In Re:Zero's Arc 6, Subaru is repeatedly pushed down massive staircases in the Pleiades Watchtower after losing his memories, leading to brutal deaths and driving him to madness as he tries to escape the loop, culminating in a dark "insane" run where he tries to kill everyone to prevent being murdered. The incident, often featured in memes, stems from a corrupted trial where he's stripped of his past, making him vulnerable and leading to tragic, violent repetitions.
The Staircase Incident Explained:
Memory Loss: In the Pleiades Watchtower (Arc 6), Subaru experiences a trial where he loses his memories from previous arcs, effectively becoming his naive, pre-isekai self.
The Push: Someone (later revealed to be Meili in a corrupted state) pushes him down the stairs, causing him to die brutally.
The Loop: Due to his "Return by Death" ability, he goes back to the beginning of the day, only to be pushed again and again, experiencing the same horrific fall repeatedly.
Descent into Madness: The repeated trauma and confusion, combined with the tower's miasma, break Subaru mentally. He becomes paranoid and decides to arm himself and climb back up the stairs to kill his companions to stop the cycle, leading to a very dark path.
