So I just watched the episode and I am dying because this show is no less then any Ekta show. Mahi's return on this way is definitely to double cross Luthra and take revenge for the betrayal and implicating Twinkle but it's not a changed Mahi. Mahi has been this manipulative and strong since the beginning when she threatened suicide over taking her Yuvraj away from her. She also stood up to everyone including her father in beginning just to to live the life as she wanted.
But man, the death of every last shred of logic from this show is way too much for me to handle. I don't know wether to laugh or not.
