherlock. Except…Mrs. Hudson does. She was there for the domestic. And Hudders and Molly and Greg always call each other with concerns about Sherlock and John. For the love, if Molly and Hudders had a phone call worrying about Sherlock reading telegrams, surely they talked about the fact that his best friends wife fucking shot him.
(Greg, on the other hand, Hudders may not have informed, because that would be turning Mary over to the police, which she’d prob feel was none of her business.)
But I mean…I can’t imagine Hudders didn’t tell Molly. Hudders has a dark past with an abusive ex. Think about what she saw in that domestic scene. What she heard.
She had to tell someone. She’s worried. And frankly, it makes sense that she’d turn to the woman who helped Sherlock the last time he was in this much danger.
And so we’re supposed to believe Molly learned Mary shot Sherlock, nearly killed him, then tried to shoot him again…and she’s OVER it?? Happily accepting the role as godmother of this child? Molly didn’t get a twisted surgery explanation and a fake forgiveness. There’s no fucking way Molly just…doesn’t care.
My prediction is the episode will start off appearing as though Molly never found out about the shooting. But she knows, and what she does with that knowledge, along with whatever weird shit Jim (dead or alive) has in store for her, is going to be a big part of her plot this series.
