Q: What do you love most about Rhetta?
A: Well, I certainly love the friendship and the relationship with Grace [played by Holly Hunter]. I also love the scientific aspect and her flair with science. It's not something I was ever really good at, but something I've been interested in all my life. So it's great to play with that and indulge that part of my affinity. I'm a bit of a layman physics junkie. I don't really understand it, but I love trying to understand it.
