[Of course, the one day he sleeps in is the day that he starts to have trouble. The nightmares start when the Core begins to have trouble and it's not long, of course, before he awakens. He's recognized the building darkness in his heart since Mickey, Sora, and Kairi's disappearances, but something feels inherently off today. Something whispers at the edges of his subconscious as he gets up and stumbles out into the living room. The sun's blinding as it comes in through the windows and he stares out into the city without any coherent thought to his name for several moments.
It's when he suddenly hears someone else's thoughts that he starts to suddenly panic. It's not even Ansem he hears - not the one who's walking around the city, anyway - but the one imprinted on his heart, the one whose darkness keeps leeching to him. He hasn't heard him in months.]
[The NV hits the floor with a clatter as Riku stumbles back against the wall, holding his head. The splitting headache makes him dizzy, nauseous; he reaches out with a hand to close the blinds. He slides down the wall.]
Stop it. Stop it! I got rid of you. You don't exist anymore!
[No one can be heard on the other side of the NV. Riku's too panicked to just think; his thoughts aren't his own any longer.]
Shut up! Get out of me. I'm not your puppet any longer! I don't bend to your darkness!
[Another wave of darkness clutches at his heart and he hisses in pain, striking out with his foot. He kicks the NV into the wall and it times out.]
