Abyss and Hardy were fighting regularly after the RVD angle, but now the storyline is Hardy set up the RVD angle. You could say we never saw the stuff on camera in that one angle, but what about all the other brawls and matches (like every house show practically) in the last two months?
Well if you want people to make an emotional investment in someone, then you have to keep an element of logic involved so people will want to see what happens. The old it doesn't have to make sense scenario is the rubbish and is one of the reasons why WWE and TNA aren't exactly flying on PPV.
The Dixie signing the wrong contract thing is obviously something that would be dumped by any court in the land, however at least they tried to explain it and add some degree of logic to it.
