The show I feel needs to end with Pike's accident and Spock's plan to take him to Talos and possibly even a further flashforward to a memorial service for him post Menagerie. Have Uhura sing the lyric version of the TOS theme like I'm sure she did in some comic at some point.
The thing is if they end it there, that’s the end of the story. There will be no Long Trek with this cast, unless they reverse what happens to Pike or allude that his condition can be reversed. And as you said, we don’t get to see Pike’s five-year mission.
The best Trek finales (TOS, TNG, DS9) leaves the crew’s future open ended. Instead of having them achieve a certain end point (VOY, ENT).
The only idea I really like is Uhura singing the lyrics of the TOS theme, since that theme does in exist in-universe.
They don't have to show the accident
That can be saved for a Long Trek.
I'm still betting the last scene of the last episode will be shot on the TOS set tour bridge, after a "refit"
Why does the Enterprise need to be refitted?
Why can’t it be the crew remembering their time on the Enterprise many years down the line, and select scenes from SNW are re-shot on the TOS bridge? And the SNW bridge is largely Pike’s perspective? Would fit in with an idea to not have the ship design tied to a construct.
It would leave the story open ended to be continued as adventures in Pike’s mind.
and will have the new Kirk send them off to do TOS
Pike handing the keys to the Enterprise to Kirk should be the penultimate episode, not the finale. This is not Kirk's show.
I've been thinking the last scene of SNW should be Spock wheeling Pike to the Talosians after the events of the Menagerie.
Why can't that be the cold open to the finale?
My idea for the final episode is that it tell the story of The Menagerie from the point of view of Pike's former crew, who are all a part of Spock's conspiracy to bring Pike to Talos IV.
Okay, sound good. But again, the best Trek finales leave things open ended so that they can continue having adventures.
