The romantic scenes are what cause me the most anxiety. You could talk to Mary [Mouser] about this because she and I are such good friends. When we had our first kiss scene in season two, they were asking us, "Are you ready?" My heart was pounding, I was shaking. It just feels weird to go to that place, because we're such good friends.
