Foster is only seconds done with his outburst and he already hates it. Hates himself for it. For that... that. What kind of feeling was that? No.

Psi's reaction caught him off guard, but now that the temporary 'feeling' has evaporated, he's flooded with a different one, just as fleeting but no less unpleasant: absolute disgust. Not for Psi, no--but his eyes lid partway, going surface cold while his voice drops in contempt.

"Don't you think that's a bad idea?"

He doesn't understand him. Why would he even want to? Hasn't Foster made it clear enough that he's unpleasant by nature? That his very soul is nasty, untouchable and unattractive?

"If you're really trying to understand me and you don't hate me, then you're not doing a very good job."
