The character referred to as Hugo's Grandfather's Victim is not a conventional individual with a personal name or detailed biography but is instead a collective entity or vision that appears in the narrative. These are the spectral victims of a past tragedy caused by the madness of Hugo's grandfather. When the group ventures into the abandoned warehouse to find the cursed painting, the artifact's supernatural power materializes the hidden regrets and guilt associated with those who come near it. In the case of Hugo, a firefighter working for the Louvre's security services, the painting brings forth the apparitions of those who suffered due to his own grandfather's actions. Confronted with this manifestation of his family's dark history and overcome with paranoia and regret, Hugo loses all trust in his surroundings and his leader. His inability to cope with the guilt inherited from his grandfather drives him to his final act: using his lighter to set himself on fire, sealing his own fate. As such, the victims of his grandfather are not active characters but serve as a catalyst for Hugo's psychological collapse and death, representing the curse of the painting made manifest through ancestral memory.
