Yep, Lea totally jumped at the sound of the unfamiliar voice. And the fact that it was a voice, not a growl or the telltale sound- and smell- of darkness rising and taking shape was the only reason he didn't summon his Keyblade as he spun to face her. He relaxed a bit letting out a breath in a bit of a sigh when he saw that the voice belonged to a relatively ordinary-looking teenage girl; about the same age as Sora and Kairi, maybe a little older.

"Man, you walk really quietly, you know that?", he said. "Anyway, thanks; I'll take all the help I can get. Name's Lea; got it memorized? How about you?"
