Summary
The dichotomy between black and white is your constant when it's time for you to meet the whole new civilization Frisk brought along with them to the Surface.
As a parent, it's not easy to trust others when they've hurt your child.
So when that new civilization decides they owe Frisk both for saving their kind and for still hurting them during that process, you've got plenty to say to them.
Forgive as easily as you once did with others during a stage of naivety? Oh, hell no.
They better have a good reason for hurting your child and an even better one for wanting to be a part of their family.

My True Reflection by Jack_of_Knaves

Summary
When Chara Dreemurr lay dying in the Hall of Judgement, all she could think about was seeing Rei again, wrapping her arms around her fluffy brother, and telling him just how sorry she was that she couldn't protect him, that she couldn't protect them all, from her twisted reflection.
What she didn't expect after her eyes shut was for them to open again in an unfamiliar room inside something called a hospital with her wounds cleaned and tended to before being taken into the care of a doppelganger of her mother and what seemed to be a second reflection, named Kris.
What she expected even less was to find herself part of a prophecy that foretold the world's destruction and how it would be saved by Four Heroes: two humans, one a noble warrior, strange and mischievous yet just and brave, the other, a devilish rogue from parts known yet unknown, a monster, brash and bold, and a lonely prince from the dark.
But, what Chara didn't expect least of all, was her and Kris growing closer over the course of their adventures... and coming to see each other not as reflections in some unseen mirror, but as something more, something deeper, something intimate.
Their true reflection.
