After learning about Jiang Desheng's incident, Old Master Jiang had already arranged for someone to clarify the whole sequence of events, and it wasn't until he saw the dossier that he understood the things his "good" son had done behind his back.
After blowing up, Old Master Jiang wearily waved his hand at Jiang Linyan, "Take your mother upstairs to rest. As for your father's matter, let's wait and see what happens before making any moves. Acting rashly will only confirm the evidence."
Upon hearing that Old Master Jiang hadn't given up on Jiang Desheng and wouldn't ignore him, Madam Jiang secretly breathed a sigh of relief. It seemed that what Jiang Desheng said before he left was true, only Old Master Jiang could save him now.
When Jiang Desheng was being taken away, he whispered instructions to Madam Jiang.
