I never got into Discovery, but that’s neat that they remembered that species exists. Someday I’ll give it another go. I like when Star Trek does go “…Wait that’s a thing we did, go back to that.” Partially why I enjoy Lower Decks.
I also saw some of the episode where the Universal Translator broke, and I wish that was a full episode, on how to deal with it. I’m kinda shocked the Federation never has that problem often enough where they need to have “Star Trek Esperanto” as needed for all cadets to graduate.
