1,if I were you, after I've seen it, I'd go through all the options with someone.
2,if I were you, after I had seen it, I'd go through all the options with someone.
在表示未来的句子中,从句里完成时态表示未来终结类意义。比如 after I have seen it, I will go through all the options with someone.
文章背景是在给人建议,用了虚拟语气, after从句是也需要时态提前,变成after I had seen it吗?
