My theory on this is that richard hillmans not dead, i recon he had an dead body in the river already that he paid for plastic surgery to look like him.
Then in his jacket he had an oxygen tank that he could swim to the other end of the river where he drove the car into, then got out the other side, into a near by car that he had already stashed there
Hope he does come back and sets fire to the house with gail sarah and david inside and bethney could be with emily in the end she could go and live with her dad.
