[Joel gives the girl a mildly irritated look. Why has she gotta be so nosy?]

Well, that ain't any of your business, is it?

[He looks away with another vague shake of his head. No, Ellie ain't a little girl, and Ellie more than knows how to handle herself, but... Despite himself, looks back down at the girl.]

Who's lookin' after you, anyways? I know you said you're a-- 'saviour' of the world or somethin', but you look pretty damn young to me.

[Older than Ellie, sure, but still young.]
