After Cassy's burial, Alpha Fredrick stood outside with George in his arms. It wasn't like he wasn't affected by Rowland's disappearance but he just didn't want to make another mistake as he did with Rowland.
Due to his quest for his pack, he neglected his son which led to their misunderstanding. He never watched him take his first steps or say his first words. He was always busy and made his pack his first priority.
He wasn't going to make that same mistake again
He was actually waiting for the scouts he sent out to search for Rowland. It's been days now, but one of the scouts came back and he informed Alpha Fredrick that the rest of them would be back today.
They had been searching for Rowland non-stop yet there was not a trace of him or Della. Even Cassy's friend was also missing. But then, Alpha Frederick still had hopes of meeting his son as he believed he wasn't dead.
