What is the subject in 「士郎の理想、英雄となった姿があなたではないのですか。」?


> 士郎の理想、英雄となった姿があなたではないのですか。

I think the subject of なった is 姿, but a friend tells me it's 士郎.

Is it not possible that the sentence means

> The figure that became hero, are not you?

?




As a whole sentence, 「士郎の理想、英雄となった姿」 is the long subject phrase. If I have to
narrow down, 理想 and 姿 are the two parallel subjects.

According to [this Wikipedia
article](http://ja.wikipedia.org/wiki/Fate/stay_night), [this
tweet](https://twitter.com/saber_bot/status/272550240698105856), and [this
page](http://lparchive.org/Fatestay-night/Update%20216/), this question is
made in a special context. Here, the speaker is talking to Archer, who is
supposed to be the reincarnation of Shirou, who wanted to became a hero.
Archer says he and Shirou are two separate beings. But the speaker believes
that the person in front of the speaker, Archer, and Shiro are virtually the
same person.

>   1. あなたが士郎の理想です。  
>  You are the ideal of Shirou.
>   2. 士郎の理想があなたです。("you" emphasized in this form)  
>  The ideal of Shirou is you. ( _or_ It's you that is the ideal of Shirou.)
>   3. 士郎の理想、英雄となった姿があなたです。  
>  The ideal of Shirou, the figure (of Shirou) who became a hero, is you.
>   4. 士郎の理想、英雄となった姿があなたですか。  
>  Is the ideal of Shirou, the figure (of Shirou) who became a hero, you?
>   5. 士郎の理想、英雄となった姿があなたではないのですか。  
>  Isn't the ideal of Shirou, the figure (of Shirou) who became a hero, you?

In the first half of the sentnece, there is a relative clause "英雄となった". And
the subject of the なった is 士郎, as your friend suspected. You can understand it
like 「士郎の理想、(つまり／そして、)士郎が英雄となった姿」 (Here's the article about [GA-NO
conversion](https://japanese.stackexchange.com/questions/12825/), just in case
you don't know that)

AがBとなった姿 = the figure of A who became B; A in the form of B; etc.
