Some exclusions may apply.
I can't imagine this storyline anymore without Grace showing off the male variant forms. There would always be some sort of visual to show what they had in mind, but I find having Grace actually morph far more preferable to that, and it makes it less awkward to be moving towards the end of this with the forms in a "to be programmed" state.
That said, this storyline won't be the last we hear of these forms!
I mean, obviously. I went through the trouble of establishing all these things, so, yeah, but that declaration felt like the sort of thing you put in a comic commentary.
