In the hospital, Sophia, who was chasing the Batman protagonist, or Karma as he called himself, had come to check on Kevin and get his confession regarding the fight that broke out in the outskirts.
They both knew each other so after learning everything, Sophia asked him if he made an enemy out of someone. Of course Kevin went ahead and counted Sunny Trevor, whom he beat and broke for chasing Meher, and the minister's lapdogs whom he cleaned up, and then came Ali, who was a psycho just like his friend in Kevin's eyes.
Their talks deepened to causes of enmity and Sophia ended up cursing Ali and explaining how she once saw him hiding a corpse and suppressing a murder. One thing to another, Kevin learned about the death of his father.
Obviously not the truth about Shiva, but that's why all the blame fell on Ali's head.
