— Spoilers for Deus Ex: Mankind Divided follow!
When Adam Jensen arrives inside Golem City, Adéla informs him that Tibor and Dušan have been taken by the police to The Narrows. When Jensen gets there, Tibor is locked up behind bars and informs Jensen that there is nothing he can do to help as he will just put his family in danger. However, Tibor does give Jensen alternatives on getting into ARC territory.
Tibor later manages to get out of his cell and warns other ARC guards about Interpol closing in, believing ARC will keep his family safe. Tibor tells the ARC guards that Interpol may have arrived with the intention of arresting Talos Rucker.
After Rucker's death, Tibor becomes concerned about the way Rucker's successor, Viktor Marchenko, seems intent on destroying ARC's peaceful approach and making it more violent. He expresses his concerns to Roeg Gorman, a fellow ARC member, in a pocket secretary message warning him that something is not right about Marchenko's recent takeover of the organization, and that Marchenko might be planning a terrorist attack in what he refers to as "Stormsurge."  Tibor is right about his reservations, as Gorman's body is found at G.A.R.M. poisoned by the Orchid at the hands of the Shadow Operatives commanded by Marchenko.
After Marchenko carries out Stormsuge, which turns out to be an attack on Nathaniel Brown's Safe Harbour Convention, ARC is labeled as a terrorist organization. Tibor is arrested by Czech state police and appears on the news, talking about how Marchenko was not ARC and tried to destroy the organization instead.
- The player can confront Tibor after he warns his fellow ARC members about Interpol. Depending how one answers him, Tibor will either sit down and let Jensen go about his mission or warn the others. In what may be a bug or oversight, Tibor will later appear on the news even if he is killed in ARC territory.
