It was Picard's age in Insurrection that unsettled me. He's 70 years old yet able to fight Ru'afo like he's a young man. The Ba'ku homeworld will have affected him though of course.
This is nice consistency, really. Note how winded he becomes when fighting the equally geriatric Soran just one movie before (in similar "hot and high" conditions)...
The question is, original Leah or holo-Leah?
I'd love for it to be the holo-version, just for the scifi touch.
I find it entirely possible and likely that DeSeve just used the rank of Commander as a sort of automatic response. He was used to it while on Romulus, so naturally he automatically called any starship commander that.
The biggest nail in the coffin of the idea that Picard held the Starfleet rank of Commander back when DeSeve knew him is that we have no proof whatsoever that DeSeve
would have known him, or even of him!
This in contrast with "Encounter at Farpoint", where Riker calling Troi "Lieutenant" is a very natural mistake (or even a deliberate choice) to make.
We don't know if the Stargazer was the first starship he was assign too, or if it was another starship, or what class it was?
We do. In "Relics", Picard is specific that the
Stargazer was the first ship he served on.
What we don't know is whether he served on other ships besides that one and the E-D and E-E. We know he was
aboard a ship between the
Stargazer and the E-D, as per the "Legacy" story of him meeting Yar for the first time, but whether as a passenger or a skipper, we don't know (him being a member of the crew but not skipper might be unlikely, considering him already holding the four-pip rank and having one starship command under his belt).
What we also don't know is whether the
Stargazer was Picard's first command. Perhaps Lieutenant Picard served aboard her with such distinction that he was rewarded with the command of
USS Insignificant, after which he gained so much reputation and leverage that he became the next skipper of the
Stargazer by his own request?
...it still represent a starship, but which is not the Enterprise-A. Cause the Enterprise-A never had sideways nacelles, which the model does have.
By the same argument, the four-nacelled ship there is not the
Stargazer, because it is subtly different from the real deal, too: the wrong surface detail, the wrong registry number.
