The disappointment in Lunafreya's face was clear for Nyx, but it was mostly a look he'd likely have if he didn't maintain the abilities he had from before his death. It was those things, where, when you had something or did something for so long it was incredibly odd being without it.
"Well, it was brought here via magical means." Nyx commented as he looked down at the pin in his hand. "This place is incredibly odd with how it brings things to you. Some of it is just torturous." Shaking his head some Nyx's eyes trailed away. "When this place delivered my apartment from Insomnia, it also gave me a box of Crowe's possessions." Shaking his head, the sadness in his eyes, Nyx still blamed himself for her death - respected and honored her, but he couldn't help but believe there would of been a chance she'd still be alive if he had gone instead.
But then he might have been dead, and never having met Lunafreya.
Snapping his attention to the princess, Nyx smiled a weak smile and nodded. "You accomplished your mission. That honors Crowe enough. It made her death not pointless." Nyx told her, but then froze slightly. She wanted him to put the pin in her hair. "As you wish, princess." Nyx commented keeping his voice cool and his gaze solid. Manuvering himself, he stepped closer so he could part her hair ever so slightly, and used the pin in her hair to secure her hair. Once placed, he took half a step back looking down at her.
