In the old mansion at Twilight Town at the beginning of KH2, there was a table in the library that had a drawing you(roxas) had to finish. It had three circles, one with the heartless sign, one with the nobody sign, and the third one blank. Later, when roxas fills it in after talking with namine, it doesn't show what exactly he drew. Could it have been the symbol of a new threat that might appear in KH3, or something else? I want to know what you guys think.
