I missed some of the start but they didn't really talk in the part I watched about her second run, just her first and her time at GL. She did say Gabrielle was her favorite character of the two because she was Gabrielle during such important times in her life. She also said that after she left OLTL the first time she would have to not cry around 1 and 2 PM each day because mentally she was trained to cry and cry while playing Gabrielle. When she went to GL she wanted to make sure she played a character who didn't cry (that didn't end up happening...).
She also talked a bit about just what it was like interacting with Andrea when she joined OLTL, as Andrea was a star and she was not. She mentioned Andrea not really wanting to share too much with her, and also not wanting to go and eat with her, as Andrea was in her own world and had an entourage (which Fiona teased her about a bit), but she did say that she learned a lot from Andrea about acting on the soap, about how you and the writers will eventually find the rhythms for your character, etc.
