Since witnessing the indisputable evidence of Axel's arrival, Zexion had considered the possibility of others coming through. Xemnas, Keyblade Bearers, Maleficent and more besides. It was highly likely that at least some of the non-Nobodies amongst their collective number had associates as well. Even so, there was no way of knowing for sure which of the two possible scenarios had taken place to bring Axel to Spira, so he hadn't driven himself in endless circles thinking about which was more likely or the risks associated with them.

"Without asking Axel himself, I'm sure we'll never know," said Zexion, his voice made dull with unhappiness. "There was no love lost between him and the rest of us when he left The Organisation, we all know that. Even without hearts, we found his actions deplorable. Furthermore, the last I had heard, he and Saix were not on the best of terms."

Axel had betrayed them all, but Saix had every reason to take it personally. While his lack of heart meant that didn't, in fact, take it as badly as he could have at the time, Zexion didn't doubt that it had niggled at him since his return to a complete state. Isa's childhood bond with Lea would have been all too easily remembered once he became whole again and there was a very real chance that the betrayal he'd suffered at the hands of his Nobody would have felt all the worse for it. That said...

"Saix was more than happy for Axel to shoulder all of the blame for orchestrating Castle Oblivion's failure," he pointed out, making sure to keep his expression entirely neutral. "Saix was behind it all. Axel had been acting on Saix's instruction. None of us knew that until Saix accidentally revealed that he knew more than he should about what happened there. That they should team up again seems strange in light of that. Nevertheless, they have..."

At the same time as trying to rationalise that, he struggled to imagine Xigbar taking him into The Order with a clean slate and no questions asked.
