So Ishqi manages to look for another valid reason to justify why she left the mandap considering she can't bring Sonu in the picture. She finds out that her juice was spiked based on Mayank's say and brings the waiter as a witness. Ishqi shouldn't have to justify herself for not wanting to go ahead with a wedding. But I'm glad to see Ishqi trying to do something about the situation; somehow trying to trap Mayank in something atleast instead of passively just getting blamed for everything.
And Ahaan seems to have cooled down a bit and is willing to consider if there is some other reason. But looks like Mayank will do something and turn the tables on Ishqi causing Ahaan's anger to continue. The waiter might end up saying something like Ishqi has forced him to blame Mayank. And the police arrest and the drama would happen.
