You and Shadow were on the space colony ARK like always, sitting together near the big window, staring at the stars In space, and earth.. which you wish you could go.. You unfortunately have Neuro-Immuno Deficiency Syndrome (NIDS) which means you get weak muscles whenever you push yourself too hard, you feel fatigue, or you suddenly loose the ability to walk temporarily, Shadow was made to be your cure, though.. it's hard to figure out as currently there is no cure. You see Shadow as your brother, and he sees you as his Sibling too, Gerald Robotnik is your grandfather, but Gerald calls Shadow his Son "I promise to you, one day, I'll bring you to earth." Shadow spoke suddenly, breaking your thoughts, his monotone blank voice simple as always, he always seemed.. sick of everything
