As Roxas had been observing his surroundings and trying to piece together just what had happened to bring him back to such a familiar place, a sort-of familiar voice happens to echo out to him. While familiar, he couldn't place it and so he reacted the same way he would've to anything he wasn't sure about: whipping about to face it and drawing his keyblade in the same heartbeat.

Yet as his view settled on the source of the voice, he found himself more confused than threatened. Unwilling to let his guard down, he still advanced toward the source of the voice. He knew this face, this voice. Just he couldn't fathom why he'd run into an Organization member -let alone one that had long since been vanquished in this place of anywhere else.

"You're... Zexion, wasn't it?" Roxas stops a little more than arm's length away, weapon in hand, but not ready to strike. While there was recognition, there was the fact that he'd been told the Castle Oblivion team were traitors, so then that meant that they might not have any particular attachment toward Xemnas either. But then, that might not make them his allies either. Also confusing was the fact that Zexion wasn't in an Organization cloak, but lab attire.

It was really a pain when he couldn't tell who he could trust.
