Season 6's season finale ended with the game changer to top all game changers on Dexter. Deb (Jennifer Carpenter) walked in on Dexter (Michael C. Hall) killing Travis (Colin Hanks). As expected, the Lieutenant of Miami Metro has had a hard time dealing with this horrific revelation about her brother. Yet, she hasn't arrested him and has even aided him in avoiding capture by planting evidence among other things atypical of her personality. Deb, who admitted to having more than sibling feelings for her adopted bro, has done everything she can to protect Dexter this season.
