我无法明白他这么来去匆匆只是为了看我
In that moment Sal supplies the answer for why Dean came,

这里萨尔告诉了我们为什么狄安回来纽约
"never knew why he had come anyway,"

无法明白他为什么来
and then Sal supplies "except to see me,"

然后一转笔锋说除了来看我
and his own pain and tears are routed through Laura.

他自己的痛苦和眼泪通过劳拉表现出来
It's Laura who cries at Dean's abandonment, while he maintains this composure,

劳拉为抛弃了狄安而哭萨尔却保持着镇静
this masculine composure: "he'll be all right."

男子汉般的镇静一切都会平安无事的
But, the sadness here is surely Sal's.

这里的悲愁无疑是萨尔的

the language of experience that Dean represents is completely exhausted.

狄安所体现的经历语言已经完全耗尽了
This is how Dean talks at the very end:

在最后狄安是这样讲话的
He couldn't talk anymore.

他没说一句话
