Harry death theory (spoiler) Original Sin

I havent seen this discussed yet, apologies if it has been. As we've seen in this season, Brian has been targeting and killing off those who were involved in separating Brian and Dexter after their mothers death.

From the Original Dexter, we've known that Harry "committed suicide" by means of heart medication. We've always kinda based things off the idea that Harry couldn't handle who Dexter had become, so he killed himself.

Harry does not seem to be struggling with who Dexter is at all during Original Sin. In fact, I feel his support more than anything.

I truly believe it is going to turn out that Brian actually killed Harry all along - especially since Harry is the one who caused their mother to die in the first place. Harry is likely #1 on Brian's list.
