Lestrade suppressed a smirk as Sherlock pinned a young officer with that cold stare that positively screamed "Go ahead and ask. I dare you". Considering who the consulting detective bore a strong resemblance to, it was quite understandable that the young man had nearly pissed his pants as he swallowed back the obvious question and backed off in search of something to do, preferably as far away from Sherlock as he could get.

He'd been pinned with that exact glare back when a certain young man who'd been high at the time had tromped over to the police tape and started giving him unsolicited advice as to how to solve the murder he was investigating, insulting his intelligence all the while. Of course, he'd been standing there gawping at the young man who'd interrupted him when he had been about to take what in his opinion back then had been a much needed smoke break at the time. He'd nearly earned Sherlock's eternal enmity that very night by saying the name which had been verboten to utter in his presence since 1993. The name of an individual who had caused Sherlock Holmes to receive a number of sideways looks and outright stares for most of his life, especially as he grew older due to the resemblance between the two.

You could call him just about any and every name in the book, you could accuse him of having had something to do with the body he'd found and chose to call and report and, after making a couple of embarrassing observations that would have your colleagues staring at you and snickering behind your back, he would brush it all off as nothing. Mention Khan Noonian Singh's name within the range of his almost preternatural hearing however...

Sherlock had told him the story once, and it all boiled down to what Mummy wanted, Mummy got. Even if it was an embryo that was left over from a certain genetic experiment that she may or may not have had a hand in causing to come to fruition back in the 1960s.

Every day since he'd heard the tale of the origins of one Sherlock Holmes, he thanked his lucky stars that Sherlock was content to wander around London solving crimes. If he had decided to follow in the footsteps of his more infamous older brother, the world would quite likely have been screwed.

Considering the fact that Sherlock's other older brother had been born as a result of that same genetic experiment that had created Khan and his ilk, and the fact that the elder Holmes was basically in control of Britain's government, it was entirely possible that the world was screwed anyways.
