It takes place after Pragya's birthday party...
Robin watched silently his pragya mam being humiliated and insulted by tanu and her boyfriend in her birthday party. He was so angry on all mehras and especially on abhi sir and his dadi for not supporting her and watching silently her being insulted. First time in his life he felt small and regretted being a servant. His abhi sir didn't trust mam and believed her affair. He was so angry on sir but he understood his POV also. He knew that his sir was also trapped in the plan by evils.
"tum ne ye achha nahi kiya tanu aur Nikhil. Tum ne meri mam ko badnam kiya he.me tumhe chodunga nahi. Tumhari sachhai sabke samne launga." he thought for the whole night and decided to execute his plan next day.
When next day he noticed Nikhil entering MM silently and walking towards Tanu's room, he deliberately spilled juice on his coat just before Tanu's room and then he rushed away without apologising. Then as he planned, he started recording the video of Nikhil entering Tanu's room. He changed his coat and when he was leaving tanu his clothes were changed and robin also recorded when his hands were on Tanu's back.
After recording the video, he went to abhi and told him that he doubted their daily meetings and on investigation he found this. And he also told that he isn't ashamed of his doing because he has done everything for abhi's goodwill. Abhi silently nodded.
Abhi called tanu to his room and asked her,"what the hell is this tanu?? What was he doing in your room? Why he changed his clothes? Why his hand was on your back? Are you hiding something from me?"
Tanu was shocked and frightened but she still tried to lie,"this is all lie abhi. Someone is trying to frame me."
"this is recorded by Robin. What animosity he has with you that he would frame you? Tell me the truth. "yelled abhi.
Tanu told abhi about juice and how she was helping Nikhil and she told him to ask robin but when abhi asked robin about spilling juice on Nikhil, robin denied instantly. Robin told that he didn't about any such thing. Tanu goes pale hearing that. She was smartly cornered by Robin. She had no choice left other than confessing the truth. She was about to admit truth. But suddenly dadi came there hearing all this noise come to abhi's room.she heard about Tanu's video but didn't hear full conversation. She thought tanu will not admit the truth and blame robin for framing her and we have no solid proof now and i can't take anyone's side openly. if tanu escaped today then she will use this incident as an excuse in future when we will expose her. What to do now??she thought to end the matter for now.so, she took abhi aside and again feeds him the same theory of Pragya's affair theory and tells that tanu is also trying to make Abhi jealous. Abhi refused to believe dadi's stupid talks but dadi still tried. He was too confused. Everybody was giving him different-different advise. He didn't know whom to believe.he was so tired of this fight. So he returned to his room and asked everyone to leave him alone for some time and relieved tanu stormed away to her room leaving behind a furious robin burning with rage. He was so angry on dadi for ruining his well executed plan and he vowed to not let takhil go away so easily. He sweared to expose them soon but before that he decided to settle his score with the dadi first because she is the biggest hurdle in Abhigya's happy life and retired to the kitchen thinking of his next plan.
