This week on Yesterday’s Star Trek, Mike and Tyler kick off Season 3 of Deep Space Nine with Episodes 1–3, and the show wastes absolutely no time shifting gears. In “The Search, Parts 1 & 2,” the Federation rolls out the Defiant, Sisko goes founder-hunting in the Gamma Quadrant, and DS9 dives headfirst into paranoia, power plays, and the uncomfortable reality that peace might already be lost. Then, just when things couldn’t get heavier, “The House of Quark” swerves hard into Klingon politics, honor culture, and one deeply inconvenient marriage.
