So, the plot in season five of Disco is hunting down clues left behind by scientists who uncovered the technology left behind by a precursor race of alien beings who panspermiad their genetics all over the galaxy, resulting in all your favourite humanoids, like humans, Klingons, Romulans, and Cardassians, as seen in the TNG episode, “The Chase”.

And the antagonists of the season are not actually the tragically dumb young lovers, Moll and L’ak, but instead appear to be the Breen. We’ve learned Breen are, as Captain William Shaw might say, goo people. Or at least they’re semi-transparent so long as they’re within the confines of their refrigeration suit. If L’ak is any indication they can take a more solid, humanoid form, but the Breen appear to prefer to be Sour Patch Kids.

I’m going to speculate that we will learn that the Breen are not actually one of the species who resulted from the Progenitors seeding the galaxy, and as such the Progenitor technology is of limited use for them.
