Hmh, hadn't thought of it, but I definitely agree with Cote/Ziva being polar opposites. I figure that Cote, and the Big Guys Upstairs, are the ones who've decided that Ziva should wear makeup and straighten her hair, for example. If anyone suggested to season 3-Ziva that she should spend half an hour (at least) straightening her hair every morning, she'd have... done something nasty.

As for the others, they definitely have qualities of the characters/actors. I think Abby has suffered changed so much from season 1 Abby to today's idiocy because of PP. The fact that Tony can't seem to develop past the whole frat boy image is undoubtedly at least partly because MW likes playing him(self) that way.
