"Don't." It comes out with a growl, but it's not to Prudence. It's directed at Gongenzaka and Yuya, but also the Psionic and Taako. The message is a little different in the latter cases. Mostly Psi--he doesn't want his idea of help, doesn't want Psi to make some pointless gesture in the vain hope of inadequate mercy.

As for the first two... Psi has already beaten him to what he wants to say to Gon and Yuya, and the experience is actually a little disorienting--but with or without an outlet there, he's still angry. 'You don't know what you're talking about.' It's... disgusting. The suggestion that he hasn't tried hard enough to live, that his reasons aren't 'good enough' or his problems 'real enough' to or his reality 'bad enough'--

Then again, he could say the same thing to Taako, who gets a particularly hateful stare. As if magic were some brand new concept he'd failed to think about. As though this were a novel solution that, suggested by someone else, would suddenly bestow on him some miraculous renewal of hope. He's angrier still at Taako's attempt to interfere, like Pru isn't offering to deliver exactly what he was asking for.

Like Taako didn't know this was his other choice.

He doesn't blame the demon elf for abandoning him. But he won't forgive him for it, either.

Foster doesn't lift his head, but raises his eyes to stare up at Prudence, unmoving.

"You haven't even found the pendant yet," he points out coldly. "No pendant, no ritual." He 'smiles': bear jaw dropped open, lips pulled back like he's trying to grin.

"Go ahead. Put it through my eye, bury it in my heart, just don't... miss."
