Jack was at a Moscow nightclub and killed a man named Anton, who was revealed to be an associate of corrupt high-ranking Russian official Viktor Chagarin.

At the Russian prison, Jack makes a deal for a lighter sentence in exchange for his testimony on Komarov so he can get close to Komarov and save his life.
