Zuzana tries to figure out Karou and Akiva's relationship, all while Karou is translating from English or Praguelish (aka Czech) into chimaera-ese or whatever Akiva knows how to speak. Don't worry, Zuzana, we don't get it either.
After getting exactly nowhere, Zuzana tells Karou that the police are at her apartment.
They think her little flight was a "disturbance" (33.54) and they want to question her.
Well, Karou's not too stressed about that; she's planning on going away anyway.
As she leaves, Akiva makes her promise not to go with Razgut through the portal. Karou says "okay" (33.83).
