She's still reeling from Sherlock's words when she extends the offer to Jim. Still fretting herself silly over that little comment that only serves to wound her pride more than anything else. He isn't gay. He isn't! She's almost…mostly…50% sure of it! That's why she asks him really, extending that friendly invitation with tight lipped apprehension.
"The new Glee episode airs tonight, if you fancy coming over to watch it? I've got wine, and we could order pizza…" She's not the most convincing of saleswomen, but she's sincere in her offer, as she shuffles there on the spot like a schoolgirl, waiting for an answer that will either put her mind at rest or condemn her to another circle of hell entirely.
"Sure, I'd love to." That accented lilt is enough to lay waste to her fears, that little voice sending blistering warmth in currents throughout her chest. She's smitten and he knows it, does it on purpose really, to keep picking away at her resolve and in turn, Sherlock's too. She's not terrible company either, he can concede, but she's not his type, she's just a means to an end and a way to pass the time. A pawn in his game on his quest to reclaim the crown and throne so rightfully his, as the crowned prince of criminal ingenuity.
Molly of course, the naive little thing, is oblivious to this when she bounces off with a spring in her step. A better man might've felt guilty for stringing her along, but Jim thinks he's paying enough of a price by having to sit through an entire hour of butchered songs for a second time. In actuality, that's why he does what he does, arriving on her doorstep later that evening, with his dear friend Sebastian Moran in tow. The look on the pathologist's face is priceless, that polite but thinly veiled look of anguish and disappointment all rolled into one tense smile.
His logic is quite simple, he needs his favourite marksman there should the music become too much. Just so a friendly face can put a bullet between his eyes and spare him the horror of another agonising moment of mind-numbing drivel. If he has to suffer, so should the sniper, - the fact it bothers Molly however, is merely an added bonus. He has to be the only person that's ever brought a plus one to a date night before, or at least the only person ballsy enough to flat out lie and pretend he didn't even know that's what this was.
It's wonderful to watch though, when she ushers them both inside with that nervous little twitch he's only ever seen on her in Holmes' company. It's empowering really, watching her squirm and choke down her own protest, to try and hold it together when he's so clearly insulted her. It gets better still, when he settles into that sofa, with Seb at his side, only to pat that little spot between them with the patronising grace of a man who's asking for a smack.
To her credit, she refrains, although the way she's getting through that bottle of wine speaks volumes to them both. Settling in between the sandwich of unconventional company, it's at the bottom of her glass that Molly finds solace, the exchange of amused glances escaping her notice as she tries, somewhat harder than usual, to entomb herself in the lyrical fallacy of Glee - while her two dinner guests make themselves a little too at home.
This isn't what date nights are supposed to be.
