Just found a site with some info on the young girl Jessica who played Krystina in Dynasty on the IMDB Board.

There are no pics of her, but a small list of other TV appearances she did in the early 90's, including Dynasty and Dynasty - The Reuinion.

Not a great help i know, but there was some questions a while ago on the board about any info on Jessica, it doesn't mention anything recent.

Hope any of this is helpful.
