What if Watt Tyler has effective bodygaurds while negotiating with King Richard at Smithfield?

It's pretty clear that in his negotiations with the Royal Party, Watt Tyler lacked sufficient protection for his person. That's why he got himself severely injured, that's why the Peasant's revolt ended, at that point, with their leader severely wounded. So, let's suppose that Watt Tyler has a force of bodygaurds accompanying him in his negotiations with Richard, just like Richard has. These bodygaurds will defend him, and discourage him from open violence against the Imperial Party, himself. So, when negotiations break down, there will be no significant violence. Both sides will simply withdraw. No collapse of the Revolt, no injury to Watt Tyler, no loss of leadership in the Revolt. What happens next?
