'Dexter' Season 7, Episode 5 - 'Swim Deep' Recap

Not much action this week on "Dexter," unless you count a slow-motion recount of Isaac killing some rival gang members. On that point, it looks as though we have this season's Big Bad, as Isaac has proven himself to be a skilled killer who is probably not going away anytime soon.

That's bad news for Debra, too, as she is on Isaac's list by association. That, along with coming home to find Isaac sitting in his living room (luckily, Dexter evades), prompts Dexter to put himself and Deb up in a hotel for a while. Deb is understandably unhappy, and starting to see the level of danger that Dexter is always in and seems to have gotten used to.

Deb's upset enough without that, as she discovers that Laguerta is on the Bay Harbor Butcher case. Watching her (profanity-laden) breakdown in the elevator is another indicator of how much better equipped Dexter is for dealing with this kind of thing. Deb can't take all the lying, and the stress of knowing that you're one mistake away from being caught.

That leads Deb to tell Dexter that she just can't side with him on this. What will this mean for their relationship? Is there much of one left at this point? Is anyone paying any attention to this season anyway?

A good chunk of the episode was dedicated to more Hannah McKay, and it's clear now that whatever plans the writers had for this storyline seem to be falling totally flat. There's some clear flirtation between her and Dexter, but it doesn't live up to the likes of Dexter's past love interests... at least not yet. That's no fault on Yvonne Strahovski, who is doing a fine job. There's just too much exposition going on here.

Dexter does find, once they exhume a couple of the bodies that Hannah is there to help them locate, that Hannah is more of a killer than she let on, as she stabbed one of the victims to death herself. If that doesn't spark Dexter's interest, I don't know what will.

So with Louis out of the way (and Dexter now aware of the fact), what poses the greatest threat to Dex this season? Is it Isaac, or is it Laguerta? Or will Deb finally crack under the pressure?
