Yeah I thought the same, but then today's episode took me back to the dinner table fight when Maithili was being torn apart by Mohini and Paro intervened. Rudra remained silent until Paro was gonna get slapped.
Here, Paro & Maithili got all the evidence of the laddoo poisoning, so he rightfully sat quietly and let them take the reigns since they obviously know about her evil ways more than he does, considering he was just hospitalized for poisoning. At least he told Mohini to not talk about his wife that way and encouraged the evil bat to eat the laddoo. The scene isn't even over though, so let's wait until Monday night and then discuss/critique/go nuts.
