Naomi and Sam
Duncan, the principal at Sunnydale High and old friend of Naomi and Sam's, is an attorney trying a malpractice case and Sam is his expert witness.
Sam ends up getting slammed by the prosecution, who tears him apart. Naomi comes to his rescue, catching his free-falling ego, and he dives back into the case.
He then figures out what actually happened. The doctor on trial, Dr. Allen, did indeed make a mistake that killed the patient. Allen asks Sam to cover for him.
The next day on the stand, Sam almost does that, but the clever prosecution realizes his careful words mean that Allen did indeed miss something.
Sam ends up telling the truth, losing the case, but saving his reputation and conscience. Meanwhile, Naomi goes out on a date with Duncan.

Later, when Pete tells Violet he's asking Lisa out, she's supportive.
He's really, really angry, and regressing, but he's at least getting some action. Sam gives him a lecture but he's not having it.
