If Janet had even once told him to ignore Casper's threat and focus on Zane's safety or teach Gianna a lesson. Alvin would have stopped Casper from releasing the news so that Janet wouldn't be troubled.
But it was useless when Janet cared about nobody but herself. Casper will keep using it against them. So he was ready to face the reality.
"Mrs. Wilson, why should I compromise my son's safety for you?" Alvin taunted Janet for expecting him to listen to her.
He wasn't going to suffocate Zane with security or trouble Anya who wanted nothing but a normal life for Zane. If Janet continued to irritate them, he might end up revealing the news himself.
Janet felt like a bucket of cold water poured over her. She had no ground to reason with Alvin other than, "I-I gave birth to you." Her voice quivered.
That's what Alvin hated the most. If he could change that fact, he would have done it a long time ago.
