Harry Morgan: It never ends, does it? The maintenance.
Dexter Morgan: I don't mind it.
Harry Morgan: It's the one thing that never changes. The waves keep rolling in, wearing everything down in their path a little more every day.
Dexter Morgan: Harrison's coming home soon. I want to have the boat ready.
Harry Morgan: So life's back to normal?

Isaac Sirko: The Terminator!
29 October 2012 | by See all my reviews

I love the character development in this episode, esp. Isaac's. Man, he's bada**, completely psychotic and I think he will not be put down so easily. After all, he is the terminator. There is definitely more Isaac coming, and he may just turn out to be the best villain in the series. Well, him and Brian.

The plot is thickening, with Isaac's blood thirst, Hannah and her dark secret, and surprisingly Quinn coming into picture. I am loving how this season is developing, sometimes fast and sometimes slow. But so well connected.

I love Debra freaking out scene and how she regroups herself. I think it was her personal best cursing in the whole series. Ha.

Dexter still hiding facts from Debra, after putting her a** on line, is surely going to end the wrong way. But Dexter, being always protectful of her sister, does want her to 'swim deep'. And Laguerta digging deep into the Doakes case will definitely take an interesting turn. I can just feel it.

This season is becoming more thrilling and suspenseful with each episode. Hats off to the writers. What a comeback!
