First of all, Archer's life experience and fate are different.

Secondly, Naisu is in Q &；; As mentioned in A, this is because Archer "probably" saw something similar before he died.

Q: At the end of Sakura Road, Shiro was saved because there was only magic left in Tohsaka Rin's necklace. Then, judging from the gap between the people who came back from Archer and Shiro's residual magical power, Tohsaka Rin seems to have predicted it in advance. Sure enough, Shiro of the Sakura Route will eventually become an archer? Or which route will not be haunted?

A: No route will become, and any route is possible. Let's talk about it first Although it is almost infinitely close to zero.

Q: Archer seems to know the existence of the same species as Angra Mainyu in advance in the cherry blossom route. Does he have any experience in fighting such enemies at other times?

A: Before you died, you met something similar, and then you chickened out without hesitation. In addition, after reaching the seat of the spirit, you will become aware of what the object of suppression is.

Let me comment again. Is Sue's answer to the first question, is obviously left a posterior approach for yourself. In case he wants to create again, he can make it up without hitting himself in the mouth.

In fact, if you sort out the movements of Shiro and archers in the three lines, you will feel that the life experienced by Yinglingwei Palace will definitely not be Shiro's life in these three lines.
