I think the current storyline will get a whole new dimension depending on Riddhima's reaction. If there is nothing from her then two parallel tracks will continue without AR. HOWEVER, Armaan and Shilpa's story can't move forward without Riddhima's interference. Shilpa needs to know about her and Armaan has to face her everyday.
Its hard to imagine Riddhima NOT reacting to them two and to be honest its actually a waste of a potentially INTERESTING storyline.
AND AND AND...it will give Jenni more to do than just lecture every single person she comes across on-screen. Man give her something more to do instead of wasting her talent!! 😕
