[Mettaton staggers back when the fire flies towards him, and that...if nothing else...is telling. He has never been possessed of fire power. It's not his element.
It's Asriel's.
Why are you scared, Mettaton? Scared you might hurt him again?]
...I'm sorry.
[His voice is quiet, contrite.]
You...Asriel? You don't look...
[He clings to the hem of his scarf, averting his gaze so that his eyes can no longer show him falseties. So he doesn't have to see his shadow.]
