You forcefully crash through the ceiling in a room. You're finding that your superpowers include rapid healing, but not invulnerability to pain.

Waaaaait a minute... is this just your lab again? NOOOOOOOOOOOOO! YOU REALLY ARE TRAPPED HERE FOREVER!!!

...But the more you look around, you realize it's not actually your lab! It looks nearly identical to it but flipped, and things like the MULTI-USE BEAM STATION are the same... but there appear to be some different devices, and it's been been trashed in similar but different ways. Looks like someone else has had about as bad of a day as you have.
