NEARLY A MONTH LATER:
"Hey Dimitri, I don't think I'll be doing this deal with you. We have other business to finish.. And now.. You're about to learn a lesson, actions have consequences. You screwed me over, now you're paying for it. Shame that'll be the second last thing that goes into your head." Niko said, pointing his Colt pistol at Dimitri after having cleared the area of everyone but Dimitri himself.
"YOU'RE the one who's going to learn a lesson. People aren't going to be happy if you kill me. [translated] Stupid motherfucker!" Dimitri cried, trying to hide his fear.
"I never been very popular, don't plan on changing that!" Niko cried.
"Niko, it's not too late, we can work this out! It was a long time ago that I pissed you off. Forget about it. I didn't mean nothing. Please. Think about Pegorino, he's got nothing without this deal. It was never my idea to set you up. Go easy on me. We were friends, remember? You don't need to do this. You're fucking a lot of people over by killing me. Hey, come on, we got history. Don't fuckin do it!" Dimitri begged.
"I'm sorry Dimitri.. But this world is better off without you!" Niko cried.
"Bu-
Niko shoots him in both kneecaps, then in the head as he was trying to get up.
"I should have put you out of your misery a long time ago. Goodbye, Dimitri."
Niko calls Roman:
"I killed Dimitri, it's over. He was on the Platypus, the boat I arrived in Liberty City on. So it seems it ends where it began." Niko said.
Roman: I guess you did what you felt you had to do. No deal, no money, no hot tubs and models. But Dimitri will not bother you again. I will see you at the wedding, yes? Remember to wear a suit.
"I'll be there Roman, don't worry." Niko said.
Niko calls Kate:
"Hey, Kate. I took your advice. I cut my connections with that man." Niko said, not having the heart to tell her what really happened.
Kate: I'm really proud of you, Niko. It must have been really hard to turn down the money and stick to your principles.
"Well it was the right thing to do. Are you coming to Roman's wedding?" Niko asked.
Kate: ... Can I bring Dash?
"I.. Okay, sure." Niko replied.
