Dexter struggles to distance himself from Miguel, who will be his best man at his wedding, and starts plotting to kill him. LaGuerta begins to believe that Miguel is Ellen's killer, and searches his car for forensic evidence after inviting him over for dinner. Miguel realizes that LaGuerta suspects him of Ellen's murder, and decides to kill her. When Debra starts avoiding Anton, Dexter tells her of their father's affair with his informant, Laura Moser, without revealing that she was also Dexter's biological mother. Debra discovers The Skinner's whereabouts, but he escapes when Quinn is injured. Dexter's relationship with Miguel comes to a violent end.
This is the eleventh episode of the third season of Dexter. Talk about a mind-blowing episode of Dexter! The last few episodes have been tense, but this episode increased the tension up just a notch. Miguel has a huge role in this episode, and perhaps many viewers will like what will transpire out of the relationship between Miguel and Dexter.
In this episode, "I Had a Dream," Lt. LaGuerta begins to suspect Miguel as Ellen Wolff's killer and now Miguel is at a crossroads. Meanwhile, Dexter is formulating a plan how to kill Miguel and blame it on the Skinner. Dexter also tells Debra about their father's affair and Debra is avoiding Anton.
Overall, this is another incredible episode and the ending is just excellent and deserving. The season started off a little slow, but it is about to end with a bang. I rate this episode 10/10.
