Loki watched the girl and he looked at Diaval who was on a branch above him. "I'm not afraid of the dark, Beasty", he lightly snapped at the girl before turning his head away to turn away from her. He lightly huffed to himself as he closed his eyes and remembered his mother's words. 

[i]You must help her grow. Get close in personal. Show her that she has nothing to fear. I'm counting on you, my son[/i]

He made a quiet sob as he remembered his mother's spirit from before. He promised to not dissapoint her and he would be a king and a protector her. That means he must protect the girl.
