from baidu:
"段正淳的风流孽债实是情节发展的关键所在,许多意义非常重大的线索,都要从大理段二身上引出来。段正淳本人并没什么出众之处,但对此书却非常重要。段正淳的爱情是分段忠实式,并非全然勾三搭四。看他见了刀白凤,眼中全然是凤凰儿;见了秦红棉,又只知道世间上有一个红棉;见了甘宝宝,一心一意又只想着对宝宝好。这种精确划分的分段忠实的爱情,大有精彩之处。"
I still prefer the 2nd edition that 段譽 and 王語嫣 ended up together. I do think it's reasonable for girl to change like that... (i mean 王語嫣 turn away her passion from her cousin to 段譽).
And 段譽 remains faithful and end up together is just the perfect 童話式 ending in girl's mind la..haha
I guess the 3rd edition is more for "guys perspective"...when they 得到手, then passion started to die down...haha
