Informed by a lengthy flashback, we are made aware that Hrithik Roshan, playing Rohit leaves to work for a scientist wearing a very poorly cut, distractingly long suit.
Many years later, when Hrithik plays Rohit's son Krishna, he leaves for Singapore wearing the exact same suit.
Clearly Rohit's mom, played by Rekha, liked bargain sales.
Also, she invested in her appearance quite well, considering Rohit, at the end of the film, looks much older than his mom.
