As Shock Waves Spread, "The Good Wife" Takes Stock of Grief

Another of Will voicemails is central to "The Last Call," an ambiguous, terminated scrap of a message that will forever be the last communication between him and Alicia. It's nothing, really: a quick hello, a jumble of background noise, a pledge to call her back later, and then nothing. Alicia's finger hovers over the "Call Back" button on her phone, as if Will's death is a misunderstanding that might be cleared up, a cosmic wrong number. But instead, she spends much of the episode trying to clear up the mystery of why Will was calling her, envisioning scenarios both romantic and nightmarish, refreshing the pain of his loss because she knows that when it stops, he'll really be gone.

Others deal with Will's loss in their own ways: Diane Lockhart (Christine Baranski) mourns him and then memorializes him by cutting loose a client who couldn't be persuaded to wait a decent interval before getting back to business; Kalinda toys with giving Will's killer the means to end his own life in jail, then deepens his agony by driving home the hurt that he's caused; even David Lee (Zach Grenier) manages a brief fit of humanity before returning to his normal role as scowling attack dog.
