when it can reasonably be fixed then just do it.

Because I mean if it was actually possible you'd think people would know
And Mike going "maybe" at a yes/no question isn't implications, it's WOLOLOLO because nasu felt like it. Which he's done many times. So unless he actually "yeah" at something I'm not holding my breath.
Anyway, Ilya is like a fine dessert, you appreciate her as glorious and great and amazing for a short time and then she's gone, but you truly appreciate the moments you spent on her. And though you wish it could have lasted longer, you feel perfectly satisfied with what you got.
Meanwhile the heroines are like bags of chips that you can just keep eating forever that never truly satisfy you because unlike with Ilya where the game is trying to sell her to Shirou as a little sister and in a non-sexual role, the game tries to make you lust after the heroines with sex scenes and SABER'S MUSCLES AAAAAAAAAAAAAAAAAH. And because you can't stick your dick in the heroines it will never be as 100% satisfying as truly getting to know the pure little snow angel who protected her little brother.
Basically old Ilya is pointless, long living Ilya is nothing but a shallow illusion, but FSN Ilya who got to know her brother is nothing short of perfection and I would never change that.
