{Champagne's POV}
According to Duke, they did not tell Irene that her brother had been kidnapped. They just explained to her that he went somewhere with someone. They didn't want to outright tell her that her brother had been kidnapped just some weeks after her mother was just kidnapped. It'd be too much for her.
It was safer to tell her the truth after they found Sherlock and he was back home by her side. That way she wouldn't feel the impact of the news too much.
Getting home, it's already past four, Giovanni and Mary were trying their best to act normal while Renny was sitting on the ground coloring in her book.
At the sight of us, Giovanni lets out some words of thanks in his mother tongue and Mary is praising God on her knees with tears in her eyes. She must have been going insane with worry.
