Or then their very intention was to create ominous confusion... A valid cliffhanger technique, one that often angers the viewers of Part II (to see where it leads, read Stephen King's Misery).
Or it could just be bad writing/editing/direction. The simpler explanation is usually the correct one. I love Discovery like the next person here, but the last episode was quite sloppy in some places. Sorry...just doesn't track here.
For example, after realizing that much of NuBSG's "plan" was literally nothing more than the writers throwing random shit against a wall that sounded "kewl" for that episode (and conveniently forgetting about it in all episodes thereafter), and with Moore and Eick admitting as much, I'm wary of assigning grand conspiratorial designs to these stories and giving them more credit where credit is due. One thing that always comes to mind was one scene with Roslyn reading the Book of Pythia to Adama and finding a reference to "He who should not be named". Who the hell was it? The Cylon Imperious Leader? Count Iblis? Fucking Valdemort?!? Many of us fans spent whole seasons debating who it could be and never got a payout. Nothing in the Blu-Ray commentary, either - in fact, IIRC, that line of dialog was talked-over by the narrators and never commented on. Feh! Too much wasted effort trying to dig down into deeper meanings that were never there. Not even intentional red herrings to invoke misdirection and thought-provoking analisys. Just...nothing.
They've done a pretty good job in general in DISCO, IMO, but I think the things that people were confused about in "Vaulting Ambition" was due to the fore-mentioned lack of focus on a cohesive narrative. The magical ISS Charon Palace location is another good example. Is it nearby and can fire while cloaked or several parsecs away and has near-unlimited-range weapons capability? If they
were close enough to lay waste to a planet, then why did Burnam and Lorca need to take a shuttle to it at warp for an extended period of time? Why not just beam over? If they
could fire on a planetary target at such an immense distance, why did Georgiou complain about "warping all the way across the empire" (paraphrasing there) to get to the rebel planet and finish the job that Michael couldn't? Too many incongruities in too many places for it to be some intentional cliffhanger tactic to keep viewers on the hook.
Nope. Just bad production (in this case).
