An 11 year old named Kaustub moves in near the Singhs, and he's the opposite of Sunny (polite, thoughtful, eloquent). He develops a huge crush on Dolly, and convinces her to spend time with him, or else he won't go away. He takes her on a "date" for ice cream- at his cousin's 6th birthday party. Meanwhile, Dolly finds out that Ritesh is spending time someone new. Caught off guard, she lies and says she too is has someone - a boy named Kaustub. Of course, she then runs into Ritesh and his new girl Sheena while out with the real Kaustub at the ice cream parlor. Rohan and Popi decide to add a 3rd member to their band, but when Nikki gets him sick, Avtaar steps in to perform - and ends up taking it overboard.
