Dexter wants to know why Hannah is back in Miami but Deb wants her gone, and Zach is eager to learn the Code from Dexter.
Dexter and Debra's days are getting more uneasy with Hannah's return. The former killer girlfriend of Dexter is back in Miami and is married again, prompting Dexter to track down Hannah and find out what she's up to in the next episode of "Dexter".
Learning this, Dr. Vogel says, "Two psychopaths together... never a good mix," but advises Dexter, "Before you take matters into your own hands, consider all the consequences of those actions." Deb, on the other hand, asks her brother to get rid of Hannah.
In the meantime, Dexter agrees to take Zack as his protege and teach him the Code, but first tell the young sociopath to wait and be careful.
"Dress Code" will air Sunday, August 11 at 9 P.M. ET/PT on Showtime.
