I guess it was a scene crying to be misinterpreted. Radhika alone with Arjun, holding his hand, looking as though she didn't want to let go and Arjun looking stiff with rejection.
What was Sam to do, especially when she was under Nandini's spell...that cool, sophisticated worldly woman and her beloved's beloved sister to boot? so, sam felt Radhika was chasing after him, forcing him to listen to her.
From Sam's pov, this looked very threatening to her relationship with arjun and what is hers is hers...she reminds me of her attitude towards Radhika when the latter joined Bird Song before things became better between them.
As for Arjun dancing happily with Sam, well, the situation demanded it, I guess. There he was on stage before all and sundry. surely, he couldn't possibly look reluctant and disinterested. I suppose he has supreme control of his feelings which is why nobody else other than nandini, who knows him well, recognised them.
Didn't get Saral's volte face though. I thought he knew about Nandini's hand in the arson..weren't they in cahoot's in Thursday's episode?😕
So,, now he's in Team Radhika. Will Bonnie join her too? and Neil.
As for Neil,it's time to get his act together and stop being Devdas. Hopefully, he'll believe Radhika and save sam from this jam and restore her faith in radhika.
