When Garnier dismissed the horrified crowd and returned to his work, the Assassin stealthily made his way inside the hospital, and located the doctor. Altaïr then took the doctor's life with his [[Hidden Blade]]. With his final words, Garnier claimed that he was actually helping his patients; although Altaïr tried to rebuke all of his claims, Garnier persisted in his beliefs.<ref name="TSC" /><ref name="AC" />
Garnier claimed that the people he took were among the poorest and most ill of the surrounding cities, and that many had recovered and were grateful for his generous help. He said his methods were necessary to free people from the "''prisons of their own minds.''" Altaïr asked if he truly believed that he was helping them, and Garnier simply replied, "''It's not what I believe, it's what I know.''" Before he could say any more, however, Garnier died, and Altaïr was left to escape the area, and report his success to the local [[Assassin bureau]].<ref name="TSC" /><ref name="AC" />
在魔改的非权威的《刺客信条》移动端改编游戏中，加尼耶·德·纳布卢斯作为BOSS战人物，全副武装与阿泰尔·伊本-拉阿哈德决斗。Despite being canonically a Knights Hospitalier, he wears the signature white surcoat with a red cross of the Knights Templar. He fights solely by swinging on the ceiling with a grappling hook to use as leverage for an air assassination maneuver with his sword. Each time Altaïr succeeds in evading this attack, his sword gets embedded into the ground, giving the player a few seconds to attack him while he is preoccupied with pulling it back out. After losing more than half his health, he begins charging his attacks, such that each time he plunges it downwards, it unleashes a wave of destructive energy. Once his health reaches critical levels, Altaïr will wrestle with Garnier to slit his throat with a Hidden Blade. His death occurs in 1189 rather than 1191 as it is in the canonical console version.
