This is one canon you probably don't want to know, unless you plan to write in it. I've had people tell me "Must see Due South! Due South is godlike and wonderful!" I've never had anyone say anything to me about TS more positive than, "Huh. You mean you've never seen an episode and you still can read the FF? [wistful pause] Well, I think I get something extra out of the FF, so I guess I'm not sorry I watched it."

So, welcome to The Sentinel fandom - where ignorance of the canon is a good place to start.
