Sherlock isn't sure why he agrees to meet Jim at the club.
He supposes it's 37% curiosity, 15% death wish, 11% compromise, 17% anger and 20% human error. The urge to solve the puzzle, the thrill of the game, the constant threat of death hanging over his head – he finds it all invigorating.
In the sea of writhing bodies, bad club music and disco lights, he finds Jim. His 'Jim from IT' persona hides him perfectly among the clubbers, and Sherlock barely notices when a new body begins to grind against his own.
"Didn't think you'd actually come." Jim whispers, drawing out the last word for added effect.
Sherlock groans. "I never break my promises."
"Good." Jim takes Sherlock by the hand, leading him through the crowd and to the bar. Genius, Sherlock thinks. We'll just be two strangers flirting there. No one will suspect we're a consulting criminal and detective.
Jim orders some fruity drink Sherlock's never heard of. "I have a little proposition to discuss with you," he says, casually. "I think we can be… Mutually beneficial to each other."
Sherlock leans on the bar. "Do tell."
"I'll solve cases for you. Or rather, give you information to solve cases, -"
"Your cases, I assume."
Jim smiles, his eyes full of menace. "Clever boy. Yes, 'my' cases - or rather – my client's cases. I'll give you everything you need to solve them, and go give me you."
Sherlock raises an eyebrow, not fully understanding what Jim means.
"Oh, Sherly, don't play coy. You know exactly what I mean." Moriarty winks.
Sherlock bites his lip. The offer is tempting, of course, but there are other, more important matters to consider. Mycroft, John, and all the Yarders will have to be sorted out. He'll need explanations, excuses, precautions – all to ensure total secrecy and safety. He can't go rushing into it. "I'll think about it," he responds, standing up and walking away without waiting for Jim's word.
Jim spins around on his barstool. "Don't take too long. Or else…" he laughs. "You get the point."
