Dexter Morgan was born in blood. He witnessed the beyond brutal butchering of his mother at a young age and the man he is today is directly related to that event. Now his biggest fear is that Harrison will turn out the way he has; Dexter fears that he too was born in blood through the killing of Rita.
We see Dexter at a mommy-and-me type event with Harrison. There is a scratching incident and the other moms suspect Harrison to be the culprit. But Dexter does not want to believe that his son is capable of hurting others. The truth is Harrison is still just a baby and a shrink assuages Dexter’s fear and guilt by saying he is a normal baby boy and shows no signs of aggression or violence. Dexter couldn’t be happier.
At the end of the episode we see a protective and defensive Dexter walk by the other moms and say there is nothing wrong with his son and imply that he wouldn’t scratch another child. In what was a perfect ending to this story the camera begins to pan away as Dexter is putting Harrison in his car seat and we hear a loud “ow.” Harrison was the scratcher all along, but this is hardly a sign of deviant behavior and is pretty typical of a 10-month old.
Also important to point out is the fact that Quinn, even after being placed on unpaid leave by LaGuerta, won’t quit in his investigation of Dexter. This is becoming even more reminiscent of Sgt. Doakes. What is so interesting is that Dexter works all day long with cops and only Doakes and Quinn have suspected him of being off. This ended in the death of Doakes and it can only be assumed that Quinn will meet the same fate. Granted Doakes and Quinn are right, but we don’t want to see people checking up on Dexter, we want to see him left alone.
As for now we’ll have to wait and see how it all plays out, but this season is shaping up to be even better than the last (a feat I never thought could be accomplished). Where Dexter will end up is still unknown, but the adventure of getting there couldn’t be more exhilarating.
