There's quick as lightning shock passing over Peter's face, courtesy of the water's effects on his powers. But his expression evens out. If Chara is trying to get a rise out of Peter, they'd have to try someone more than that.

It's not like Peter wasn't already aware of what the kid was capable of.

In the months Peter had known Chara, the other Chara, he'd heard of the child trying to kill Papyrus in cold blood. He'd sat the trial that had come of the whole affair. He'd mourned when Chara had slain Sans. It didn't come as such a surprise that Chara had killed before. It wouldn't come as a surprise if they did again.

"She's alive here. You'd get into a lot of trouble if you tried anything again." Peter shrugs, feigning disinterest. Peter knows what Chara is, but it still makes him a little- sick? disappointed?- that such a kind woman had to be a part of it. "It's not like how it was when you were here before. There's not trials and three days in jail. They could make you leave. They could force you into a cell indefinitely."

He sighs, continuing like he still believes he's talking to the same child he once knew. "And that's just the captains. People like her, you know. They might not forgive you hurting her like they did with what happened with Sans."
