I have preferred responses when it comes to indulgent transformation nonsense:
Any interpretation of the list that includes the potential for actual drama is a mistaken interpretation. I might want that for a serious story or something intended to be dramatic, but as this list is in regard to what I call "indulgent transformation nonsense", no. This is, at worst, a comedically huffy place.
I bring this up because it was while evaluating these preferences of mine that I decided "to heck with it, I should just double down on Sarah liking this sort of transformation. It's fun, it's in character, she should just be thrilled about it."
As a result, I went from being sort of feeling "meh" about this part of this storyline to liking it again.
And I really was feeling "meh", because I sort of agreed with Sarah in panel two, and I felt like there wasn't much more to what was happening than an excuse for indulgent transformation. I'm not opposed to indulgent transformation nonsense, but I want more than that when it's part of a story. I feel very self conscious if I feel there isn't.
Sarah's ecstatic reaction, and the potential reactions to whatever happens next, however, has gotten me on board again with this nonsense.
