The body of one of Dexter's previous female victims has been found, despite Dexter's having thrown both of the corpses into the ocean. A young Cuban boy had witnessed the previous night's events, and Dexter dismisses his colleagues' leads that could direct them towards him. Eventually, Dexter frames the husband, whose body is still missing, with his wife's murder. The witness describes Jesus Christ rather than Dexter. During this time, Rita dissuades her abusive husband, Paul, from attending their daughter's birthday party after he is released early from prison.

Did You Know?


Etorphine is a ultra-potent semi-synthetic opioid used for tranquilizing large animals, and is approximately 3,000 times more potent than morphine. It is synthesized from oripavine, which is a naturally occurring alkaloid found in the Oriental Poppy and the Iranian Poppy, but not in the Opium Poppy. It is only available for veterinary use, in it's hydrochloride form Etorphine is a Schedule II controlled substance and can only be ordered by a Doctor of Veterinary Medicine who has a general DEA license for prescribing controlled substances, and also has a special permit from the DEA to obtain Etorphine. All other forms of Etorphine are Schedule I controlled substances and the hydrochloride form cannot be ordered or dispensed by most DVM's or any MD's. As it is extremely potent Etorphine is not approved for used in humans, the lethal dose of Etorphine in humans is 30 micrograms (.03 milligrams) and because it is so dangerous to humans each vial of Etorphine also comes with a vial containing the appropriate dose of naloxone (a opioid antagonist) to reverse its effects in case of accidental exposure, even getting the powder on your skin is enough to cause a fatal overdose, it does not have to be injected, inhaled or ingested to be fatal.

Things Begin to Fall Apart!
28 December 2013 | by g-bodylSee all my reviews

In another fabulous, tense episode of Dexter, we see that the stakes are higher and that the tension is about to reach the peak after the incidents in this episode. The acting hasn't been better and the story hasn't been better. After the ending of this episode, I just want more and more. That talks about the quality of these episodes and just how good and addictive they are.

This episode, "Return to Sender" has Dexter staring more and more into danger. The Ice Truck Killer takes Dexter's most recent victim and puts him at the scene of the crime where the victim was murdered. Now Dexter must do everything he can to avoid being caught by his own police department.

Overall, this is a very good, thrilling episode. I liked the fact how now we get to see some things from Debra's point of view and we see some more flashbacks between the two. This episode is also about the relations between brother and sister and how they turn a little sour with this episode. I rate this episode 9/10.
