Ok so, I have a question. If someone who remembered Artoria were to tell Henry about Artoria, could he use the Silver Eyes to bring her back? Not just a clone or something, but actually her?

To explain: the power that undid Artoria is far beyond anything/anyone else in the whole multiverse. She was quite well warned to not do it and still she did so... you know the rest.

But, don't worry, like I said the next battle will rub quite a lot of salt on this wound of the Demon's collective heart (the irony of this isn't missed). Maybe, in the future it can lead to a chance of getting her back but this is not you should be thinking about now.
