May be the single strangest example of father-son time I've ever seen.

Son from future is brought back by a sick, twisted Magic to a point in time where said son isn't even the father's son? Sure.

I want to see this elaborated on.

Same here. Especially curious on how Kiritsugu might try to deal with being idolized much less his reaction to learning that Shirou is his future son.

Also does anyone know if the picture with Saber grabbing Berserker's helmet while Shirou holds a dish is a part of this?

Shut up and take my money!
