During that time he proudly claimed to have literally squeezed the life out of his own father. One day King Richard became smitten with Madalena but his attempts at wooing her failed. Gareth was then ordered to kidnap her and bring her to the castle. He was present at the forced wedding between the King and Madalena and witnessed Galavant interrupting the ceremony. He was about to engage him in battle when Galavant dropped his weapon. Instead of fighting Galavant professed his love for Madalena and in a shocking turn of events to she spurned him. Madalena willingly chose to wed the King prompting Gareth to bring Galavant to his knees with a punch to his stomach.

Gareth, upset, says that it's not his fault that he has to kill Richard the next day because Richard never stood up for himself.
The next morning, Gareth returns and tells Richard that they've come to rescue him. However, he refuses to take anyone out except Galavant. Galavant knocks him down and tells Isabella that he remembers saying that he loved her and doesn't regret it. As they kiss, Gareth knocks Galavant out from behind and drags him away.

If Galavant comes back then Gareth will have his friends killed. Richard figures that Gareth loves him and refuses to abandon his friend, but Gareth insults him until Richard has enough and goes.

At the castle, Richard and Madalena summon Gareth when they learn that Galavant has disappeared. Gareth claims that he overslept, and Madalena tells him to kill the others. Gareth agrees and goes to the dungeon, and leads everyone out. He then tells the prisoners to knock him out, take his keys, and escape. They can't knock him out so he finally just gives them the keys and turns them all loose... except for Sid, who he holds on to as insurance in case Galavant breaks his word.
Back at the throne room, Gareth admits that he didn't kill anyone. Kingsley, furious, declares that the kingdom has gone soft and draw's the king's sword from his scabbard. As he advances on Gareth, Madalena stabs Kingsley in the back, killing him. She tells Gareth that Kingsley wasn't her type and gestures to him to take Richard's throne.
