This whole thing in general is cheating, Ignis. Just us being here is cheating. Doesn't mean you don't deserve it.
Look, best case scenario there's a way to get your sight back that doesn't involve potentially causing issues with the original deal you made and therefor nothing come back on Noctis. It'll be a good thing, you'll get back what you lost and we'll be happy for you.
If something seems wrong at any point to that then we step back. We call it off and nothing is any different than it was yesterday and that's fine too. We're here, Noct's here, we're good. I know that's all I need.
But I think you owe it to yourself to follow this through and at least figure out what your options are. If nothing more comes of it from there, then nothing more comes of it. And whatever you ultimately decide to do with the information you get, I'll have your back.
