Seto raised a brow as the rest of his face gave him the look of 'really?' Seto wasn't a trusting guy like the rest of the nerd patrol. Even then it takes him longer to trust anyone than it would take Yugi's friends to. Heck, he is still needed to figure out Cora. He knew nothing about her other than her dueling style and the goddess that blessed her. That was all. "Not that I'm worried." 

Seeing Yugi wave awkwardly, Seto looks over to source to see Cora. You could say it ever so slightly peeked his interest. Cora smiled sweetly and waved back. Once a couple feet away, she bows to them. "Good Morning Mr Kaiba, Yugi. Breakfast is ready. I'm off to go tell Serena and Yami." She tells them. Seto nods but doesn't say a word. 

Yami had finished his shower and came out dressed with his hair slightly damp. He looked over to see Serena with his jacket and duel disk. "Oh. Thank you." Smiling softly as he takes his things.
