Yeah... i was just wondering:
<span style='color:#D6DBE0'> In the later thirties when they&#39;re having the preliminaries, and Orochimaru is just standing there watching, and then later he pops up behind Kakashi and he knows right away that it&#39;s him.</span>

<span style='color:gray'>why could nobody tell it was him before? with all the byakuugans and sharingans i would have thought someone could see him, or maybe see that he wasn&#39;t part of any group and didn&#39;t take the test and nobody knew who he was and he was so obviously evil...</span>
