If Patrick Duffy wouldn't have left, we would have had two years of a reconciliation between him and Pam, rather than just one. I'll be damned if they were going to drag out him and Jenna any longer, or Pam 'searching' for Mark..If Patrick Duffy had not left at the end of Season 8 then do you think they would have reunited him Pam? The reconciliation seemed tied into the Romeo and Juliet theme. Would Bobby have married Jenna? I think he would have been with Pam eventually.
