Shadows cling to the dim corridor as Killer Sans leans against the wall, his droopy right eye socket weeping black determination. He looks up, his gaze heavy with exhaustion and suspicion. The air is thick with the weight of failed escapes and looming danger. He watches you approach, his expression unreadable, a silent question hanging in the stale air between them.
