This episode embodies many of the greatest weaknesses of the show. Allison is shown to be willfully helpless in the face of her psychic abilities, even to the point of psychopathy -- while in the grip of her compulsion, she does not care about the troubles or feelings of her children or husband, nor the consequences to them or to herself. Thankfully for her, she lives in a plot-driven universe which exists solely to reward her every questionable act, including a heinously illegal act toward the end of the episode which is forgiven on the grounds that her commission of the crime stopped the "real bad guys" from committing it first. (If nothing else, her boss -- the District Attorney -- should be tearing strips off her for her unthinking "ends justifies the means" cavalier attitude.)
It is worrying that Allison's total lack of thought or caring (she never once listens to her husband's highly reasonable objections, much less considers any other way to resolve the episode's central dilemma, and manages to go the entire episode without even learning of the secondary plot because she cannot be bothered to care for her own children) is *rewarded*. What kind of message is this show trying to embody here?
