No, I don't think we did get to see what happened to Kristen after she left Salem. But, apparently, the whole story that Kristen told Brady about what happened to her, (about her being kidnapped and taken to some island where she was badly mistreated -- and Stefano felt sorry for her and rescued her, which is why she is so indebted to Stefano), was pretty much the truth --- at least according to what she said outloud to herself in one of her soap-opera-talking-outloud-to-herself moments.
PS DL, I also get so fed up with the local news interruptions of daytime programming --- so I just routinely watch Days on the Soap Channel now, so that problem is over. And, I also record the programs on my DVR (TIVO) so that I can watch the show whenever it's convenient, and more importantly, fast-forward past all the crud that I don't want to watch. This does always make me one day behind in the episodes, but except for conversations here on FORT, it really doesn't matter.
