Paget signs a deal

[klutzy-girl.livejournal.com]

Brewster just closed a deal to return to the veteran CBS crime drama, and she will be in almost every episode next season. But Cook, whose option for next season was not picked up, will be gone after wrapping her character J.J.'s storyline in two episodes early next season.

I hear Brewster's pact is for 10 out of 13, which means that she will be in nearly every episode. The actress had been approached to continue as a regular on the show but for a reduced number of episodes; now the reduction seems to be pretty small.

Wait, what is this about 13 episodes? Aren't we getting a full season? I'm confused now!
