Rhea watched him closely. He was clearly on edge about something. She wasn't incredibly close with many in their pantheon. She considered very few of them close enough to be considered friends. There were those she held dear to her heart, such as her children (even if some of them may still hold grudges). But she also didn't make it a habit of making enemies of those she wasn't particularly close with. "Ah, I see," she said when he admitted something suspicious was up. "It wasn't Zeus, was it?" Rhea would never question Zeus. She was most loyal to him. She loved her children equally, but differently. In the case of her youngest, he was king and commanded respect.
