Jacen didn't react beyond the raising of one eyebrow. He remained exactly where he was, leaning casually against the wall next to Tenel Ka. He knew exactly what his Queen was thinking, that this blonde was getting one hit and one only. If she tried again, they would both use the Force to separate them.
He didn't speak up, merely nodding as Faith introduced him. He knew next to nothing about the previous encounters between the two Slayers and frankly he didn't care. Faith was in charge and he followed her orders. Regardless of her past. Well, he was hardly one to judge dubious histories was he.
He shifted his gaze to Jack and Spike, wondering how they were reacting to the situation.
