what i saw in the show that made me think that raj could use sudha's voice in a song, with rhea fronting:
* at the end of rhea's recording session, when rhea asks him how it was, raj looked like he didn't know what to say first. then he looks at sudha, and for a brief moment, there was a light in his eyes, and he started praising rhea to the skies.
* sudha telling raj that only people with good voices deserve to be heard/get fame, etc. that seems like oneof those obvious lead-ins: where, sudha herself will give up on her beliefs about rewards going to those who deserve it, all for the sake of love.
* the line in the original promos: sudha singing with a smile on her face "yeh bhi kya preet hai, haar mey jeeth hai" while raj looks terrible and uncertain.
but in his defence, i think that raj does not understand how obsessed rhea is with the idea of getting her own way on this. rhea has fought with her father (who she worships) to get this chance. rhea is desperate to show her father (and now mr. big-mouth nikhil) that she can be successful in her own right, just like her father is. remember that line: "from now on, they will say mr. surjit sahani, rhea sahani's father."? rhea is really desperate for success to show off to her father.
raj doesn't get this, i think. he thinks that all girls are like sudha - he probably thinks that rhea is ambitious like himself, but he probably doesn't know that unlike him, who will only pretend to do mean things to get his way - like pretending to take money from that sleazy property developer to free the school - rhea will probably do everything to get her own way, including using emotional blackmail - threats to kill herself - to get her own way. and unfortunately for raj, rhea is convinced that raj will get her all the success to show off to her father.
one way this could go is that raj will think that once he gets rhea to be successful, he can leave her and take up sudha's career as he always meant to. but rhea will not let him go. i think that rhea might even actually fall in love with raj - after all, everyone falls in love with raj! 😳 - and want him to leave sudha, so that raj will concentrate only on her and her career.
oooh, i am sooooo looking forward to how this story moves forward, and how it ends. 😊 i'm even more glad that fox tv is not planning to have this show go on and on and on like kyunki or even kutumb and the other balaji shows....
