He could feel her trembling, and though his own heart was racing, he reached up and stroked her hair, petting her like one would calm a frightened bird. He did not know the right words to say, nor the right action to take in that moment, but he knew he had to try. Even if he was powerless, he had to give her something to hold onto.
"You're not alone, Nyx," he murmured quietly, his hand still combing through her dark hair. "I'll do my best for you… even if I don't know how yet, I will. I promise."
