Roxas followed him out more slowly. He couldn't feel exactly where the other end of the portal had opened up, but that was enough to tell him it wouldn't be close by. Following Rin's gaze, he caught sight of Vanitas on the far building, and just looked up at him frowning for a moment.

He could have followed. He could have opened a portal to that roof and tried to continue the fight. But it wasn't a fight he'd gone looking for, nor one he really wanted.

Instead he just let Oblivion vanish and turned to the boy with the tail. "You okay?" ...he didn't exactly look it, but Roxas probably didn't either.
