Under the influence

RKis denying his love for Madhu and trying to drown his need to be with Madhu with alcohol, in his room he keeps breaking speakers, dressing table, chairs every night, throwing things because of the memories of Madhu that he wants to forget, he doesn't want to need anyone to have happiness or wellbeing/content in his life. Bittuji will see him spiking Madhu's drink, playing dirty he wants her to embarrass herself at the party and with the shame not return to the set the next day, because of that 3 days challenge he doesn't want to loose to Madhu, so Bittuji who wants to reunite them and doesn't want his chief to spoil the relation worse spikes RK's drink and both will end up talli and speaking very truthfully about their feelings for each other.

With the spiked drink RK stop denying for that evening/night and he will let go of his ego...ask her to stay with him. So for once he will speak what's in his heart rather then listening to his head that just wants to play games with people.

However, when Madhu comes back to her senses she will remember all RK did, his ditching her the humiliation and insult and decide she doesn't want to forgive him after all so easily or she fears hearing more insults from him, when he is sober (the drug having worn off) , so she leaves his house whilst he is still sleeping to preserve her broken heart. RK wakes up not sure if he remembers what happened probably does but because she's done a runner he will blame the drug completely and not own up that in his heart he wants her back with him.

But waiting to see how it will be in the show, just anticipating...😉

I think he will pretend when he sobers up only that he doesn't remember what happened the night before, just to cover up his bruised ego, that he asked her to stay with him, to forget about their break-up and all the hurt but she chose not to stay with him, so to cover that up he will pretend that he doesn't remember. Too much ego, you know how he is...his hurting when he is alone in his room, but when he faces everyone he is putting on a mask of enjoying his life now that Madhu is not with him. So he will pretend he doesn't remember just because he doesn't want people to know that this time, Madhu chose not to remain with him.
