Unfortunately, he could only bristle in anger, unable to do anything. Even if he hadn't lost his authority, he wouldn't have been able to order the family to hunt a King mage down.
Then, the demon invasion happened and he got so busy he forgot about his grieving daughter and the murderer of his grandson.
However, when he heard the name and description of the boy with an extraordinary bloodline, he recalled what Helen had told him about Jack's murderer and realized both were the same person.
At that moment, he had sighed in helplessness because the family's plans regarding Max didn't exactly match Helen's desire for revenge. Thus, he decided not to inform her. But as luck would have it, she still found out.
"Father! Tell me, is this true?" Seeing his father not respond, she asked again.
Sighing in his heart, Grem nodded, "Yes, it's true."
Hearing this, Helen's eyes shone with such killing intent that the air around seemed to freeze.
