please join me for Why Damar Is Definitely Alive and Not Dead
-Earlier it seems Garak would prefer Damar as leader of Cardassia (see the “Yeah, what kind of people Damar” scene).
-The person holding Damar when he dies, the person who establishes he’s dead, is Garak, who is known to lie. Particularly when it suits his purposes.
-Why the heck would Damar be wearing civilian clothing, rather than armor, when planning to charge a command post defended by many Jem’Hadar? Particularly if Garak wanted him to be alive.
-Damar’s death galvanizes the remaining Cardassian resistance, giving them the motivation that helps them overrun the Dominion. If he was only wounded, that would have slowed them down, or led them to leave a man behind with him.
-Damar, Garak and Kira have been hiding out at Enabran Tain’s house, the house of the head of the Obsidian Order
-Obsidian Order personnel are almost never shown wearing armor
-Garak is a tailor, and actually a very good one
Which leads me to my central idea here. The Obsidian Order may never wear armor, but like heck they are ever gonna walk into a situation without protection from stray phaser blasts. Contrary to opinions of certain beta canon authors, Cardassians are not stupid, and the Obsidian Order would likely invest in the tech to protect themselves - while retaining their civilian appearance.
Obsidian Order civilian suits have protection against phaser blasts worked into them. And of course, Tain had plenty of these - and probably had more stashed around his house. Garak could easily modify some of them to fit himself and Damar. He doesn’t tell Damar about any of this because he knows that Damar would have objections to wearing Tain’s old clothing, to wearing anything associated with the Obsidian Order, and to the idea of being better protected than Kira or his men.
Thus when Damar gets hit, although the Obsidian Order tech protects him for the most part, although several of the blasts wound him, and the overall affect is like being strongly shocked. Damar certainly thinks he’s dying, and falls unconscious from the electrical shock (Cardassians are a bit more sensitive to that anyway in my headcanons) and overwhelming pain (the Obsidian Order protective clothing is a bit like kevlar in that it protects you but you still feel the effects when you get shot - and Damar takes a bunch of hits).
Garak says he’s dead, and proceeds to lead to the resistance to victory, knowing that if he tells the truth - that Damar is just unconscious and injured, the rest of the resistance other than Kira will want to wait for him to recover - or at least leave someone behind to protect him - and they don’t have the time or manpower to allow that.
And like heck he’s going to tell Weyoun or the Founder that Damar is lying unconscious in the hallway - that would be potentially disastrous - better to say he’s dead.
Later, when Bashir shows up Garak knows Damar is going to (probably) be fine - he’s much more concerned about the death toll on the rest of Cardassia.
We don’t really hear about Damar again, but his absence from the peace conference could be explained by him still recuperating - or being busy dealing with the humanitarian and political situation in the Cardassian Union.
And that y’all is Why Damar is Definitely Alive and Not Dead.
