9. ABOUT LAST NIGHT
Dexter starts to fear that Miguel may have strayed from the newly taught "Code." This concern starts to put a strain on their friendship. Meanwhile, Debra's new boyfriend Anton is confirmed to have been taken by the Skinner, sending Debra into a furious search. Not only for Anton, but also for his potential killer.
10. GO YOUR OWN WAY
Dexter feels like he's making a deal with the devil when he feigns civility around Miguel after his duplicitous ways. Finding himself in a series of chess-like moves against his former friend, Dexter hopes that Miguel doesn't get the upper hand.
11. I HAD A DREAM
Dexter has to figure out a way to remove Miguel from his life for good. But how can he manage to do this when Miguel is not only a highly placed D.A.? Meanwhile, Debra finds a new clue that brings her even closer to catching the Skinner.
12. DO YOU TAKE DEXTER MORGAN?
With Miguel out of the picture, Dexter's focus shifts to calming his emotionally unstable brother, Ramon. Upon easing Ramons concerns, Dexter can finally breathe again. All that stands before him now is his wedding with Rita...until he's met with yet another deadly surprise. Meanwhile, Debra's informed by Batista that she is going to receive her detective's shield, but is instantly blindsided with information that could potentially derail her promotion/
