Adi will suffer/regret when the truth comes out about Omi's death and Kavya had no hand in it.
There are also chances of Adi not believe Kavya was responsible for Omi's death. Because, he was there at the point of accident and saved Kavya's life and he must have seen the accident and got some hint, if not his trust on Kavya.
Yes, he may definitely not know about breaks failed, and he may think that Kavya jumped to save herself and let Omi die (the truth may be Omi pushed her to save her life and he died himself).
If Adi saved Kavya's life, and handed over to Bansals, then there must have been some tiff between Adi and Bansals, when she was in coma. Also, Kavya may get to know something after she comes out of coma.
So, it may be possible that, Adi acting as he hates Kavya and wants her to be out of his life, so that she can be safe and happy (may also be the reason for joining politics when he knows Kavya would not like it).
Also may be this time its a deal between Adi and Rajiv Bansal to let Kavya go out of Adi's life.
