I distinctly remember being able to talk to Thancred between quests and him saying his eyepatch was for fashion, not injury. Cus I remember being annoyed with him for letting me think he'd lost an eye for as long as he did, while also being exasperated b/c *of course* he did, its Thancred. I remember saying to myself "...Yeah, nevermind, he's fine."

Unfortunately I do NOT remember when I talked to him. It was not in a cutscene, it was not a result of a dialogue choice box. It was just a *right click on character, character talks* moment, which I was getting a lot of in Stormblood cus I made sure to click on every scion that didn't have a marker above them before I advanced to the next quest step. This exchange might even have been in the pre-4.0 patches.
