This is what I think.... the original casting of Lauren's dad was to be Peter Fonda. I think J.J. gave Lauren's Dad a bigger part in the show because of Peter Fonda playing him. Just as they were about to begin taping he backed out because of something that conflicted. So they had to put a filler in his place. The script was already written with Peter in mind so they were stuck. I don't think his role would have been as big with a no-name playing the part.
Anyhow, back on topic.... I think he's in the picture because I think he's the reason Lauren went to the "dark side". :starwars: He made sure that she was never field-rated which p*ssed her off. I suspect there's something else there too, but what that is... I'm not sure yet. Only time will tell.
