[climbing on soapbox]
It caused me physical pain last night, hearing Wilson call his beloved friend a drug addict. And put us back to square one; I'd been so pleased, the week before, when Wilson hadn't argued with House's 'Vicodin as leash' theory. I'd believed that Wilson finally, finally was undergoing a change in his perspective of the pills. And last night, of course it didn't help when House referred to himself as a "doctor with a drug habit." I know--how they, and we, view the Vicodin pretty much depends on who's writing the episode. So much for continuity in such an important aspect of the character, and the show.
