Sir Arthur Conan Doyle, Steve Moffat, Mark Gatiss own Sherlock and his realm. I just own my computer,my version of Openoffice, and my sick fantasies. English is not my native language, please forgive the mistakes and the typos.

Anonymous on Tumblr proposed to Ilovesunshine93 a prompt ("a Cabin Pressure x Sherlock crossover where Sherlock stumbles in on Martin flirting with Molly and he gets jealous"),and since she doesn't listen to cabin Pressure, and I'm in love with that radio show, I decided to adopt this prompt. Definitely Sherlolly, dear Mr Crieff is only a supporting character here.

Sherlock Holmes approached the morgue's doors with the sprint in his step that only an apparently unsolvable triple homicide could cause. He flung the doors open with a theatrical gesture, when the sound of two well-known voices reached his ears. The first was Molly's: bright,honest...and the other had a distinctive nervous tone that gave his owner away immediately. His half brother, Martin Crieff,whose existence he had accidentally discovered during his "death",was in the morgue (his morgue) with his pathologist. The thing that was really atrocious was that they were giggling...he had to stop it. None should laugh in such a place,with his Molly...but him. The fact that she didn't know that she was his, was irrelevant.

He glared at them, but they were so engrossed in their laughter, that they didn't notice his entrance. Sherlock knew that it was time for drastic measures, and clearing his throat, he approached them from behind.

"She's not interested in you, you know..." his deep voice startled both Molly and Martin, and the captain let out a sharp cry. "Sherlock! I'm- I'm not intere-Wh-what are you doing here?!" he stuttered, clearly agitated.

"Well, I think I may turn the question to you. What are you doing here, Mr Crieff?"

"I-I called you an hour ago, and-"

"I don't answer to phone calls. Go on"

"That's why I sent you a text, to tell you that I would come here because I had some errands to run a few blocks from here..."

Sherlock took out of his pocket his cellphone: a missed call and a new text were effectively signaled on the display. "This doesn't explain why you were here, trying to flirt with my pathologist...like I already said, she's not interested. You, on the other way...".

"I asked him to wait for you here with me...we were simply having a chat, weren't we, Martin?". Molly glared at Sherlock and then winked at Martin, and the captain blushed to the roots of his red hair.

"Ye-yes, we were simply talking!" he exclaimed, a bit too enthusiastically, and the frown on Sherlock's face deepened. Thankfully Martin's phone rang, and the pilot sighed. "I'm sorry, Molly, but I remembered that I have to pick up Arthur in...ten minutes, I'm already late! So, we are ok for later? Seven o'clock, here? I'll be the one with the funny hat!" he joked, but Sherlock's glare made him retreat quickly towards the door.

"Yes, of course. See you later, Martin!" she waved him goodbye, and when she was sure that Martin was not in the room anymore, she turned to Sherlock, her hands on her hips, and a fierce expression on her face.

"What's the matter with you?!" she accused, and for a moment Sherlock was at loss. Yes, what was the matter with him? How could he be feel threatened by his broke half-brother, the captain of a failing airline, with serious self-esteem issues? And why was he feeling such a discomfort at the idea that he was flirting with Molly?

"I shouldn't tell you, but Martin was here also to ask for my help to search for a Christmas gift for you...he really admires you, you know? You could treat him better, he's your brother after all!" Molly scolded him, and Sherlock sighed. "I always miss something..." he thought, with a strange feeling of relief. Captain Martin Crieff wasn't blushing because he was interested in her, but simply because he feared he would discover his ideas for his Christmas present.

"I will try..." he muttered, and she smiled with satisfaction at his promise. "So, you're here for those three bodies, aren't you? Let's take a look!"

Soon, he would have to question himself about his pathologist. For now, he had a pathologist to follow, and a killer to catch.
