This script was written pre-Brenda/Shannen. I read somewhere that the last part was changed and Brenda was added. I read that Brenda arrives at the airport with baggage in hand and looks up at the welcome sign.
The sign displays "Welcome to California".
Of course, the script is always subject to change. Most of the script will stay the same but the writers may or may not change the capacity of Shannen/Brenda's appearance on the season premier. Either way...I can't wait!!
