- Professor Gellar, to be played by Edward James Olmos, is someone that all of Miami is seeking out. He becomes a big person of interest in some crimes that are being committed in Miami. They are probably the biggest crimes we’ve ever seen on this show. We’re going toward a different kind of serial killer than what we usually see. This is someone more in line with the Zodiac Killer…. He kills people with great conviction. This is probably the first serial killer we’ve had who thinks he’s in the right. Professor Gellar definitely feels like he’s killing for a reason, and Dexter is very, very curious to know what exactly that reason is, and to try to understand it in some way. It’s very intriguing and baffling, and it doesn’t make sense to Dexter. For more spoilers on the upcoming season, click the link of the source. - Source: Entertainment Weekly
