Breh I like Victarion but come on. His brother, who raped his wife and very likely killed Balon, asks him to capture the most beautiful woman in the world AND three dragons and bring it back to him....and this retard believed every single word of it.
How is that not dumb. He doesn't realize he's being set up? That horn is either some bullshyt or Euron is not far away and is just waiting for the chance to kill Victarion and take all the glory. Remember that red priest told Tyrion that a one eyed kraken was following them.....
