Televisionista: Is He Or Isn't He? "Desperate" Art's Sister Exposed!

In the closing moments of last week's episode of "Desperate Housewives", Lynette Scavo (Felicity Huffman) uncovered what seems to be her new neighbor's dirty little secret in the basement and thank goodness, it was not one of the Applewhites.

A wall plastered with pictures of shirtless boys in a basement filled with arcade games and toys belonging to a suspicious man can easily brand someone a child molester. But, is Art really a pedophile? After all, the man takes care of a sick sister. If he is indeed a pedophile, is she unaware of his deviance? Or is she an accomplice?

Lynette suspects the worst and she tries to get the police to concur. But, by the drama's Christmas episode, she may change her opinion at which point it may be too late to prevent a protest organized by the neighbors. Emergency will be called and a woman will go into cardiac arrest. Is it Art's sister whom we finally get a glimpse of in Sunday night's episode?
