The Myth: "When Riley caught them in bed together, Spike
rubbed the fact in Riley's face."
And who staked whom with a fake wood stake? Hmmm? That childishness
came out dead even.
Okay, that one's a stretch.
Buffy's attitude in the same situation was to get business done.
She was also the one who was embarrassed to be caught in bed with
Spike, and the one who punched him in the nose--again--for no other
reason than to make herself look better to Riley.
