The news of Ulrik's arrest became news in Kattegat, and the lockdown lifted; everyone was surprised because Liv had always been passive in this type of matter, so this shocked both Lagertha and Herfjötur.
Naturally, they requested an audience with Liv, but she rejected it. Something was not sitting right with them, but they faulted Ulrik for his emotional approach to the situation.
Where was Karl? He was Ulrik's right-hand man yet could not advise him against such a foolish decision making them question his usefulness.
Since Liv rejected their offer, they turned their attention to Karl, meeting him in a tavern.
Karl was concerned but knew everything would clear once Ulrik explained himself.
Pushing for his release would only worsen the situation as they may be tried as co-conspirators, leaving no one on the outside to see what is happening.
