Despite what Mummy believes will happen, Mycroft is not the first person who offers Sherlock a cigarette.

'Want a cigarette?'

Sherlock turns his head and squints at the young man next to him with his icy eyes.

'Yes,' a 20 year old Sherlock answers. He is handed a cigarette and sticks it in his mouth. The man offers to light it and Sherlock watches intensly as the man makes the tip glow orange with a lit match.

The man is older than Sherlock by a few years with light brown, slicked back hair, and bright blue eyes. He's from a wealthy family. Sherlock can tell by the man's jacket.

'What's your name then?' the man asks and Sherlock expertly manages not to cough after the first drag.

The jacket is new, modern and very fashionable. Likely bought very recently, indicating that the man is either good at saving money, or rich. The right sleeve is covered in graphite smudges, as if dragged over several papers of graphite notes. Therefore hardworking. A man who gives his studies his all.

There's a clock strapped tightly around the man's wrist. It's well cared for and likely thought of often. A gift from a lover, perhaps.

'Sherlock Holmes.' Sherlock introduces himself with his deep voice and offers his hand. The man takes it firmly. 'Victor Trevor.' Tight grip, so probably confident.

At his next drag, Sherlock can't help the little cough that forces itself out of his throat. Trevor grins.

'First time you've smoked Holmes?'

Sherlock clears his throat against his hand, and offers Trevor a little smile.

'Please, call me Sherlock.'
