Background
In Russia, Lysowsky spent years in 23 remote prisons, gaining tattoos and joining the Russian Mob, eventually becoming the Pakhan. At some point in his life, he met Katya, had a son, Lyov, and then forsook his family, breaking out Lyov's kidnapping victims.

Honor Among Thieves
In Season Two, Arzeny first appears to offer help to Natalya Chernus, breaking her father out from Lyov's hands. But, since she is actually allied with Lyov, she refuses, making Arzney look like the villain. He later pays the ransom despite what Natalya says.
