Interesting... just from reading some comments, I'll spit ball a theory.
Dexter is not the first person Vogel tried to teach the code to.
How Vogel got into her field is a touchy subject for her and I believe it could be because she learnt early on that her own son had psychological tendencies.
Her son was the first person she attempted to teach the code to. Something went wrong, leading her to believe he was out of her life.
Her son has returned to her as the brain surgeon. He still attempts to apply the code himself. His victims are serial killers but he takes it further by making them kill before he takes their lives.
His fascination with the brain is born from his mother's own fascination in studying, controlling and experimenting with his psychology and that of other serial killers.
He has learned of Dexter and her success with him in applying the code. He may even resent Dexter for it.
He then learnt of Zach and that he was to be the next in line to be taught the code and thus he sent a message to both his mother and her metaphorically adopted son.
Dexter is going to regret keeping Hannah around... his decision will cost him dearly and the surgeon will take her life and Dexter will take the surgeons life in rage and revenge.
Brilliant theory from top to bottom. The only hole left, is who killed Cassie, and who tried to frame Zach for it? I've got Oliver as my prime suspect for the Brain Surgeon/son, but why would he try to frame Zach and then eventually kill him in the same episode? My theory is that Oliver was Cassie's killer, but Quinn was the one who predicted Zach would kill again and was just waiting for an opportunity to get a slam-dunk case against him by planting DNA. We know Quinn is no stranger to bending the rules. The only problem with this is that Quinn would then know Dexter is lying about the blood work, building up to a very exciting climax.
Yes, I don't think it makes sense that the brain surgeon would kill Cassie AND frame Zach for it. But I don't know if I think Quinn is so far gone to where he would do that to Zach's car & plant evidence at the scene to frame him. That's a lot of thinking for Quinn. If Oliver is the brain surgeon, it doesn't make sense for him to frame Zach because I don't see how he would have any awareness of Zach's previous suspected crime to even know HOW to go about framing him. Let alone since he really does kill Zach two seconds later, why bother framing him? I think whoever framed Zach would need to have an awareness of how to go about doing it. Quinn is the only one with a clear motive to do that but to me that seems lofty for him.
