[The Batter's mouth opens and shuts with a loud snap.

It's actually an involuntary action on his part and genuinely not meant to scare Ren. The thing about this form was that it was brought about by those who saw the Batter in a negative light and the Batter himself was affected by his own views as well.

And he hated what he saw in the mirror. An emotional thing that couldn't control itself and himself staring back, over and over again.

So this appearance was more expressive then the human. Somehow. Or maybe the Batter genuinely did not know how to proceed.]

....if someone you know or care about is suffering it's better to end things, even if it means ending their life. Physically, emotionally. Metaphorically.

[He can't explain it any more then that. It's a personal view of the Batter's. He would not let someone he loved suffer. Although what he means by 'metaphorically' may go over Ren's head and he intends on it.]

Can you?

[It's not a request. The Batter's face isn't the only thing that's changed. His arms have lengthened and his hands have been shaped into large claws. They look weak, long but so thin that Ren doesn't have to look hard to see bone. But they sharpen to points that were effective in tearing apart flesh and bone.

He reaches out to Ren with one claw. The Batter has zero intent on hurting the girl and if she waits him out, she'll find that the purifier won't even touch her.

The Batter was trying to make a point. Ren saw this form, she knew what he had done. So was was the point in staying? There's nothing here!]
