Looking at the situation with Isla Mamet, it seemed she had already grasped the mystery within.
Joyfield chuckled and said, "Mrs. Mamet, if I'm not mistaken, after your daughter became pregnant, you ran tests and should have discovered that the fetus was not a virus carrier. At that time, you must have suspected whether the baby really was Gem Atkinson's?"
Yes!
She had monitored the growth of the Beast throughout, so she knew better than anyone what a virus carrier fetus should look like.
But after Tiffany Mamet got pregnant, the tests showed that the fetus surprisingly wasn't a virus carrier?
She indeed had her doubts.
But at that time, she also thought that Gem Atkinson, already racing against death, couldn't possibly be joking with his own life. Besides, she, Isla Mamet, had personally witnessed Gem enter the room. Therefore, she would rather believe it was a stroke of divine luck that allowed Tiffany to accidentally select a J sample that wasn't carrying the virus.
