Watched the Radhika/Dida scene again. The reason why it looks obsessive is because she was planning a wedding and bringing the pandit over. Her points to Radhika were valid though.
Radhika asked questions that forum members ask - Ishaan has done so much for Mauli, Mishti loves Popsie, what if Kunal cheats again, etc... and Dida answered ALL of those questions and had the last word. It wasn't a back and forth argument session... Radhika was asking questions and Dida was answering them... it's like they're tying up the public's questions with answers through Dida. So hope is still on for Maunal.
