He walked towards the pod after having talked with DiZ's hologram. DiZ had almost seemed like there had been a choice, but... he really didn't have one. He knew that he was trapped in this mansion.
He thought about a lot of the things that Namine had told him, and that Axel had told him. In a way, Sora was his chance at another life. She'd said he wouldn't disappear. He'd said to wait for him there. DiZ wanted Sora to reawaken from Namine's spell... to save the worlds once more, this time from the very Organization he, Roxas, had betrayed.
The pod opened, its petal-like doors blooming to reveal Sora sleeping peacefully inside. Roxas wondered what if it was something like a womb, if this awakening would be akin to a rebirth of sorts.
DiZ'd said that Sora needed some of Roxas' hatred and anger, and Roxas wondered if Sora's personality would be changed when they merged back into one, despite his claims that his heart was his. He stepped closer to the curiously shaped pod.
"Sora, you're lucky... looks like my summer vacation is... over..." Roxas sighed, looking up at the sleeping form, somehow suspended in place. He climbed the doors of the pod, and wondered how exactly he was to complete what he knew needed to be done. Leaning forward, he placed a light kiss on Sora's pouty lips. His eyes fluttered closed, and he felt a tingling sensation begin. He pulled back slightly, wondering if he was doing this right.
Suddenly, he felt like he was diving head first into cool water. His physical body faded away in the light of Sora's aura, and he noticed that he looked like a ghost. He stepped up to Sora, lined himself up to his exact pose, and walked backwards into the brunet. Everything went black.
