I only saw the pre-Barnabas a few years ago and was amazed how distant and cold Roger and David were to each other. I grew up on the Barnabas episodes when Roger and David are so close. It was a quite a jolt to realize they weren't always that way, but it was fascinating to watch.
I hated the way Roger treated Barnabas when he came home from his trip. It's understandable Roger
would want to believe his son but after all the seances, ghosts speaking through people, girls travelling through time, not to mention his own wife consumed by flames, you'd think he'd stop being so skeptical of the supernatural after awhile.
[spoiler]And who did Roger think he was, threatening Barnabas that if he didn't apologize to "poor David" he wouldn't be welcomed in HIS house? Excuse me, but isn't Collinwood officialy ELIZABETH'S house?[/spoiler]
