Vienna, Bianca's mother, was worried after noticing another woman sitting beside Bella's husband.
She mistakenly thought that Belial had called everyone together to punish Aengus for cheating on his daughter or something similar.
Noticing her mother's worry, Bianca leaned forward and whispered the real reason for the gathering.
Vienna's eyes widened as she absorbed what Bianca told her.
If what Bianca said was true, her new son-in-law was more terrifying, stronger, and more ambitious than her own husband.
Bianca exaggerated a bit, claiming that her brother-in-law was nearing the power of a Demon God, which made Vienna skeptical a bit.
Their Progenitor, the Demon God's power, was said to be unrivaled and world-surpassing, so the comparison seemed exaggerated—at least for now.
