After tonight's episode of Dexter, there are only three episodes left for Season 7. "Helter Skelter" offered a notable body count and what seems to be the conclusion of one of the major arcs for the season. (Spoilers ahead!) "Seems" is key here as there are still a couple of key characters in play related to the Brotherhood, George being one of them. Nadia another. But something tells me Quinn will the one to clean up that mess, or else continue to splash around in it.
Deb loves Dexter the way Dexter loves M&Ms
After last week's emotional confession from Deb to Dexter about her feelings for him, Dexter decided he'd make light of the situation than face it head on. He didn't brush it off as a joke, but he did try to downplay the enormity of the situation and act as though this kind of "love" Deb speaks of is perfectly normal and nothing to worry about, even comparing it to his fondness for M&Ms. Obviously we all know that's not the case, and Dexter probably does too. He may have a Dark Passenger to deal with, but he knows what love is and I have to believe that somewhere deep down he recognizes the hugeness of the situation. So, either he's just not ready to deal with it or the writers aren't. Jury's out there. But for now, the major awkwardness appears to be abated enough that these two can get back to working together. And speaking of working together…
"Even a man dangling from a cliff will stretch out his hand to his worst enemy."
Isaak and Dexter had their little heart-to-heart last week, which had Isaak confessing to the romantic nature of his relationship with Viktor. So now he and Dexter are friends. Kind of. Not really, but kind of. Isaak's being pursued by two guys from the Brotherhood and he thinks he needs Dexter to help him track and kill them. Personally, I think given Isaak's knowledge and resources, he could have found someone other than his enemy to murder these two guys, especially considering the reason he's on the Brotherhood's list is because he was trying to kill this enemy he's now enlisted to help him. But he went with Dexter and it almost worked out. He kidnapped Hannah as a way to get Dexter on board with this plan and that served the double-purpose of getting these two killers and teaching Dexter a life lesson about love.
Dexter killed the first guy at the shooting range in a pretty great and totally creepy scene as the camera had us so distracted by the shooter's target practice that we didn't notice Dexter snuck up behind him and stuck a knife in the man's back until it zoomed out. Clever! The next guy was killed on a ship that Dexter lured him to. Killer thought he was tracking Dexter until Isaak popped up and shoot him in the head.
At this point, Isaak could have taken Dexter out, but he held up his end of the deal, though who knows if that would have stuck. George showed up and shot Isaak, leaving him mostly dead and ran off to be dealt with at another time. So in the end, the two hired killers (now dead) were unnecessary as George got the job done himself. Dexter did Isaak the honors of boating him out to where he dumped Viktor so the two could be "buried" together per Isaak's final wishes. And on their trip, they talked about love because Isaak witnessed Dexter not being able to tell Hannah how he felt. It was an odd moment but one that set up Dexter's sit down with Hannah to confess his feelings for her.
So, Isaak is dead, which presumably wraps up Dexter's involvement with the Brotherhood, assuming George doesn't come after him. I don't think he would though. He has no reason to. And while it's possible Dexter would pursue George, I wouldn't be surprised if he didn't and it was Quinn who ended up killing him. Quinn's interaction with George tonight involved pummeling his face after finding out George made Nadia sleep with him. So I'm thinking Quinn will be the one to deal with George.
