The Setup: During one particularly violent scuffle, the blind man grabs Alex and beats the ever-loving crap out of him. His hands find a pair of hedgeclippers nearby, and he plunges them into Alex's chest, leaving him to die.
The Second Twist: It's not until later that we learn Alex has survived. At the last second, he'd moved behind the dead body of his friend Money, who was lying nearby. The hedgeclippers are in Money's chest, and not Alex's.
