I see the Unnamed Black Chick is still aboard. At the very beginning of the show she enters the Bridge from the turbolift in the party that is with Riker. Dunno where she went after that, though.
How could Worf, to whom honour is all, overlook the shift change because of a crisis of confidence? This was an unlikely way to introduce us to the main theme of the show.
Worf has said over and over that there can be no greater honour for a Klingon than to die in battle. So why did he stop Gowron from killing Kahless when he'd just beaten him in, er, battle? And is it thought appropriate for lesser Klingons to lay hands on the person of someone of the stature of Gowron?
Surely someone with the personality of Kahless, upon learning that he was a clone, and an incomplete one at that, would have simply walked away from the situation to find himself anew?
In fact, let's think about the ersatz Kayless. Being a Klingon clone created by other Klingons, he's home-grown, ain't he? Sort of Kayless, DIY (little pun for the Brits, there).
All those different foreheads - are they all unique like fingerprints, I wonder? One might experience a measure of difficulty in taking the dabs, though . . .
And, yet again, where was the Universal Translator in this episode? Perhaps the one on the Enterprise has a sign hung over it; "Klingon spoken here".
