Lt.Laguerta

(S04E11) "Blood tech, husband, father, serial killer and now, Kyle Butler extortionist? Which one are you?"
"All of them." - Harry to Dexter

It is always fun to watch Dexter struggle over his various roles and purposes in his life. He's become a juggler learning how to add just one more ball to his act even as he's trying to keep them all up in the air.

This season, he's had more than ever before in a single season. He's a heavily armed Rich Little and adding extortionist to his list was a real smart move until, of course, Arthur gets the better of him.

(S04E06) "We both have skeletons, which means we both get a closet to keep them in." - Dexter on him and Arthur Mitchell, the Trinity Killer

Now that Dexter and his faithful followers have discovered Trinity's true identity as a family raising, student teaching, hymn congregation leading all around nice guy, it's made him twice as creepy. The fact that he can turn such a blind eye towards causing so much painful mayhem and in the blink of that eye pretend that everything is all rainbows and jellybeans twists my spine into a monkey fist. John Lithgow has not only reached into the bloody depths of this depraved character, but he's done a marvelous job of walking around in his skin, both figuratively and (I sure hope not) literally.

Now that Dexter is on the hunt, he seems more reserved, held back and less willing to pounce on his weakened prey. I'm sure part of him feels the need to put this man out of our misery and avenge the attack on his sister, but now he sees him as a mentor, a role model, a zen-like Yoda who can teach him how to strengthen his mask while he's doing the bidding of his "Dark Passenger." But will this moment of philosophy for madmen drag things down to a screeching halt?
