And I think that comes down to the fact that Lindsay doesn't really bring anything to the show. If you talk with any of the other actors, they can go on and on about their characters' roles or their thoughts and views on things, or what they add to the show. In his last interview here, Hill was talking about how Hawkes gets all the complicated science stuff. Carmine talked about Danny being the "go-to fuck-up" and how that still comes up for his character. I could go on but I think that illustrates it--all of the actors have put a lot of thought into their characters, a lot of passion and complexity, and she just hasn't. It's still the same stuff they were talking about back in season two, which we should be long over. You don't hear Carmine talking about Danny being the "hothead" much anymore, or Gary discussing Mac losing his wife in 9/11. Those were things the characters were introduced with, but have grown from since. They're still part of their bio/background, but four years down the road, not still the first thing you think of when the characters are brought up in their current incarnations. With Lindsay, it always comes down to falling back on the same old, same old: "country girl in the big city," "breath of fresh air," a foil for the New Yorkers. Nothing new or interesting to say about her since the season she was introduced--three seasons ago--other than, of course, that she banged Danny.
