Shy, Cute but Arse Kicker

3. Flustered because of Molly's behaviour

It was no secret to anyone that Molly was utterly and desperately in love with Sherlock Holmes. Poor thing. So, it was always a great pleasure for her to welcome the Detective in her lab. Well, almost always a pleasure, since he had brought his girlfriend with him.

Foremost, the scientist had thought he would behave as usual: cold, distant, barely listening to anyone, focused on the task at once. And, if Molly wasn't a bad person, she still was a human being, and she was deeply jealous of the one who had succeeded where she had failed. Failed numerous times. Then she was looking forward for this girlfriend to be rejected like the others while the genius was deducing. And Molly was a bit ashamed about this desire, but, again, she wasn't perfect.

She had been confused when she saw him take a seat for the girl, who was now able to sit just next to him, and kiss her head before sitting himself in front of the microscope. When the young woman had started wriggling on her seat looking unsurely around her, Molly had been totally dismayed to hear Sherlock warmly saying

"Don't worry kitty, it won't be long, I just need to take a look at this before we get home, ok?"

And then reaching for her hand and bringing it to his mouth to kiss it soothingly.

If gaze could kill, Sherlock's girlfriend would be very, very dead. How did she go about it? She wasn't a top model and she didn't seem to be brilliant, otherwise she would be helping the Detective solving the case instead of being a nuisance for him. Why did he bring her if she was perfectly useless? Why was he so gentle, and caring, and tender, and delicate with her? How was it even possible to associate all these adjectives with Sherlock in the same sentence?! She must have drug him, there's no other way. Sherlock must be high to coo at her like this. She just looked deeply pathetic, squirming like this, selfishly keeping the man from his work. Drowned in her jealousy, Molly almost jumped out of her skin when she heard the deep and slightly angry Sherlock's voice talking to her

"Molly, if you want us to stay, well... "friends", and if you want me to keep coming to your lab to do my researches, stop at once glaring to Y/N like you're doing. She's shy and I can't stand someone making her feel uncomfortable, even more if it is done in purpose... Don't make me ask twice or I may become aggressive."

He had said all this without looking up from the microscope and still holding Y/N's hand in his, adding a new kiss on her knuckles at the end of the speech. Y/N, highly confused, had turned her gazed from Sherlock to Molly. She had been amazed watching Sherlock flying to her rescue, and she now was deeply embarrassed to confront Molly's jealousy. Embarrassed at first, because, the scientist could feel the challenge she was sending her now. Sherlock was her and her only; if Molly wanted to argue about that, she could always (or again) try her luck. But she would face the one who had been able to make Sherlock Holmes, the highly functioning sociopath, cooing. And Molly wasn't ready for that.

Mollymuttered some excuses and left the room, promising herself she would never fallso low again.
