The Fight IS the final track of Act III.
I finally listened to Act III. I've been intimidated out of listening because, how do you live up to 15 years of anticipation? But today I listened to Act I and Act II, so I figured, why not finish the marathon?
Spoilers, though idk if there's anyone here who hasn't heard it yet.
So I remember that the album was released two tracks at a time via Bandcamp. The last song was theorized to be The Fight, because of the song title being teased as starting and ending with T,, only for it to be revealed as "The Fate of Thomas Light.", which ends with the abrupt execution of Light and the end of the album.
It shocked me that it would go like his. How are you going to end the story on the implication that your protagonists have lost after all this time? Does the story really end like this?
Then I realized, That's the point. Are you just going to walk away and accept that the album (or the war) just ends like that, or are you going to do something to change fate?
A few things didn't add up. The tracks were released 2 a time, yet it ends on an odd number. The Fight was said to be an Act III single, but it never made it onto the final track listing.
The intent, I believe, is that you're SUPPOSED to figure out that you must play The Fight after The Fate. You must take action in order to create the "true" ending, just as humanity must save itself and not rely on a hero. Refusing to take the end of the album as prescribed.
The Fate ends very abruptly with a cutoff, unlike Act I and II's fadeout endings. But The Fight ends with a fadeout. I believe that that's a clue that The Fight belongs at the end. I don't think it's a coincidence that "The Fate of Thomas Light" and "The Fight" both fit the T-t name teaser, either.
Is this cope? Yeah probably. But I think it makes a more satisfying ending, both narratively and musically.
tl;dr I believe that the end of Act III is deliberately unsatisfying as a clue to put The Fight at the end yourself, just as humanity must take action to save itself.
