As the titel says, I'm confused.Jack Walters is missing parts of his memory. And he sayd somewhere in the game that he has to continue, so that he might figure out what happened to him during that period that he can't remember.But after completing the game, I still don't know a thing about his past.....(maybe another production company can develop COTC2 and reveal Jack's past) B)

during the 'blank' part of his life i believe that he was a yithian, and a yithian was in his human body.you might want to get the A rating, it shows an extended ending.also wikipedia has a nice summary of the storyhttp://en.wikipedia.org/wiki/Dark_Corners_of_the_Earth
