No. I was pretty close though when I picked up the series during Season 2 and Starco gave me such a raging heartboner that I got Katawa Dick for a week.>>99712257
A lot of it didn't really have anything to do with what we're expecting from the finale, it just felt like one.
I remember the first part was Moon and Star running through some corridor under the castle, they had to do something with Star's wand, but then they realized Star didn't bring her other four wands (???) and thought they would have to go back (?), but then Moon realized the other wands correspond to Star's other outfits (??) and somehow that resolved something. I don't know what was getting cross-referenced with the four wands thing. My brain rationalized this as a flashback scene while this was going on, I guess vaguely corresponding to some alternate Battle for Mewni.
Around this time my point-of-view also transitioned from full immersion to actually watching the show, standing alone in a dark hallway, looking up between several TVs anchored near the ceiling.
The most vivid memory from this part was seeing a list of seven episodes next to one of the screens, written in black ink on some kind of parchment scroll. I assume they were supposed to be episode titles because I distinctly remember "Divide" and "Conquer" being the first two points, but I don't remember the other five. "Divide" had a red stamp or seal next to it, I assume because I had just watched it.
The last part was more vague. Star and Marco were in some dark room or space, maybe their bedroom. They both looked significantly older but weren't quite adults. They were being confronted by a small crowd of people from one side, obscured in the darkness. Rasticore, of all people, steps forward and points a wicked looking gun at them, and Marco draws his own while they stare each other down. I don't remember if any words were said, but I got the distinct impression that they were being accused of killing Queen Moon.
