Time for another speculative theory about the Christmas scene

 (Sherlock meta by kathleenkellly)

Time for another speculative theory… In A Scandal in Belgravia prior to the Christmas scene, suppose Sherlock had been mistakenly informed that Molly had a boyfriend. He was especially agitated during this scene. Now this was probably due to the fact that all these people were in his flat. But maybe there was more to it. Why did he go after Molly here unless there was something that we don’t know about. He seemed so determined to prove that Molly’s present was for her boyfriend that it completely blinded him from the fact that it could be for anyone else (or himself!).

Let’s work through the whole scene. It starts out with Sherlock playing the violin near the window. As others have pointed out, every time Sherlock is expecting Molly at Baker St., he is near or looking out the window prior to her arrival. In this scene, it cuts away right after he steps toward the window and shows the outside of the building just as a cab drives by. I watched this very closely and it appears that he looks out just as it cuts away. In the previous scene, Sherlock is playing the violin and watches out the window as Mycroft leaves so it would make sense that in this scene he would be playing as he watches for as someone arrives. Playing the violin would give him an excuse to casually walk around and look out the window for Molly without anyone noticing. I’m guessing this party is just a casual, drop-by-whenever type of get-together. We know that Molly was invited because no one was surprised to see her, so Sherlock would have known to expect her. He finishes playing his song and proceeds with trying to figure out Jeanette’s name in his slightly annoyed mood (which gets worse when Molly arrives), not caring about her or John’s feelings. In fact, he seems to want to ruin everyone’s relationships as he later informs Lestrade that his wife is sleeping with a p.e. teacher and that John’s sister is still drinking, again all without remorse.

Molly arrives all dressed up, bearing gifts. “Oh, dear Lord.” Now this comment can be taken different ways. I think it’s due to her fancy appearance. Look at his eyes when he sees her walk in. They’re wide open and he stares at her for a minute. He wasn’t expecting her to be so dressed up and he’s probably never seen her like this before, since he mostly sees her at work. He says it sarcastically, but I think he is hiding his genuine surprise. After Molly walks in, Sherlock avoids looking at her. She takes off her coat with everyone in awe. She tries to make eye contact with Sherlock, but he busies himself with the computer, deliberately trying to distract himself. He can’t help but listen to the conversation though and add his biting remarks.

Molly makes conversation with everyone. She makes the joke to Mrs. Hudson about doing post-mortems. “Don’t make jokes, Molly” Sherlock says almost affectionately. I think Sherlock liked this joke. He couldn’t help commenting. He has a morbid sense of humor just like Molly. To me the subtext here is “I appreciate the joke but these people don’t, so it’s probably not a good idea”. We find out that Sherlock chats with Molly, possibly as they work together at Barts, and has told her about everyone’s holiday plans. She finally gets Sherlock to look over at her briefly by teasing about his complaining.

Sherlock proceeds to get crankier until he finally can’t stand it anymore. He has to find out who Molly’s boyfriend is. He has been thinking about it since she walked in and has now reached the breaking point. He picks up the present to peek at the label, but not before showing off a little. His deductions seem like rather a stretch unless he had heard something about a possible boyfriend. He jumps to some pretty hasty conclusions (she’s serious about him? long-term hopes?… getting a little ahead of ourselves aren’t we, Sherlock?). He thinks the reason she’s dressed up is because she’s seeing him later. This would explain why he’s gotten more agitated since she’s arrived. His jealousy has manifested itself as annoyance with everyone and trying to prove he is right.

Sherlock has a reason to worry about Molly having a boyfriend. The last guy Molly dated was Moriarty so Sherlock is probably feeling protective of her knowing what he does now. I wonder if he’s told Molly who Jim from I.T. really is. Either way, he has now met Moriarty and knows this same man went out with Molly. It would seem natural that he would worry about her since they work together often.

Sherlock’s focus on Molly’s boyfriend causes him to be wrong. His jealousy has gotten in the way of his deductions and causes him to hurt her. For the first time we see his feelings get in the way of his reasoning, the very thing he tries to avoid.

Sherlock is shocked. You can see it on his face. Not only is he wrong, but even worse he has hurt Molly. What started out as friendly teasing ended up going horribly wrong. She calls him out on the awful things he says. He tries to walk away, but can’t. Whether he was aware of it before or not, Sherlock realizes now that he cares for Molly and that he really screwed up. He apologizes and kisses her on the cheek to the shock of everyone else. His phone goes off and he gets distracted with Irene’s present still feeling awful. John tries joking with him about about the number of texts he’s gotten, but he’s not in the mood. He sets Molly’s present on his desk and we are left to guess what it could be. I also wonder what would have happened had his phone not gone off…

Later on in the episode Molly asks him about Irene’s phone: “Is it your girlfriend’s?”. “You think she’s my girlfriend because I’m x-raying her possessions.” Molly says “well, we all do silly things”. I think Molly is referring to how he deduced she had a boyfriend because of how she wrapped a present. They were both trying to figure out if the other was seeing someone or not and made hasty deductions. They are both interested in each other’s relationship status.

This is all before the big breakthrough Sherlock has with Molly in TRF, but I think it’s where their relationship really starts to change. Sherlock, who has never cared about what he says to others, including everyone else he taunted at Christmas, realizes Molly is different. He didn’t like how he felt after he hurt Molly and I think at this moment he resolves to treat her better. And Molly knows that she can stand up for herself and challenges Sherlock to be the better man that she knows he can be.
