The king snores, perhaps?

莫非国王打鼾
Or simply prefers solitude?

或是喜欢独寝
Pressures of command, no doubt.

想必是国事操劳
Four kings vying for the throne.

四王角逐嘛
I am not tutored in warfare,

我没学过兵法
but basic arithmetic favors the side with the greater numbers.

可只要懂算术就知道人多容易赢
If war were arithmetic, the mathematicians would rule the world.

靠算术能打仗数学家早统治世界了
I did notice your brother entering His Grace's tent just now.

我注意到您哥哥刚才进了陛下的帐篷
The place of a kingsguard is by the king's side.

护卫的位置当在国王身边
And on the night of the your wedding,

那你们的新婚之夜
who was by the king's side then?

又是谁陪在国王身边呢
You seem quite interested in our marriage.

你好像对我们的婚姻很感兴趣
