Dexter, Season 6

Dexter:
[Voiceover: Wolves come in many forms. Some have big eyes, the better to see you with. Others huff and puff...while others hide in plain sight... I should know, because like it or not, I'm one, too. That's never going to change. And neither is the fact my little lamb is becoming a little boy. Walking, talking, listening... As much as I want Harrison to stay this way forever, from now on, the wolves in his life have to be the stuff of fairy tales. I can no longer allow him to see the real me. Only the version that's make-believe - it's the only way this story gets to have a happy ending.]
