Thorin and Aaron were sitting together. No matter how many times, Thorin asked him Aaron kept denying that he was inside the room even though he was inside the room. The only thing Thorin liked was that the mate bond was healing Edwina faster.
Aaron was thinking about what Edwina was going to say to him after he kissed her. She would definitely kill him, and his death would not be pretty. She was powerful and everyone knew that. The power you don't have control over is the worst kind. And she didn't have control over her power. He saw how she melted the rogue's eyes off. He didn't want that for himself.
His mind went back to how he came in and spent time with her and then the tragedy struck. Thorin wanted to come in. He was not allowed but Aaron jumped on the windowsill again and Gadburg spotted him. Thank Moon Goddess, he didn't recognise him, he just saw a dark figure lurking outside.
