While Dexter is very busy dealing with his own "Marla", astonished with how another person could see him and not look away, interesting side stories are developing. Debra is still having a hard time trying to face her recent past with the Ice Truck Killer, which leads her to make false assumptions. Rita's mother is becoming a nuisance (actually she "sees" Dexter but wants to look away) but Rita has manned up to her and defended Dexter/her relationship with him, causing mom to decide on "staying" in Miami! The hunt on Bay Harbour Butcher continues and more facts are revealed on the algae. Debra and the FBI Agent scroll down to the marina where Dexter keeps his boat as well, and they come up with the idea that this particular marina is too dark, so they furnish it with surveillance cameras. Dear Dexter speaks of his untold past to Leila, who convinces him to do some confrontation. They ride away together to find the only person from Dexter's mothers brutal homicide. Dex beats him bad, and he reveals his mother to be in a relationship with Harry!!!
I like Dexter very much, and I like the way they have turned the show. This twist is not bad at all, any other way it could have been lame but the writers managed a successful turnaround. I am looking forward to next week!
