"Father! Our family heirloom is missing?!" It's clear on James's look that he is still in shock that the object he has been eyeing for had been stolen by someone.
His focus is all about the family heirloom that he did not notice that the brother he has been jealous of since young is still actually alive and is sitting across his father.
James didn't wait for his father to reply and just walked his way in front of him. James put his grip on both of his father's should and ask him the same question again. "Father, is the family heirloom really missing from the old mansion?"
Just like Arion earlier, James is waiting for his father to say that he is joking, however, the look on his father's face is enough to know that he is not joking about the family heirloom.
