The one thing to remember about these mahanta types is that they think they are prosecutor, jury and the judge. what they believe is right and others who might not be wrong - but not following their strict guidelines - end up bearing the brunt and having to sort the madness created by the mahaan people. It is not different here.
Swara is so focused on getting Ragini redeemed because she feels Ragini has changed, that it doesnt matter to her that she rakes up the old past of someone who has been her sole support in all this. She has forgotten that Sanskar apologised first and started working on his redemption already and even then he was always doubted and taunted and it took him eons to truly have forgiveness from his family. Ragini on the other hand has only now started saying yes she wants to change but is yet to do anything conclusively. But in Swara's eye she has been redeemed and her point has to be proven to the rest of the family and they are meant to follow her lead by hook or crook (like she plans to make laksh fall for Ragini).
So in all this Sanskar is taken for granted and used again. Yes he has given her the right, but even if he hadnt Swara would have still gone ahead with it because she can only see Ragini right now.
Insanity runs in Garodia family and quick reactions without thinking in MM house. Sanskar was the first one who was struck with it. He didnt investigate the death of Kavita and went on wrong revenge track and he then pushed Ragini who was already at the edge of the cliff over, in this plot.
then came Ragini who went off track helped by Dadi, Shekhar's this is your husband jaap, Lucky's on-again off again engagements and then Swara and Shomi being blind to her pain (though they are supposed to know everything apparently). Had they thought this through, all Ragini needed to do was let Swara know she loved Laksha and mahaan devi Swara would have forced Lucky long back to fall for Ragini (the way she is going) and backed off. Sanskar would have had his revenge as well...instead of all the stupid plots.
Now it is Laksh and Swara turn to turn dumb, insane and rash. Laksh with his on again and off again love/trust/wanting for Swara. Swara on the other hand lost her sanity long back when she along with Shomi thought that they are going to reveal Ragini's truth without impacting Laksh and her relation! hello he was dying to get out of the relation with her and anyone with blind eyes would have been able to see that with all the drama that was going on. Then after the reveal, Swara feels that Lucky knowing was enough - what happened to maa baba then? They were going to get together without the reveal as long as Lucky knew? Then comes this new drama of making Lucky fall for Ragini. To top it, if you know Lucky is being to obsessive, why are you giving into the obsession? why not take Sanskar along to put some sense into his brother or better yet let DP know? But here is where mahanta devi feels she can handle everything on her own and will fall on her face and Sanskar will need to bail her out. He as is knows not to trust Ragini now so when swara said she trusts her, I am sure Sanky's expression was more on the lines of - okay so i now need to protect her from lucky and Ragini again!
Today the only somewhat sane person in all of this is Sanskar. Somewhat sane because no fully sane person would have stuck it out with her in real life...thank god for Swara this is a serial. He has also given up the MM trait of rash reaction - which would have been good right now for his own sanity. but bottom line is Swara, Laksh and Ragini are messing up a lot of relationships to save one that they are obsessed with .
