I, too loved the Laura storyline, from its plot to writing to acting. Diana Millay was so good, especially when she took her characteristic defensive posture: head held up, eyes looking down, mouth closed tightly while speaking but with that smirky grin. But I have to add that my favorite Diana Millay scene wasn't from the present-day Phoenix story, but from the 1897 one, where she and hubby Edward verbally duke it out over who was the bad parent.
