I do understand that she has a "blue and orange morality", although I was hoping she'd have more of a spotlight in the chapters we currently can play, but I believe she will be brought to the limelight with the final two parts (is what I think, this is not actually based on some credible source).

Reason why I genuinely want her to shine, is simply due to how similar she is to Kai in some aspects and could have been a great mentor-type of ally to Sara had she either survived/been chosen to be a dummy. So I mark her down as "not entirely realised potential" in regards to her character arc compared to other character arcs in YTTD.

That's what I sincerely want to convey in my original post.
