Upon hearing Caleb's words, Xaviera felt a surge of heartache. She originally thought that Caleb was tolerating the Drew family so that he could gradually dismantle them, causing their eventual collapse.
However, when Noah mentioned the identity of the maid, Xaviera realized that Caleb had planted his own people in the Drew family years ago. Even Noah hadn't detected this, which meant that Caleb had been preparing for revenge since long ago.
Ten years prior, Caleb had founded the Mamet Corporation, and from then on, the Drew family had lost their qualification to compete with him. At that time, the Drew family had already lost Winni, and had begun to decline; but these changes were subtle, so Caleb had become guarded against the Drew family, but he never took action.
Caleb looked up at Xaviera with a mournful expression and a bitter smile, "I guess I still had some illusions about them, but they never took me seriously."
