After last night's episode, and more importantly the "Miss me, little brother?" bit the hamsters in my head began to turn the wheels ... I have a crazy theory :
What if Gellar is part of Travis's psyche/ his Dark Passenger ?
Now, I know what you're thinking :
But he's a real person ! He was an instructor at the University! He slept with that crazy professor chick!. Yes, BUT - she also says that she hasn't seen him in years. Remember, Gellar has also not been seen for a few years. Another thing, have you noticed that whenever they show a captive at the church, the captives never mention nor speak to Gellar ? It's always Travis they speak to. Even if you can hear Gellar speaking to Travis "He's ready". Also, at the scene where Travis is making flirtatious eye contact with the waitress, she does not address Gellar, she asks
only Travis if he wants more coffee (?). There was also something very suspicious about the scene yesterday where Dexter is trailing Travis and he conveniently ceases the pursuit right before Travis meets up with Gellar. Like Mattrick mentioned, Travis tells Dexter that he's incapable of killing another person, that it's always Gellar who's done it, but wasn't the former the one that hacked that fruit vendor to pieces ? Perhaps that's when his Dark Passenger assumed control ?
I started to think about this yesterday after seeing Dexter's dark passenger take form in the form of his deceased brother. If Dexter's DP can be personified by a different person, why not Travis ? Perhaps Travis met Gellar, Gellar died off screen / before the season started, but not before passing on to Travis his batshit theories regarding the Revelation.
Anyway, I know I don't have any solid evidence to back this up, but the part of me that has seen way too many film and tv show plot twists can help but wonder
What do you guys think ?
