- "Xavier could have told me Christian was in danger, but he didn't, because he knew that would pull me away from our precious mission."
- ―Joseph about Christian's death, 2015.[src]
At some point before September 2015, during a mission for the Brotherhood the lovers were separated. At some point, Christian encountered difficulties, but the leader of the mission, Xavier Chen, kept it from Joseph in order to have Joseph fully focused on their objective, a choice that resulted in the death of Christian. All the other Assassins involved also died, save for Xavier and Joseph, the latter faking his death to plot his revenge on Xavier and the Brotherhood that in his mind robbed him of the love of his life.
