SPOILER! Entertainment Weekly's Michael Ausiello talks to The Good Wife executive producer Robert King about whether Alicia (Julianna Margulies) and Will (Josh Charles) will ever hook up. "[They have] one of the most complicated relationships… because it really is a friendship that doesn’t want to lose its friendship by going to the next step," King told Ausiello. "There’s an episode [coming up in April] that’s all about not knowing what a jury is thinking and it’s a metaphor for how Alicia and Will can’t get into each other’s heads. During this trial, they have to make moves, guessing where the jury is headed. Sometimes we see that they’re just completely wrong." (Entertainment Weekly's Ausiello Files)
