Had it been for anyone other than Umar - I'd say it was a smart move - if she managed to act it out well enough that someone left the task out of concern - without any kinda typical torture being used - I'd say well played.
But if it's done to target Umar, into guilting him - because he's taken an oath - that kinda makes it in bad taste IMO. Not cool.
I would say, if this season didn't have any doctors, I might have though it's a brilliant idea.
But the fact that Umar was there, it really does put him in a tough spot - you take your oath and you run to help and turns out it's fake and on the flip, if you don't run, expect to hear from both audience and Sallu/BB alike.
All in poor taste - Teja's just over the top, like she always has been.
