Now 1968 is fresher in my memory than Leviathans. Did they really give no clue as to how Jeb was somehow mixed up with Bradford and Victoria? Other than getting them killed somehow?
We know Leviathan people were around in 1795/6/7, whatever....because that's where Barnabas met them. Is there any hint of an implied reason that their being there at Collinwood back then led to Jeb offing PB and VW? They throw a lot of extra relationships into Bradford's past, indiscriminately. It just suddenly turned out that Eve knew him, too....
It was pretty short-sighted of Barnabas to send PB and VW mark 3 out the front door of Collinwood, assuming that since they said they were making their way out west, they would get there. No reason to think they weren't nabbed a few minutes later and taken back to gaol. Barnabas was naive about problem-solving at this point. He was new at solving other people's problems and screwed up a lot.
So now it's Barnabas' fault what happened to Peter and Vicki? I agree that Barnabas can mess up a lot when it comes to changing (or not changing) history. But I think it's unreasonable to expect him to be able to foretell what may or may not happen.
I mean, Barnabas had absolutely NO reason to think that anything was going to happen to Peter and Vicki. I mean, I'm sure he believed that they would be smart enough to avoid the authorities and keep out of sight as they left Collinsport. He had no idea that a monsterous race of super beings existed at this point.
I still don't buy Jeb existing at all in 1796, but I have started a thread where I speculated that Barnabas' second trip back to 1796 may have led the Leviathans to rise to power and screw up Peter and Vicki's happy ending. Maybe it wasn't really Jeb but another Leviathan who looked like him that did the damage. Who knows.
I have reached the point on this that I agree that it probably is best just to ignore this insane plot development and pretend it never happened.
