Zack tilts his head questioningly at that. He didn't expect to hear it, certainly not from Sephiroth still so young in his career, though the words themselves are similar to what he'd heard before. Back during the desertion, after losing Angeal and Genesis, he'd all but threatened to leave Shinra himself, depending on the results of their investigation. Sephiroth was a loyal SOLDIER for many years, but he was not without his limits.

"What happened?" he asks, his voice gentler than before.
