就在你开始打盹的时候，你才发现已经是凌晨两点了。

Just as you're about to nod off, you realize it's past 2:00 in the morning.

而且通常当“零星”降落时，你才发现，它们其实是飞机。

More often than not, they turn out to be airplanes when they land.

居高临下，你才发现它那些没有窗户的堡垒，崩塌的围墙，遍布碎石的庭院有多么僵直、多么空洞。

You could see how stark and empty it was from up here; windowless keeps, crumbling walls, courtyards choked with broken stone.
