Do it before it affects her ability

" I only know one thing I saw my son in the same room as her!" Madam Sun pointed at Yu Dong as if she was accusing her of dire consequences. " My son might be a fool but in the end, he is a mer, does the Yu family think that they can just play with him and then leave him? There is no way! Even if I have to go to the Yamen and beat the drums and gongs, we will see who will be losing!" 

Madam Sun pretended to speak up for her son's reputation but in truth, she was threatening the Yu family. With Yu Dong being the current head of the village if her reputation was sullied then it would surely be not a good thing for either Yu Dong or the Yu family! 

" You old hag!" Yu Tong who took Yu Mai from Ye Liu's arms glared at Madam Sun. " My nephew has told me everything! You deliberately locked my sister up and then pushed your son inside. With my sister's reputation and status what kind of mer she cannot get!"
