Eight years later, 'Dexter' is returning for a ninth season

They could recon a bit.  Logan shoots Dexter in the head and the rest of the episode is a dream.  The season was reasonable good prior to the scuffle between Logan and Dexter.

This means Batista can eventually confront Dexter.  They could work on Harrison as Dexter-lite.

And Bobby can then step out of the shower.

Right.  Michael C Hall like Bret Spiner and Harrison Ford wanted to stop being known as their popular character so much they do not mind killing off the character and damaging the overall story.   

Killing a totally good person is not something Dexter ever did. He made some questionable kills of three morally mixed individuals over the series. He had angst about one of them. And, there  the kill was arguably in self-defense.  He killed some thuggish guy in a bar bathroom with no idea of his previous bad acts, and a crooked ex-cop.  Otherwise he killed murderers.

A dream of a a few hour sequence is much better than a dream of an entire season where the dream included elements not relevant to the dreamer.  One is more plausible than the other. I would prefer a little lameness to counteract a bad ending.
