We have to be standing in

我们必须在正确的时间
exactly the right spot at exactly the right time.

站在正确的位置
Then, and only then, can the door be opened.

只有这样山门才能打开
So this is your purpose, to enter the mountain?

那么你的目的就是进入孤山了
What of it?

是又怎样
There are some who would not deem it wise.

这未必是个明智的举动
What do you mean?

什么意思
You are not the only guardian to stand watch over Middle-earth.

可不是只有你在守望着中土
Not with your companions?

没跟同伴在一起吗
No, I shan't be missed.

没有有我没我都行
The truth is that most of them don't think I should be on this journey.

其实他们都觉得我根本就不该来
Indeed.

是啊
