The shout was something like a trigger, immediately sending the group of youths that was blocking the path of both Jack and Henry into action. Since Jack was the one who had gone through them, they immediately went to attack him.
A few of them remained behind, considering that Henry had not yet made his move all this while. They had to deal with all of them, and so, three of them remained so that they could hold back Henry.
As for the others, the moment that they approached Jack, they did not hold back at all. They did not care about the people in the surrounding area, but instead, they simply focused on Jack.
Punches and kicks were thrown at Jack. It was clear now. They were here to cause trouble, and they could no longer create the façade that it was Jack and Henry who had started it.
