Personally I just don't like problems arising when most obstacles concerning other people were already tackled, I don't mind it dragging on (in a good way) if they continue to just show them being happy and if it constantly revolves around them. Get the brother out of the picture and don't drag the problem.
Tldr, the author can drag the story but don't drag out the problem, it's boring and unenjoyable. Beach chaps, traveling, married life, are some of the themes that can make an already finished story enjoyably drag on.
