Star Trek episode "Elaan of Troyius"

"Elaan of Troyius"

Season 3, Episode 13.

A top secret diplomatic mission, bringing two strange races together. The "queen" Elaan is a super-bitch is to be brought to the other planet into a political marriage. It becomes Kirk's job to "tame" her.

She actually stabs the Troyan abassador! There's a Klingon ship following them. Elaan's tears are said to be some kind of super love potion that ensnares men. And of course she ensnares Kirk. One of Elaan's guards, Kryton, ends up being a Klingon spy and sabotages the Enterprise. I was watching, thinking to myself how the hell does this guy have the run of engineering, able to get to and disable the warp drive and dilithium crystal. He snaps the neck of Watson, a redshirted engineer.

Kryton is soon phasered to death by a security guard--ahhhhh, why the hell weren't phasers set on stun there??

The Klingon ship attacks. I understand why there is no phaser power but are the photon torpedoes powered by the crystal? It would seem not when Kirk orders Chekhov to prepare the torpedoes before Scotty engages the new crystals.

Oh, yes of course, the necklace that Elaan is wearing is conveniently made of dilithium crystals. That's why the Klingons are involved anyway. At the end, there is actually a great space battle, with Kirk ordering some neat little manuevers--it is not just one blast. Now, at the end here, Kirk gives up Elaan to her new political marriage. And I am sitting here wondering why nobody seems to be too worried that Kryton was a Klingon agent in the first place!
