Die Hard with a Burnham
"There Is a Tide" tries to do what should’ve been done many episodes ago: some world-building within this century. It may be too little, too late, but I guess I’d rather see it attempted rather than not seeing it at all.
After having exploited Tilly’s tactical weaknesses and seizing Discovery, Osyraa takes the ship back to Starfleet Headquarters, where she uses the subterfuge to get inside the base’s shield perimeter where she demands … an audience for peaceful negotiation. I admit I did not see that coming. Turns out there’s more to Osyraa than previous episodes — in which she, say, fed her nephew to giant worms — had indicated. She wants to form an alliance between the Federation and the Emerald Chain, providing a new economic model for the Federation through its mercantiles in exchange for access to Discovery‘s spore drive, which she believes the Emerald Chain has the scientific resources to reverse-engineer and mass produce. This could be a benefit for the entire galaxy, possibly solving a lot of problems posed by everyone’s dilithium shortage.
