I don't get it, in the 1st book, it says that Tobias reads Jake's mind through thought-speak, but it's never mentioned again, as far as I remember, throughout the entire series. Did K.A. just change her mind about that? Cos a lot of peops do that when writing, leaving plot-holes...etc... they'll mention something then maybe in another book say 'no, we can't do that' or something.
