At the Kronenberg Castle, Viktor had a meeting with Danilov. Viktor raged over the Resistance's solidification after seeing the images of members involved: Meisner, Tavitian, and Claude Frenay. Viktor made the connection between the Resistance and Sean Renard's recent return to Vienna, and he blamed Danilov for Sean's escape. Just then, Sebastien knocked and entered with Adalind.
Danilov watched as Viktor asked Adalind if she recognized any of the men in the pictures, which she said she didn't other than to say the picture of Meisner looked familiar. She then admitted that she found a note signed by Sean on her dresser in her hotel room. Viktor wondered if Sean knew about Eric's child, but Danilov revealed that Sean had a relationship with both Adalind and her mother. Viktor, while mildly impressed, mused over the consequences of Adalind's carrying Sean's child instead. He ordered Danilov to find out who the father was "sooner, rather than later."
He was present when Prince Viktor found out that Sebastien was working for the Resistance and took him away.
Later, he and his Verrat agents interrogated Sebastien about the members of the Resistance and the whereabouts of Adalind.
His name came up in a conversation between Sean Renard and his associate, Jacques, when Sean suggested that Eric Renard was making a move and that the Verrat was behind what was happening. Jacques agreed, adding that someone named Danilov was in control.
