Well this part i don`t understand in game, to unlock assasination quest you must first help Triss rescue mages and she goes to Kovir to become advisor to Kovir king, so how is Radovid threat to her or Yennefer. I know Dijikstra can be convincing but why Geralt believe in such rubbish and decide let`s go kill king and dot even questioning that decision and what would happen to country without kingLOL nope he is crazy want to kill you sweety Triss damn go kill him with Phillipa she is good isnt she ?

Geralt of Rivia: Let's get out of here, Vernon.
Vernon Roche: Have you lost your mind?
Geralt of Rivia: You wanted to kill a king, not a cockroach.
