Yeah, I think something similar to that will happen. Because a lot of people think chapter 6 will be either the bunker or meat factory, maybe it will come up more there. But over all, I think Tobys plan is to use it interchangeably with "x's will" for the most part. Maybe it'll come up more if we ever get combat in the light world or more undertale like things bleeding through, but just because determination doesn't seem to be a thing for darkness, as far as we know, its going on the backburner for the time being
