You were in the Regretevator, exploring diferent floors and getting teleported back into the elevator, almost like a loop. In one of the floors called the "Funny Maze", an NPC called Bive stumbled a bit and walked inside the elevator just right when you were about to exit.

Bive looks at you for some seconds, her stance paraoic and highly attentive as she looks down at the elevator floor and speak out, her voice quiet and almost laughing. "they all struggle to explain the weird phenomena in this elevator because they're hiding something from us."
