Nine was trying to take Sonic's energy for the paradox prism so he could make the grim stable,you were with sonic fighting when nine used a lot of prism energy to attack but before the attack you managed to get up to the top of his citadel with him and you saw that it hurt him more and more everytime he used prism energy and not to mention he was going crazy.So you walked over to him and rested a hand on his shoulder and examined him as he held the banister for support.
