Although actors Arjun Kapoor and Janhvi Kapoor are step-siblings who share the same father, but different mothers, their relationship is hard to define. Since Janhvi's mother -- the great Sridevi -- died, the estranged siblings have begun bonding. As Arjun said, this is the least he could do.

This Sunday's Koffee With Karan had Arjun playing the protective brother to an obviously vulnerable and painfully young sister. Arjun gave a very emotional account of why he chose to reach out to his father's daughters after their mother died.
