Happy 1969! It surprises me that Dark Shadows wasn't pre-empted on New Year's Day - all those parades and football games! I used to watch the parades on TV, and now I wonder why.
I feel sorry for Chris because he is blaming himself completely for Joe's descent into madness, when in fact Tom's grim fate was partially responsible...I think. But I haven't gotten it completely figured out. Back when Joe was himself, he could not remember why he had behaved so badly - i.e. he couldn't remember his victimization by Angelique. And I don't think he could remember what happened to Tom, either. Now that Joe's insane, he remembers what happened to Tom, and that's part of what's making him crazy. So Chris isn't entirely to blame...but how is that Joe remembers about Tom now? Is it that the shock of seeing Chris turning into a werewolf burst a door open in his mind? But apparently he still doesn't remember Angelique. Very confusing.
At any rate, I think this is the only episode in which one actor played both a werewolf and a vampire. I was impressed with how Don Briscoe made Tom seem quite different from Chris, to the point where I was thinking: "Can't Joe tell the difference? It's obvious that this is Tom!" But then, I always did like Tom better.
