When the Stephenson arrives, Veltr'a transfers M'Kress to the brig. When
the Sarek arrives, Veltr'a stuns M'Kress in order to transfer her to the
Sarek in a stasis pod. She turns out to be feigning unconscioussness,
so he stuns her again. But the Vulcan priests on the Sarek find they cannot
allieviate her Plak Tow.
House Mauro informs the Klingon trio of more about M'Kress. They bet
blood wine on which of them will be the first to mate with her.
The modified ceremony of Koon-ut-kal-if-fee is held at the Temple in the Vulcan Quarter on New Lhasa. Captain Horah-Marush and Commander Quayn are there, on the former's insistsence. When MíKress discovers Petersen's choice of champions, she demands her batíleth before berating both Petersen and the Klingons.
M'Kress fells one Klingon. Petersen asks her to stop, and she asks if she accedes, but he doesn't. The prone Klingon dematerialises - beamed out by an orbital shuttle. M'Kress kills the second before, unmated, her Plak Tow subsides. The final Klingon refuses to stop fighting after his fellows have been beaten, and attacks anyway. She receives more injuries - to limb and torso - and collapses. Before he administers a coup de grace, he is stunned - by Horah-Morash.
Horah-Morash has angered Vox and his colleagues, but by smuggling in
a phaser and teleporting out the injured, he has limited the fatalities
to one Klingon. Starfleet can at least heal the physical damage.
Koon-ut-kal-if-fee translates as "marriage or challenge". I don't know how to translate "just challenge" into Vulcan.
