All the characters have to do is support WHAT IS RIGHT in a particular situation and everyone would be fine. Gayathri just needs to support the TRUTH.
Had Gayathri not been biased toward Akash despite knowing he lost the cricket game, Yash/Radha wouldn't have been upset. Had she not been biased toward Ishita, Paridhi would not have been upset about the necklace. Had Gayathri given her blessings to all the kids equally, there would be no problem. Something like giving her blessings shouldn't be something that is favored towards a certain person. If she's choosy about that, her blessings are worthless and impure and Yash shouldn't even seek them.
If today Gayathri supports Akash over the bar scene, it'll show how corrupt this woman is. I don't think I'll have any respect for her after that simply b/c a greater thing was at stake: Aarthi's safety/honor. The reason behind it? Akash.
Yes, SP made mistakes: 1. his betrayal 30 years ago 2. messing with Akash's DNA papers 3. still not having said sorry to Gayathri and family. However, he's still giving Yash the same affection as he did before knowing he is illegitimate. (of course, it can be argued that whether or not Yash is illegitmate, he is still SP's blood, just not Gayathris and so it wouldn't affect SP's love as much).
Point being, Yash has been raised as the favorite of 3 brothers for 30 years. Just in a few days Gayathri forgot all about that and is supporting Akash in everything regardless of whether or not Akash is appropriate in his behavior.
Of course in the future Yash/Aarthi will forgive Gayathri, but I want her to have to struggle for that and truly understand how terrible and unfair she is being. It isn't enough that she TELLS Yash that she still loves him the same. She has to prove it through her ACTIONS. I want her to repent severely for how unfairly she treated the son who actually cares about his family and stands up for what is RIGHT, not what makes the people feel happy despite their ill doings.
