Legolas have been so busy taking care of the Orc that was he currently advancing, he didn't notice the other Orc that was about to go for his back. He had managed to catch sight of the girl before him, and her words didn't go unheard. With a thrown sword coming directly towards him, he instinctively ducked, letting the blade miss its mark, and hit the Orc that was behind him. Watching the creature fall dead, his mouth gaped slightly in surprise, before turning back to see Yavanna again. 

There was a thought about her; her bright light, knowledge of spells, combined with her conscience views, the girl was something special. These were traits that he may not never see again; the last time being with his mother. Could she be [i]that[/i] special? His gaze was caught with hers, just as he realized that not only did she defend him from Thorin, but also saved his life. She must be that special.
