I just don't remember specifics, just a blooper in 1970 and the last minute of the last episode. I know that when I watched again in 2002, it had impact. They were willing to go on all sorts of unexpected twists and turns in stories... 1897 spoiler:[spoiler]case in point, zombie Quentin, then revived Quentin...[/spoiler] So, while I knew Barnabas came back somehow, anything really could happen in the meantime. I even managed to suspend disbelief a little, and wonder if he really was a ghost.
