@Hitsuji Mamoru to be specific Its the "Mind of Steel" ending. it was the first mention of the term in the Fate verse. Long story short its an ending where Shirou promises to protect Sakura no matter what but when he finds out shes a threat to the world allows her to die instead saying hed kill her himself if someone else didn't. Kotomine is impressed and comments that now Shirou really is his fathers son and is guaranteed to win the war because he will kill all the others masters including Rin and Illya with no remorse, just like Kiri would have.

I believe the metaphor was something like he locked his glass heart away and became cold unfeeling steel that will get the job done no matter what, its been a while i'll need to reread it to be sure but it was something like that. its one of the only endings where Nasu confirmed Shirou did win the war even though its not a "main" ending and yeah it implied that shirou is the one who became Emiya alter.
