Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Your sister-in-law should maintain cordial relations with one and all. The laws of purdah should be observed with those she is supposed to. This is the requirement of Shariah. Situations which can cause unnecessary tensions and suspicions should be avoided. Your sister-in-law should either go with her husband or your mother to visit the relatives. Unnecessary chit-chat and gossip and futile talk should be discouraged. The family should strive in working to make a harmonious climate and for that they should act accordingly with due diligence and tact. Your sister-in-law should be advised by the elders of the house. 
And Allah Ta’āla Knows Best
