In some weird Force shenanigan thing while most of the clones (except for Cody—he's with the Jedi Generals when this happens) are in the Republic Venator's commons barracks room, most of the clones get turned physically and mentally accurate to the chronological age that they are (12-14). When the Jedi and Cody return to the barracks room, they're surprised to see a bunch of young clone cadets where the clones originally are. Shenanigans ensue?
