The goddess Knowledge had once denied that Jason’s mind had been altered when he became an outworlder to better process the kind of trauma he was suffered since. Now, considering his odd equanimity after days of literally soul-scourging torture, he was pretty sure she’d been lying.
I think the keyword is mind. He asked about the mind and I believe she answered 'no' truthfully. She did correct him that it was the soul, rather than the mind. And Jason wasn't ready to hear the answer anyway. That's my perspective at least.
