Hi Michel,
there's a bit of discussion in a thread over in the Bachelor(ette) forum too.I didn't see the first few seasons either so I don't know a lot of these people.
But Elizabeth is a kook. 
From reading some of the stories (like one on Deanna on our own front page here at RTVW) it seems there has been a lot of date swapping going on with a lot of the previous contestants.
___ dated ______ who previously dated ______ yadda yadda yadda 
for talking a lot? me? Jan 2010
