So here’s my theory about Janine: she was in on the whole “relationship” ruse.
- In “The Sign of Three,” there is this exchange: “Do you like solving crimes?” / “Is there a vacancy?” And Sherlock nods slightly while looking at John. I think this is where his plan started forming: he must have already found out about her connection to Magnussen during his extensive interviews of the bridal/groom party (if he interviewed the usher and the ring bearer, of course he interviewed the bridesmaids!).
- So, when she asks if there is a vacancy in crimesolving, he considers recruiting her as a partner in this relationship ruse to get into Magnussen’s office.
- “I wish you weren’t…whatever it is you are.” It’s clear that Janine knows that Sherlock isn’t into her in that way. So it makes more sense that she was only acting to fulfill the relationship ruse.
- “So we’re good then?” / “Yeah we’re good.” This sounds suspiciously like they had an arrangement. And it’s a mutually beneficial arrangement: Sherlock gets his image tarnished a bit (to get Magnussen to underestimate him, and also to strengthen the drugs problem), and Janine gets rich from the tabloid tell-alls. Additionally, Janine also gets revenge against Magnussen, who once flicked her eye too.
- And she’s still affectionate with him: I don’t know what duped fiance would still be affectionate with the supposed beloved who just called her a tabloid whore. Another piece of evidence that this was all part of an arrangement (and they can still be sassy with each other).
- Why have a play-act a relationship at all? Why doesn’t she just let Sherlock into Magnussen’s office without the pretend engagement? Because this gives her a cover story, in case she is ever implicated as an accomplice for Sherlock’s breaking and entering.
- So why was Janine angry with him? I think it probably has to do with his very real drug use and the fact that he lied about where he was and what he was doing. She cares for him like a friend, but the drug use was an act of betrayal (like Molly said).
And I also think she did want to play the ruse out and sleep with him, just once, and was disappointed that she didn’t get to.This is a theory I can totally get behind.
THIS IS THE BEST THEORY I HAVE EVER READ
Not to mention that they didn’t meet before the wedding time and Janine seems far too clever to think that Sherlock Holmes of all people would be proposing to her after what couldn’t be more than a month of dating
Another piece of very compelling evidence for this theory: all the lies she told the tabloids about his sexual behavior were flattering. If she were really furious with him, if she really wanted to get revenge on him, she could easily have filled the page space talking about what a LOUSY lay he is. Instead she decides to tell the world he’s a scorching-hot sex machine. He’ll get the irony of course, but to the general public she’s just given his celebrity brand a whole new layer of luster.
Ooh, I like this!!
