Blaine probably managed to look innocent and guilty all at the same time. He hovered for all of three seconds before he pointed to the door. "I just really need to go lie down. You never know what might happen if I don't. Really, really sorry to jump ship, but you two will be okay, right? Puck, why don't you offer Quinn a drink? She's been running... see? From her clothes? Right... lie down."
