Stone Circle it's because he was lying in front of the heater

It was not long before her brother arrived, looking and smelling a little worse for wear. But he was alive, and as far as she was concerned, the rest could be remedied. She danced in place and then set off to meet him, figuring a few feet further wouldn't hurt anything. But then he greeted her, and she faltered at the tone of his voice, and looked a little closer at the expression on his face.

"I'm sorry I lost track of you," she said, mistaking his panic for worry about his son and anger at her for losing him. "But I know where Valiant is, and I'm going to go get him and bring him here. He's safe, okay? With Sunspot. And I just left him there so I could keep looking for you and Dawn."
