Fate Stay Night - UBW 7

As someone who has only watched the anime version of the Fate series, this episode has covered alot of grounds that the UBW movie didn’t.

The main comparisons between Deen’s version and Ufotable version is

• There was dialogue between Shirou and Archer exchanging their opinion about their ideals and having a conflict about it.

• Archer has already started to cut down Shirou before he reaches the Illya arc.

• Archer overpowering Caster

• Assassin didn’t die instantly and helped Saber & Shirou escape from Archer

What I don’t get is why does Archer go to the extent of saving Shirou so many times and yet at the end wishes to kill him? He could have easily slain him at the temple multiple times instead of saving him to try and kill him.

How does Rin not detect her servant using her mana so excessively? Is Rin a deep sleeper?
