In terms of aditya, if teh CV's are going to show that he is a vallian, the justification could be his envy for anukalp since anukalp benefited from the love of his parents and a comfortable life unlike him he had to settled for kekti and his other life. He is human and humans do react in such ways when affected. I see it happening in everyday life in the world today.
Regarding ramya supporting his plans, it can be and i dont think anyone would have believed her about aditya's negativity at that time, so she decided to do it the other way so that people can actually see the truth rather than her telling it.
I would be happy if anukalp returns and the RMJ reunited in the end as any jodi created by god should end in a positive way.
