The Mortal

Something's different about this mortal than the rest of the 7+billion of them, so what is it? What makes Lilliana (Lily) Clark so special to Loki? When her life was in danger, he came down and saved her, then brought her up to Asgard. Now she's in even more danger and he feels the need to protect her. Why? Why did he even save her in the first place? "What makes her so special" is the question he keeps asking himself, but he can't figure it out.
