Can you understand that he needs to? If he doesn't comply, he won't be able to complete the quest.
Do you perhaps lack reading comprehension? I did say that I understand that the system gave him a mission. The issue is how easily he accepted the order from his brother instead of negotiating and getting something from him. The brother is basically using him, he should've done the same specially considering this brother acted all arrogant last time they saw each other.
So his brother is simply going to order him around just because he wants to? I get the system triggered a mission, but come on... is very unrealistic that the older brother that doesn't like him now comes and wants to use him for his advantage and he simply agree?
