Mandela Effect:
Originally: No one noticed Picard having some crystal
New timeline: Picard had a crystal in over 70 episodes
Jean-Luc Picard, captain of the Starship Enterprise, The Next Generation, had a crystal on his desk that he played in over 70 episodes, but we never noticed it?
Well, a replica of the crystal is now for sale in the Roddenberry shop, advertised as having appeared in “no fewer than 78 episodes”. Well okay then. Wow.
