I only wish Grayson Hall had given up smoking sooner. I always wince when I see her with a cigarette in her mouth.
I think on soaps in the era of the 60's, only BAD characters smoked, and perhaps they wanted to present Julia as a bad girl (remember, she was slated to be killed off). Once the show returned from the past, she was morphing into Barnabas' friend/confidant, and they changed her persona by mostly eliminating the smoking. She was only smoking in this scene because of extreme nervousness and stress.
Love, Robin
