Best of Luck Nikki

Dolly moves her study date with a cute boy, Ritesh, from the library to home because she has to help Avatar take care of Nikki while Himani returns to work. Avatar injures himself falling down the stairs, so Rohan must take him to the hospital where Himani works, leaving Dolly to watch Nikki.

Dolly encourages her parents to go out while the kids take care of the baby. Rohan flirts with a cute girl, Punam (Shivani Joshi), while minding Nikki--and accidentally brings the wrong baby home. After a failed search, the kids go to the restaurant to tell their parents--and find Nikki sitting with the cute girl's family a few tables over.

Dolly discovers that she has an Narendra Tauji (English: uncle her father doesn't speak of); she visits him and they go to a cricket game, where she realizes why they never got along. Sunny and Rohan try to make money modeling Nikki for a baby-store ad.

Himani pressures Dolly to be in the school play, "Dinku the Donkey", and she gets the part despite trying to blow the audition; a baby basketball match is set between Popi's nephew and Nikki.

Roli Aunty agrees to bring her dog inside if Avatar cuts down a tree, but Dolly and Rohan stage a sit-in to save their childhood tree-house. Avatar wages war against his disobedient kids while Himani gives them her support.

Dolly is annoyed that her best friend Pam has become “texting buddies” with Himani, so she attempts to bond with Pam’s boring mother. Sunny and Rohan mistakenly believe that Roli aunty has killed her husband, so they go to Roli aunty's house to investigate.
