Ned doesn't pick up on the fact that Buffy is bluffing, continuing to look perplexed as he wonders why she, alone, it would seem, was unaffected by the experiment. Even Daneel had fallen asleep, and by all rights that was physically impossible for him. Perhaps she had merely not noticed. Perhaps whoever had trespassed on her dreams had managed to be discreet.

Crap, how better to describe it than that? "Sort of... participating in one anothers' dreams. Well, sometimes participating, sometimes just watching. Like a vision, except with information from two brains instead of just one." Wow he is really not doing a good job of making this any less complicated.
