In last night's episode of CBS's The Good Wife, "Get a Room," Alicia (Julianna Margulies) and Will (Josh Charles) are forced to mediate with a former girlfriend of Will's, Celeste (Lisa Edelstein, House, American Dad!). Celeste tries to use what she knows about Will to gain an advantage, while Alicia agrees to play dirty to help their side. The mediator does side with Alicia, but she feels bad when he calls her out on her sneaky tactics.
Alicia is a "good girl," as well as a good wife, when the series begins. There has been a slow transition in her character to someone who can be a bit naughtier. This isn't necessarily a bad thing. Sure, she finds some moral grey area where there wasn't any before. But it also makes her seem like a freer, happier, more well-rounded person. Whatever else her relationship with Peter (Chris Noth) is, it is a bit suffocating for her. Seeing Alicia being truly happy, even if that means stepping on a few toes, is worth the price.
One can credit Will with much of the change. Finding pleasure in his arms, she loosens up sexually. Alicia may seem a bit prudish and repressed to most, but she is not that way when flirting with Will, as evidenced by the fact that she offers to dress in costume for him; an American Revolution costume, no less. Will is allowing Alicia to find her sexiness, and they seem to enjoy each other's company. It's really a win-win situation for the couple.
That is, it's a win-win unless Will is in love with her. Alicia's brother, Owen (Dallas Roberts), keeps trying to get Alicia to talk about her new lover, but she refuses. This leads Owen to figure out that Alicia is just using Will as a fun release, not because of a deep emotional connection. Sure, Alicia and Will are old friends, but she isn't fancying him for the role of husband number two. instead, he's a secret that she keeps just for herself, and that makes it even more tantalizing, but not so important.
Might Alicia be, at least in part, trying to figure out what causes Peter to stray? Knowing all the things he did, maybe her affair with Will is her way of living out some of that fantasy life and better understanding her husband. Or, maybe she just wants to get even. They are separated for now, but the circumstances of Will and Alicia's current arrangement open the door for a possible reconciliation later on. Both Alicia and Peter will have to find a way to forgive and move on, making the split two-sided instead of one.
