They do that thing where a character is overwhelmed and the doctor orders them to relax

Riker shows up!

Riker runs into O’Brien and says he has nothing to say to him

Kira gives Riker a tour and once she gets through the security on the Defiant, he shoots her and beams aboard some of his friends

In what has to be one of DS9’s goofiest moments, Riker takes off parts of his beard to reveal himself as Thomas Riker. If he had shown up with slightly different facial hair, would anyone care? But if someone noticed that parts of his beard were fake, how would he explain that?

Dukat shows up and the episode automatically starts getting even better. Odo and Sisko think that Thomas Riker is working with the Maquis and Dukat explains how this could start a war with the federation

Sisko gives the Cardassians some pointers on how to destroy the Defiant

Riker and Kira fight over who is a better terrorist

Dukat doesn’t understand why Riker wants to attack a certain area of space. Their Obsidian Order observer confirms that the Obsidian Order is up to something in that region

Sisko works out a deal with Riker to turn himself in

I don’t quite understand the kiss at the end. I thought they hated each other.
