Frustration! (With Spoiler)

It is so frustrating to see how in the coming days Yuvraaj will be very angry with Suhani for her supposedly mixing up Pratimas medicine but what i dont understand is why doesn't Pratima just stand up against Dadi or even tell Yuvraaj about Dadi and her two brainless side kicks' plans?! Also i hate how in Indian shows they show the son always taking his either evil mothers or grandmothers side over his wife! They seem so blind to things around them! Plus how can Yuvraaj doubt Suhani?! I know he doesn't love her but from what he knows of her character he should be well aware that she would never intentionally hurt anyone especially not Pratima! When Suhani does find out the truth (Whenever that will be as it seems to drag) i hope she stands up for herself very confidently and with her self respect! There is only so much a person can take however optimistic they may be!
