I will be honest. As a viewer, I don't feel like watching ATBA's episodes nowadays. I can easily predict what will happen. There are a few potential storylines with this memory loss track and CVs will take the easiest route as they did with the accident truth.
Overall we will see RanVeer longing for one another.
We will see Vikram hurt and depressed (good, Pulkit will get to play a new shade).
Kiara might do something vamp like, she is after all a villain in the show. They won't show her only in positive lime light.
Jai will do something stupid as usual which will bring RanVeer closer.
Not sure how Birju and Champa fit in yet but fillers I am guessing. They won't give neither Birju nor Champa a major role in any of it.
