Well, he wasn't going to find Shinon by listening for a sound - he just had to cut through areas until he could catch sight of the archer.

And - aha! Catch sight he did! He felt it was best to stay hidden in the bushes for now, however - for some reason he decided that he would observe this human for a while.

... A minute passed and he had had enough. He came out of the bushes, and began walking slowly towards the man, clearing his throat and beginning to speak. "You are Shinon, are you not?" he said in his usual gruff voice.
