the building blocks they are now playing with could make for one hell of a FRANCHISE finale.
- In the Star Trek subreddit, they are positing that somehow Jack (or his blood) will be the key to reviving Picard's body as Locutus, who will be controlled by the Changelings as a hive mind that commands the entire networked Federation fleet.
- Janeway could easily appear. We could feasibly see DS9 cast members appear (besides Worf). Hell, if you read the blurb about Kirk's body, it mentions that his body was retrieved for Project Phoenix..... meaning that since William Shatner is still alive.... KIRK COULD APPEAR!
- If the bad guys from the final battle are a fleet of Federation ships controlled by a hive mind, who are the good guys? The museum ships! Enterprise A, Defiant, Voyager for sure, and very likely NX-01, Excelsior, Enterprise E and the mystery in hangar bay 12.. a fully-restored Enterprise D (with a new stardrive section salvaged from a different decommissioned Galaxy class ship)!
Essentially you could in theory have an iconic big bad as the face of the enemy, fighting a team of pretty much every iconic hero ship in franchise history (aside from the Discovery which is in the future, and the TOS Enterprise and original Defiant which were completely destroyed), with core cast members appearing from most of the series.
If Star Trek were to end (which it won't), this is setting up a hell of a way to do it. Do I think any of this will happen? I'd say we could easily see most of it. I don't expect to see any more DS9 cast members or Kirk. I don't even think we will see the Enterprise E. I do think we are going to see Locutus and the Enterprise D though, and that our hero ships are going to fight the networked fleet. I think Shaw's line about hot dropping the D's saucer section on a planet was to remind us that it crashed so that when it returns, we are even more surprised.
