Gorgeous?
H-how gorgeous?
(Nah I don't expect you to link to a picture of her, you're more considerate than that)
I think if Serra were to become more important in the story, she would come to the realization that "my mirror may have become irreparably cracked and tarnished, but that doesn't mean I should stand idly by and allow others' to do the same. I will use every ounce of my ability to retrieve my son."
My logic is that Serra follows the mindset that "a mirror, like ice, can no longer be perfect once it cracks." However, she can do her best to prevent new cracks from surfacing, both in herself and others (such as Bennett).
Indeed, the mirror of Reborn may have its cracks, but she can do her part to ensure that new ones (e.g. Team Meteor) don't form.
