Recap / Star Trek Deep Space Nine S 04 E 26 Broken Link
Odo is falling apart. A sickness no one on the station can identify or fix. Which means there's only one solution: Head for the new Changeling homeworld and get them to fix him. But the Changelings have other ideas in store for him...
Body Horror: The way the female Changeling views Odo's fate. "Perhaps it would have been more merciful to kill you."
Not to mention Odo falling apart throughout the episode.
Brick Joke: In the previous episode, Garak mentions that he wasn't always a tailor; he used to be a gardener. And while regaling Odo with tales of his time as a gardener at the Cardassian Embassy on Romulus, it's clear that his stay coincided with a number of mysterious deaths of Romulan officials.
Easily Forgiven: Averted; Garak gets six months in a holding cell for assaulting Worf and trying to start a war with the Founders. Odo thinks he got off easy.
Naked People Are Funny: An odd (and facetious) variation that starts when O'Brien comments on how flying the Defiant into the Gamma Quadrant without using the Invisibility Cloak makes him feel naked. When Worf and Sisko concur, Dax chuckles at "being in the same room with so many naked men."
Pretext for War: Gowron is seeking to turn a border dispute into war with the Federation.
Odo: When I joined with the other changelings in the Great Link, I felt something I've never felt before. In that moment, I knew I was home. For the first time, I felt that I understood my people. Their distrust of the solids, their willingness to do anything to protect themselves. And then in an instant it was all snatched away. I'm trapped in this body. I can never rejoin the Great Link.
Garak: Don't tell me you'd object to a little genocide in the name of self defense?
Wham Episode: First the female Founder tells Garak that Cardassia was dead from the moment the Obsidian Order decided to attack the Dominion. Then Odo is punished by the other Changelings by taking aways his shapeshifting and making him permanently human. And if that wasn't dramatic enough, we then find out Gowron is about to wage war with the Federation, and the episode ends with the revelation that Gowron is a Changeling in disguise.
Wham Line: "Gowron, leader of the Klingon Empire, is a Changeling."
