I think he always had some degree of humanity, but working for Internal Affairs made a bit of a politician out of him. Just a thought--I'd like to see it where, if he finally came back (licks chops hopefully), they'd make him into more of a cop again, one way or another. I can imagine that being a paper pusher and being Yelina's stand-in for Horatio would make him mean and ornery.
Oh well. I guess we're just going to have to make things right in our fanfics, right? image

And hey. He can wear anything he wants (or nothing at all), and I'd definitely watch. (Besides, he might be hiding another mole!)
