My prediction:
Malini and adi mein kuch argument hoga, malini madam will get upset. Use manane ke liye, he will decorate his room and wait for malini to come. He will hear a noise of someone entering the room, close his eyes and blurt out I love you or might even hug her. 😉 When he will open his eyes, he will be shocked to see imlie standing in front of him. Malini will notice it from behind and say her famous dialogue "Yeh kya chal rha hai". 😲 Adi n imlie will be caught in an embarrassing situation. ☺️
Imlie holding a knife doesn't make sense in my prediction story. 😆 Kya pta isse pehle dikha de imlie kitchen mein vegetables chop kar rhi thi. That's why she was holding knife. 🤣
After the embarrassing moment with adi. Like as always imlie will be delighted to share an intimate moment with adi, Malini might notice imlie's reaction after such incident. Like yeh itna khush kyu ho rhi hai. Hence, it can justify malini's doubtful reaction as per precap seeing imlie happy on adi's love confession. 😛
