Manager Claire furrowed when Janet didn't listen to her to stop Elder Collins. As a mother of two teenagers, Janet's behavior toward her first child; Alvin always disgusts Claire. She kind of understands what Elder Collins or the Collins family was going through.
Twenty-seven years ago, she was an assistant when Janet entered the entertainment industry. She had agreed that Janet having a baby at the beginning of her entertainment career will destroy her chances to grow.
However, none ever told Janet to send Alvin to the Matthews family or completely disregard her child. Since it was Janet's choice they had never butted in and focused on Janet's career.
Since Janet lost her mind after a simple call by Casper and took it further to Alvin, Claire doubted if Janet ever considered herself as a mother of Alvin, much less as a grandmother of a little boy.
