Sure, why not

You consider Vladimir's offer. It's not entirely unreasonable, although it would require some work by you. You could just use your mind control on Vladimir, but you think it might be an better solution to just come to a mutual understanding with a mafia boss. At least from what you know, their word is bond and you'll be able to give Daria some peace of mind.

"Sure, why the hell not," you say.

Vladimir looks unimpressed and he proceeds to stand slowly. You back up a little in case he's going to try to wrestle the gun from you. When he's standing, Vladimir waves dismissively to someone behind you, and you hear footsteps moving away. It's then that you realize that 1 or more of his guys might have been just about to pounce on you. You don't look back, not wanting to know the answer.

Vladimir extends his right hand to you with an open palm. You shake your head.

"I'm not returning the gun."

"Not the gun. Shake on our agreement."

You stare at the hand, then reluctantly switch the gun to your left hand while still trying to keep it somewhat pointed at the mafia boss, before you take his hand and shake it. Vladimir's hand is cold but his grip is strong and his skin is so calloused that you wouldn't have thought it was flesh.

"1 week," Vladimir says, still onto your hand.

"1 week," you repeat.

"And she must be pretty. As pretty as Daria. Or even prettier. No tricks." He drags out the last word into a sinister hiss, and you gulp and nod your head. If you were to repeat after him again, you're afraid he might detect the tremble in your voice. You wonder if he can feel your pulse through your hand just as he releases it and sits back down in his chair.

"Keep the gun. And help yourself to 1 of the girls if you want. The men will give you no trouble," Vladimir says, already returning his focus to the rest of the room. You look around and see that some action has progressed and some of his men and the women are fucking while others are still taking their time.

"Uh... no thanks, I'd better be going."

"I don't know who you are, but if you're not here in a week with my new wife to be, I'll find you," Vladimir says as a matter of factly.

You do your best to act nonchalant. "Cool, cool, cool. See you in a week."

You then get out of the nightclub as fast as you can without breaking into a run, clutching Vladimir's gun tightly until you're outside, before you find a dark alley and teleport away.
