Christ. So this was the finish. A brawl. A riot. A fight with every man for himself. Bloody heads and eyes cut with broken bottles. (3.2.2)
This riot acts as a fitting conclusion to Jake's chaotic, and often violent, storyline. The fact that this riot devolves into "A fight with every man for himself" tells us that though violence often arises out of a sense of solidarity, it quickly turns into something more ugly. Jake was hoping for revolution, but he is met with violence that is completely and totally selfish. And terrifying.
