I'll have to rewatch this one sometime. I recall never really liking it that much when I was younger, but I've become better able to understand some of the deeper philosophical stories as I've grown older.
I feel exactly the same. Some episodes I didn't get the nuances or the message of, and this is probably one of them. I didn't remember the story much at all until reading MEG's summary.
I love Carolyn Seymour though, I know that much. She's fab.
