Thanks,
1. In your sentence, 俺が見たいのは、おまえがへや着を着たままの姿だ, is 俺が見たいの the subject of だ?
2. If it is, then おまえ is not the subject of any verb, despite being marked by が, right?
3. In the sentence カーテンをひっぱがして、おまえがへや着を着たままの姿でいるところを、見てやるぞ, what is the subject of でいる? I was thinking it was おまえ (making the grammar somewhat different from your example), but now I'm not sure.
Thank you for your help with this. There are aspects of the grammar which I do not understand and I would like to get straight in my head.
