Roxas hesitates to follow Axel. He doesn't know Saix very well, and he doesn't like him, but this is maybe the first time he's been able to see him not just as some jerk but as a person. It's not just that he's in Axel's body, either. They're still Saix's thoughts, and the feelings he'd have if he could feel.

"The Organization wasn't doing anything good to us. And I know when I chose to leave- I did it wrong." He left Axel behind. He glances towards the portal. He can't really speak for what Axel feels, so he isn't sure what else to say. With one last uncomfortable glance at Saix, he follows his friend into the portal.
