There was a part of me that was curious as to what Pixel originally had in mind for that line by Momorin: "What I need right now is a Booster. Now, who would have one of those..." I guess the original plan had one or more possible routes in which you reached Momorin without the booster, and had to go off and get it from Professor Booster. Wonder what his status would have been at that juncture...
Amused by this, I decided to incorporate that event in with my fourth ending mod and have that an actual spoken line as a part of that path. And of course, that stray event in the script sure ended up being a useful tool in making it look like the fourth ending was real when I posted my follow-up video telling people to open up Cave Editor and look at the script. Good times.
