"I don't know..." On the ferry, Clarisse leans back against the railing, her arms crossed over her chest. "If you don't know what one is already, maybe you're not supposed to."

She's just messing with her. Mostly, anyway. There's a small part of Clarisse wondering if she's not right in thinking that if Vega doesn't know what a rifter is, maybe she shouldn't be telling her.

A very small part, though. Like 10% or something. And it's obvious from the look on her face, the smug little smile tugging at the corner of her mouth, that the other 90% is just Clarisse being a dick.
