The silence falls over them, heavy and terrifying. All Reid can hear is Xavier's breathing and his own heartbeat. Reid finally exhales, but reluctantly. They're still so close, practically face to face, and he can't talk like this.

Reid turns away and bows his head, so his face is even more hidden, even in the dark. A few more inches and he could rest it on Xavier's shoulder, but he won't. At least this way, he doesn't have to look at the vague shadowed shapes of Xavier's face, or struggle to maintain eye contact. "Sorry," he says, nearly right into Xavier's ear. He only means to apologize for this kiss, but as soon as he says it, he knows there's a lot more he's sorry for.
