You didn't. Asriel, you didn't, it's me! It's my fault, don't you get it?! I can't...function. Something's wrong with me--everything is wrong with me!

[He gives up entirely on getting to his feet and just flops back onto the blankets before rolling onto his side. He couldn't bear to look at Asriel right now, he felt so guilty.]

What happened to being a star? What happened to smiling and laughing and encouraging others? All I can do anymore is hurt them. Hurt you, and Frisk. I project on everyone, just like Tabris says, because I can't truly understand anyone, just solve their problems based on my own, as if it even works! And now there's Bucky, and all he does is feel displaced because I'm not the Mettaton he knows.

[He brings a hand up to cover his own face.]

I'm not the Mettaton I know...and that's my fault. It is not yours.
