Why this twist?

Out of all of the twists in the world, why did ekta bring this twist!

i dont like it at all she had so many choices of twists like- angad or kripa having "cancer"9but later they find out they dont), one looses their memory, or just anything! but this twist is horrible!

it brings that dumb prithvi into their lives again! no man would want their wife to get pregnant with someone's elses child! uhh! Ekta pisses me off!
