I am still supporting truth telling/helping Abhi with memory as the best policy. Taking Taaliyah to jail is the parallel best policy.
Given the team does nothing of the above, I wonder why they are trying to make Abhi realize he loves Pragya.
Even if Abhi realized his love for Pragya, they won't tell him the truth. Then the situation will be like, Abhi will be sad that he loves Pragya but has to marry Tannu. I do not see him letting Tannu's mom die while he breaks up with Tannu. Nor can he easily back off from marrying Tannu given the molestation defame issue.
So, if Abhi realized his love for Pragya, it's more pain and frustration for him and even for Pragya. So what's the point in going to this almost suicidal situations to make him feel love for Pragya?
And then, him realizing his love for Pragya when Purab-Pragya are a couple, is even harder.
In that situation, why can't Pragya tell Abhi that SHE LOVES ABHI? She doesn't have to tell the past truth but just the present situation where she can tell she always admired RS Abhi and now seeing real Abhi, she is really in love. She can also say her love is one sided and she doesn't expect him to love her back.. but she needed to get it out of her system.
So that leaves the ball in Abhi's court. He will find a new meaning to his connection with Pragya. He will at least recognize that bond to be more than secretary/friend- boss/friend bond. He will realize his feelings are similar to hers. This is also repeating history.. but we all know Abhi did start to think in terms of "love" earlier in the soap after she confessed.
This way also, Abhi may not be able to kick Tannu out of his life without knowing the truth. But if he recognizes and admits his love for Pragya and knows that Pragya loves him too, it just makes it easier for him to share all his heart with her and even Pragya can start to remind the past and tell him truths!!
