Minor quibble (but then what other kind of quibble would it be):

In DS9: “The Adversary” the leader of the Breen Confederacy in the 24th Century is known as the “Autarch”.

Actually, “autarch” was the title of the Tzenkethi political leader, not that of the Breen. To my knowledge, the title of the head of state of the Breen Confederacy was never spoken (except perhaps in the form of Breen static).

Loved it.

Some amusing details:

• For Pike’s singing voice, he adopts a kind of Meatloaf/Russell-Crowe-in-Les-Miz style that is exactly the right mixture of masculine and adorable.
• The build up to the Klingon Boy Band: We know that Klingons love opera, heightened emotions, spontaneous group singing, and choreography (if you’re willing to consider martial arts a form of choreography). La’an even explicitly mentions singing old sea shanties which would seem to be an obvious way to translate the Klingons into musical form. So naturally, I was shocked that the Klingons would not immediately assimilate into their new musical reality. I even told my husband, “I can’t believe the Klingons would want this to stop!” And when it hit, everything made perfect sense.

David wasn’t aware that Kirk was his father

Technically, David did know that his father was an “overgrown boy scout” named Jim Kirk, but they had never met before and evidently knew little about one another aside from their mutual existence.

Just here to note two details I appreciated:

1. La’an still doesn’t know what a Romulan looks like after her adventure. The only one she met was surgically altered to look human, although Sera did drop a hint by complaining about the ears. Still, there’s plenty of aliens with non-human ears, so not really much to go on.
2. If she was paying attention, though, La’an did get another clue about Romulan physiology: When she shot Sera, the blood spray was green! Of course, Sera remembered her grandma’s old recipe for molecular solvent, so La’an may have thought that was the reason for the coloration.
