Plenty of shows have lasted with revolving cast members. The main ones that come to mind are Law and Order and ER. Yeah, the ratings and demographics drop, but there still is that draw that brings people in for the nostalgia factor. I don't see the show ending anytime soon, especially for it still leading in viewers in it's 11th season.
I thought I read/heard somewhere that episode 23 was going to be called Wind and the Willows. So does this mean that Cath's farewell is going to separate from Squeegie or whatever his name is? I really hope so, because I'd rather Marg get a fair and strong exit rather than it being a back story of "By the way, I'm peacing out of here, good luck catching him!"
As for how she leaves, I'm really hoping that it's the casino route. We've seen burnout and death, and I'd love to see her go do something that she really likes and knows she will be good at. Plus, I feel like this opens the door for a one time return way down the road. Imagine how the team (Nick, Greg, and Sara, if Jorja is sticking around this time) would react if a body turned up at her casino. Imagine the "like father/like daughter" implications. They could also go to her for advice on a case. Plus Vartann could either stay or go, too.
We'll see, though. It's just so hard to believe that in less than three months Marg will be off the show.
