What is the difference between Maha episode & promo...???

Hello everyone I saw today's apparently the Maha Episode....and I wonder what exactly they wanted to show....interms of PREETA & KARAN they have only showed exactly the same clipping they showed in the promo nothing more than that.....I mean really!! how much makers will play with us...by such silly antics....😡🤬🤬 those who have not seen the episode good for you....go and watch the promo that would be enough...
