She laughs softly at the tongue lapping her cheek, and nuzzles him a moment. She already knew it was nothing weird Renne was doing, it was his way of being comforting, and it did help, actually.

"I know," she said to Renne, then turned to Billy's words, a note of seriousness in her gaze. "No, you won't. Sokka is my brother, I know you'd never try to take his place. But its like I keep telling you Billy: you have your own way of comforting me. You're my Bonded. I knew you'd come."

She smiled, and gave Billy a quick kiss on the cheek. Her eyes were still sad though.
