After getting back in his old habits, Dexter now has to deal with his long-lost son (who lost his blond hair, apparently). The search is one to find the spoiled brat he butchered, and of course he's ahead of the game...
Finally, it's back to the real Dexter, one who's speaking with himself and who sees his dead relatives (his step sister). She's constantly telling him how he destroys people. But considering how he gets taunted (quietly), he might just destroy himself...
For the rest, the episode was OK. It did touch on Native relationships (Senecas) and how tense they can be. That's something we hardly hear about. However, I bet that the rich guys (the petro-chem magnate and the one who lent the chopper) are guilty of something, like the kidnapping of the young woman we sometimes see.
Final rating: 3.1/5 (nothing out of this world)
