I only saw Phantom once (in ‘99). I never bothered with the other prequels. I’m unfamiliar with the story or the actor Morrison. I didn’t know who that was at the end of the episode.
I respect your avoidance of the prequels - if you didn’t like The Phantom Menace, chances are the other two would disappoint you just as much as expected. But I recommend reading into the general story, because in my opinion the broad strokes of it are fantastic. Even though I think he missed the mark with writing and directing the prequels, I have huge respect for George Lucas as an ideas man.
I honestly really admire how new canon content like Rogue One and The Mandalorian is trying to bridge the massive divide between the originals and the prequel era. Both are totally “old-school Star Wars”, aesthetically and otherwise, but there are things that connect to other parts of the timeline and small things for prequel fans too.
