Silco's lips go thin, and there's a twitch of his mouth, as he pointedly said: "I'm sure it must be wonderful for you, to have such a sunny disposition on life."

It was a mantra he'd repeated toward Jinx time and time again, everyone leaves. They only had each other, and before? He'd had nobody, other than Singed's weird experiments, and he hardly trusted the Academy Dropout further than he could throw him.

Prickly, obviously didn't even begin to cover it.
