I was shocked they had Deb find Dexter killing Travis. This was written and shot before the show was renewed for two more seasons so I had assumed that they'd only have her find out once they knew they'd have more seasons. Now obviously with 2 more seasons left then next season they'll have Deb wrestle with this revelation and find out she's kind of ok with it. Then season 8 things will spiral out of control and Dexter will be outted and she'll be forced to be the one to track him down. And the show ends with Dexter either dead or in prison.
