Kevin: "My name's Hedwig."
Casey: "How old are you?"
Kevin: "Nine."

"There's a flower on the pillows, a flower in the bathroom, like we're important."

Kevin: "Someone's coming for you."
Casey: "Who's coming?"

"The only way we're getting out of here is if one of them decides to let us out."
{refering to Kevin's split personalities]

"There's a man here, he abducted us and he's going to kill me!"
[speakaing into a walkie-talkie]

"We're meant for something, something horrible."

[locked inside a room]
Casey: "What are we doing here? What the hell is going on?"
[Kevin opens the door holding a rifle]
Kevin: "I was sent to get you for a reason."

[looking through the keyhole they see someone with high heels]
Casey: "Who is that? Maybe she can help us."
Claire: "We're here! Help us!"
Marcia: "We're in here!"
[the door is unlocked and Kevin enters dressed in woman's clothes]
Kevin: "Don't worry, he knows what you're here for. He's not allowed to touch you. He knows that. He listens to me."
