So oscar ardiles is going to be in Sunday's episode.  If I'm not mistaken, he is the first returning past character since the "New Beginning" started.  Obviously, I'm not including the main cast members, Jane, Lisbon, Cho, Risby, Van Pelt and now Abbot and Fisher and Wiley if you wanna throw him in there.  So it got me thinking, do you think other past characters will return?  If so, which ones?
