Storyline Explanations Needed?

What storylines in wrestling did you think deserved an explanation for why they happened, yet one was never offered?  For example, I was like that when Owen Hart turned heel after his brief face run in late 1997-early 1998, then he joined the Nation Of Domination for no apparent reason.  

I heard they were going to explain it on their YouTube show, Being the Nation, but then after filming it they were told that YouTube wasn't invented yet and just scrapped it.  Hopefully the footage is still around in their collection somewhere.
