I think Brooklyn Chase does a fine job as the new Dr. Laurel. I would be over the moon if Daphne Rosen came out of retirement to reprise the role, but as much as I might lament a viewing opportunity lost, I'm happy that her transition has gone smoothly and that she is by all reports content herself.
Yes, Brooklyn was a good Dr Laurel, but I think the striking black hair and the VERY large boobs that Ava has lend herself very well to the role. And she has a very seductive way about her, something that I think Laurel needs.
Having Daphne Rosen back would have been amazing of course, and I hope she is happy in her new life.
