They have planned a track involving Anandi, Nidhi and her family 2 months ago.
According to TB Article...
"A new family will be introduced in the upcoming track of the show in which Malini Kapoor has been roped in for a cameo role. Malini has been roped in to play the character of Vasundhara who belongs to a very rich family. Vasundhara is not in good terms with her husband and the fights happening between Vasundhara and her husband has made their daughter Nidhi a depressed child. She wants to leave the house and join Anandi's (Toral Rasputra) school. Vasundhara is very much concerned to send Nidhi in her school as she finds her school an uncomfortable place for her daughter to adjust. The forthcoming track of the show will unravel as how Anandi will help Nidhi in overcoming depression and rise as a better person. She also convinces Vasundhara and her husband as how their fight is affecting their daughter."
"As the story will move forward, Vasundhara's son will make an entry to the show who will be seen coming back home after studying abroad. He won't like his sister studying in Anandi's school, so he will visit her school to get her sister back and he will start liking Anandi."
I think the part in Blue is not yet covered. Did they exclude this part ?
