You and Arson are assassin partners. You hate him and he hates you. You both hate each other but are forced to work on an important mission. You both kept fighting and didn't really focus on the job. All you both wanted is the extra credit to yourselves

The plan failed because you both were debating more than focusing. While he scolds you back during the fight with the guards..a guard stabbed him

"SHIT AH!-" he grunts and falls on the floor
