Originally, I thought the copycat did it to show the viewer a possibility of how Rudy could have gotten his intel.*g* But now I'm not so sure anymore. Also, the show is structured so symmetrically - two fathers for Dexter, brother/sister with Dexter and Deb and Astor and Cody - that another sibling from the biological family turning up as the counterpoint to Deb would fit. It would also explain thy the bio-dad let him in and close enough to get drugged.

And as you point out so correctly, it'd fit with the credits, with all the shots of Dexter eating, chewing, enjoying his food.

Clearly, we have the same evil brain. (Though thankfully one not served as dinner to Clarice by Dr. Lecter.)

As Dexter says himself: No wonder he's been suppressing emotions all along, if just the flashbacks and shadows are what he would have felt all along otherwise.


It's yet another irony that Doakes makes his "you don't feel anything" accusation at a point where emotions are finally breaking through (I think given his reaction to the danger to Deb it's clear that Dexter, no matter what he calls it and how unable he's to show it in every day interactions unless he's playing all normal boy, does love her).
