I think Jennifer is doing exactly what the character calls for. She is majorly stressed by Barbara's disappearance, by Iris's appearance, and by Emily's over-reacting and hateful attitude. Not to mention the bad memories associated with even being in Oakdale at all.
She looked lovely today with her hair pulled back...she was enjoying herself, laughing, smiling, and being playful with the kids and Allie until Henry called with news of Barbara. Then, as the script would call for, she was stressed again....and worried for Barbara and Will.
I think Jennifer is doing a fantastic job. I enjoy every moment she's on. I hope she and Will stay to the end. I love them with Casey and Allie.
