Yash feels guilty about Arpita's death because he felt helpless at not being able to do anything to stop the accident that took Arpita's life. He needs to come out of his grief and help his kids before it is too late and they carry this trauma into adulthood. I am mad at all the adults in Scindhia family for not helping Palak since Arpita's death. My god! The little girl instead of enjoying her childhood, is traumatized, hurt, weighed down with a ton of guilt thinking her mom died because of her birthday. Aarti you have my full support, go right ahead and plan Palak's B'day. You can make a difference in her life. I wish you lots of luck!!!!!!!
