GTA IV - One Last Thing

After killing Darko Brevic in the last mission, Jimmy Pegorino contacts Niko and explains that he needs to talk to Niko. Pegorino asks Niko to meet him at the strip club in Tudor, Alderney.
Niko arrives and orders a drink at the bar. Pegorino walks up to him and explains that he is ordering Niko to do a heroin deal with Dimitri Rascalov, Niko is reluctant to work with Rascalov again due to Rascalov's earlier betrayal of Niko and involvement in Roman's kidnapping, but Pegorino orders Niko to meet Phil Bell at his apartment to do the deal.
Niko leaves the strip club, and phones Roman to explain the situation, Roman tells Niko he knows all about the deal and also knows where Rascalov is, Niko realizes that now he can now kill Rascalov and forget about the deal. Roman begs against this and thinks Niko should leave his life of violence behind and do the deal, with Roman planning to use the money to pay for his and Mallorie's honeymoon and buy a private jet to take himself and Niko to Vice City. Niko then phones Kate McReary, who advises Niko not to do the deal, as she doesn't think Niko should sacrifice his principles for money or take the chances with Rascalov.
