This is the 6th-season finale of Dexter. In the episode, Dexter and the Homicide department try to stop the Doomsday Killers from committing one final murder, while Debra deals with a new emotional situation. Based on the preview given by the last episode, it seems that Travis assumed that he have finished all the necessary tableau for his "end of days" routine and also think that Dexter is dead. Aside from that, it also show that Dexter's son will be his next target and will be used as the sacrifice for his last stage of his so-called end of days. There's also a news that this season is not the last of Dexter and they have renewed 2 more seasons for this show. Aside from that they didn't confirm anything yet if the 2 season is the last for it. That's good news huh!? Well watch Dexter season 6 finale online here on December 18, Sunday of 2011.
