Kind of a confusing transition in story lines going on here. The Isaac stuff is seemingly over as far as Dexter is concerned, unless his new relationship with him that he made at the end will make him wanna kill that dude from the strip club. Although it appears they are setting up a little feud with him and the fire inspector guy who he thinks is the suspect. Everything else seems pretty secondary though. Quinn vs the strip club guy and even Laguerta's mission to figure out the Bay Harbor Butcher deal are kind of side stories, even though Laguerta's thing will probably get to Dexter's attention later on. Just sorta weird how that storyline with Isaac ended now.
And I seriously about cried when I thought Hannah died. I would've missed staring at her hot ass every week.
