This episode seems to have been about Dr. Cox and his charming issues. One of the most interesting aspects of his character is that he has very little understanding of himself, frequently guessing out loud at his wishes and motivations. At some point, nearly every character has told him how he actually feels about something. I can't even begin to guess at the reasons behind his and Jordan's strange relationship, but I'd like to see further attempted explanations in the future.
p.s. Yet another occurence of self-conscious use of music. And I appreciated the reintroduction of the barbershop quartet.
