SNW S2E02 introduce a new quirk of the canon: The time “push back”, such that there will be some events (let’s just call it Canon Event) that will always come about in Prime Timeline, albeit in different actual time. Aside from the aforementioned Eugenic War, I can think of a few other so-called “inconsistency”, such as how there are already Cloaking technology for both Romulans and Klingons before Kirk’s mission, despite TOS dialogue implies that Romulan first got cloak during Kirk’s mission, and then transfer technology to Klingon. (I think the current explaination is different cloaking technology, which have various quirks.)
So here’s the question: Under what situation would you consider “Time Pushback” being an acceptable explaination for discrepancy??
According to the DTI books, Worf never travelled universes on Parallels, he was caught in a probability bubble that was throwing up short-lived possible timelines that collapsed quickly.
In fact they postulate that Trek doesn’t have an infinite multiverse, but the one prime one that’s shifting as new probablity waves are spun off and reabsorbed as we saw in the episode in question and it takes a huge change like the Narada incursion or the human physiology change of the mirror universe to actually stabilise a waveform as a solid new timeline alongside prime.
