I think that perhaps you might want to give Jasika and Fringe a chance concerning this recent development. The show has not let me down with its continuity or fringe science before and I doubt it will with this coming season. When I first saw alternate Astrid I knew she was going to have some form of autism based on her behavior. I just knew it, and lo and behold the writers/pr/actress herself have confirmed it. I think the portrayal will be accurate. I hope the portrayal will be stellar.
