That was on Halloween when I said this, and n*ggas thought I was crazy. All these people who laughed at me when I brought up the possibility of Gellar being apart of Travis' personality. Now y'all are starting to see my theory cone into fruition. There is NO way that Gellar was really in that church when Dexter showed up. Travis is just an extremely fu*ked up dude who probably k!lled Gellar and a.ssumed his entire identity. He's basically a 2011 version of Norman Bates.
You're probably right. They are giving all the hints to make you think dude is not really there. The only person that interacts with, or even sees Gellar, is Travis. It always showed travis doing the work, and gellar doing the planning. The only thing Gellar has done on his own was k!ll the sister while Travis was "knocked out". Travis probably got his hands on some of the guys journals or copies of his journals. The only thing that is making the police think there is more than one k!ller is the fact that Travis let that girl go in the parking lot.
However, the girl alluded to there being two people at the church. Or did she just tell the police that Travis was calling someone the Professor? They never interact with people at the same time........................
