[God. He's still talking?! Mettaton casts a slightly annoyed glance at Kaworu, assuming correctly that saying he had a question would naturally mean that, whether the bot wanted to hear it or not, he was going to.

And oh boy.

That was a question alright.]

Why?

[Mettaton's gloved fingers curl into fists, and he thinks back for a moment to his conversation with Zam. His apathy is bordering on those levels, where he might actually answer the question honestly and with no kind of defense for himself.

Kaworu can make his judgments upon hearing Mettaton out.]

It was my choice. And I regret it immensely. That's something you wouldn't know anything about though, right? Regret. Feelings. Empathy.

So think what you will.

[Although it would make Mettaton feel better to hurt Kaworu again, he instead reaches behind him, pulls his charge cord out from the wall, and gets to his feet.]

Call me human again though, and I am not responsible for what may come after. I don't care about what you think you know.

[So saying, he turns away from the white-haired young man and moves to leave. He can find a better place to charge.]
