Clarisse is already shaking her head as Abby tries to explain herself. It's fine.

"No," she says, "I get it." She does. Really. And it worked out, because now they're friends and Clarisse can bug Abby whenever she feels like it. (Often.)

"It helps having someone else around. Back at camp I lived with my siblings, and at college I had a roommate too. We weren't... really friends or anything, but it was still good to know someone else was around, just in case."

In case of nightmares, or a random monster attack. Whatever.
