Mine is that Picard talks in his sleep.

To be fair, we don’t _actually _ know if this is teasing a crossover with the Nickelodeon property… but the expenses used to give us a new Captains Chair and the Patrick Starship give me pause.

My money is that if this appears in an episode, it would be in a limited fashion. Think the Moriarty teaser in Picard S3, or perhaps the Quin vs Q shenanigans might be more apt in that episode of Voyager. (It happens, but is largely restricted to a brief segment of the episode)
