Seto seemed pleased, a smirk on his lips when he heard her answer, telling him how right he is. Though he guessed that he could continue to listen. Had nothing to do. But he wondered why she seemed so obsessed. He shrugged. Though Seto knew how it felt when he was confused as to why Yami seemed to be so important and among all that they had been through, why his fate was intertwined Yami's till the answers were clear. Seto then let it go. They somehow became friends and that was that. Nothing more or less. Seto however seemed aware that Yami was at the the opening between the Kitchen and livingroom. Just saying nothing.

Yami stopped at the opening when he heard Serena talking. Though confused what was being said, noticed some key clues that pointed to him. Paths being linked. Little Prince. Yami remembered those and the fact that last night that was what Serena called him out of being tired and exhausted. He didn't move nor say a word. Seto only spoke up. "Well. I wouldn't know what to tell you there and I don't even think that he has the answers. As far as I know he is as confused as you are." 

The pharaoh didn't intervene. Seto was right. Yami didn't know why. Didn't know why Serena was feeling what she was feeling, why she saw the way she did. What was he going to tell her? This was why he asked for Malik and Ishizu's help. To get a better understanding what was going on. To give Serena answers to her questions if the siblings could at all.
