This is what would have happened -i think it would be a fairly logical explanation -
Last week, robbie witnessed all the chamatkars of Kasturi's fire proof saree
He was very taken in with the material and he stood there amazed and shocked to see the 8th wonder of this world (ie kasturi running that mile without becoming an urn of ash herself) it shocked him so much that he stood there immobile (for a few min) without jumping in to save raunak
When he returned to delhi, he (without wasting a minute) retained kasturi investigations (a 'blue chip first class' private investigation firm) to research the material and when it was done, he got his manager to buy him all the material (available) and got first class tailors to sew him smart suits.
Unfotunately, double diaster struck-
he lost a lot of money (the suits were expensive);
he slipped on a banana peel (which kasturi had strategically placed) and fell down the stairs, he hurt his head badly and his injury caused him to
a)propose to kasturi
b)commit to paying off raunaks bad debts
Now both his commitments (marriage to kasturi and paying off raunaks debts) are going to proove to be VERY expensive...so with little balance in his bank account, he had only one option - take cheesy shows (or marmalade ones) and perform with his newly acquired fire proof wardrobe...the tears were because while his fireproof suit protected him, he (and we) could see his money burning and future burning in ways that he was not burning...if you get me drift
