Part of me likes that we're getting some Breen lore, part of me is worried that spending more time inside Breen culture takes away some of the inscrutability and unpredictability that made them so menacing in DS9, and part of me is a little disappointed they didn't go with the Typhon Pact "there are actually five different species all pretending to be the same Breen" interpretation, because that always made me giggle. But all of me fukken loves one thing:

Michael's short little throwaway "wait, you're Breen?" to L'ak pretty heavily implies that this is the first Breen anyone has seen without an encounter suit in over a thousand years. Way to go, Breen!
