Yes I think now is the correct time to bash pari's character because now she is going negative
Till now she was trying to rise her image in the family and I was OK with it, and let's be fair she wasn't disrespectful towards swaragini may be a little rude but not disrespectful
But now she is trying to malign swara's image instead of raising her own image.
So now this is not done. Trying to be a perfect bahu is fine but malignning someone's image to prove that u r perfect is wrong
