In Star Trek: Strange New Worlds, episode “Subspace Rhapsody,” towards the end of the final number, Spock notices that the meter showing frequency of the subspace field is just short of what is needed to break the improbability and return the universe to normal. So he joins in the final dance number to help the crew reach the needed frequency. It was a nice touch to show Spock’s reluctance to go along with the musical reality as well as his willingness to complete the mission.
