The other major downside is that Sushma now knows where Jyoti lives, and is in a position to blackmail her. Although I think that tomorrow, she wont do it, since she has as much to lose if she's exposed in front of her parents as being a maid to Jyoti. Granted, she'd do anything to damage Jyoti, but here, the collateral damage to herself is too high.
What I do wonder is whether Sushma will want to come back, given that she'd have to face her hated Jyoti everytime, and suck up to it just so that she can keep her 'household' running. Of course, Tuesday, if Brij is hauled off to jail and she returns to Padma, then her predicament is partly solved, but then she better hope that cm never visit that house or if she does, that she not see her, or she'd be subject to questions of why she didn't bother showing up. To date, cm has never been to that house (Mahendranath was there the first time Thursday/Friday), but if Sudha and Uday get engaged and a ceremony happens there, she'd have to go.
As it is, it was sad that Jyoti couldn't really enjoy her Diwali, since she was obsessed by Sushma's largely self-inflicted plight, but what was worse is that she made every attempt that Sushma not see her, but Sushma saw her after all, spoiling everything for her. Only saving grace is that Sushma is unlikely to be stupid enough to create a scene right there, since Brij warned her against it, and also, that her entire family would see that she's working as a maid in her hated step-sister's house.
