When Zachary Garred first came on the show, I looked for pictures of him to see if his hair was real or a wig. As far as I can tell, that is his real hair, but something has been done to it to make it look more wig-like (why, why?). I think it's that pageboy style that makes it look so false. If you're interested, here's a link to his photo gallery at IMDB.

What I can't understand, however, is his motivation for being in PC. If he'd started eating the cornbread and mac and cheese once he was alone today, then at least we'd have known he was a phony. (But, of course, that would be showing rather than telling, so . . . . TFGH.)
