At the impact the sign stung Percy's hands and he almost lost his grip. The troll reacted by kicking out and right into a man nearby. They had to get this troll out of here.

Suddenly Fisk was by his side a piercing whistle crossing her lips. Percy raced to catch up with her, "We have to get him back to the Park!" Or really anywhere that didn't have people. Someone should go ahead, now that the troll's attention was caught. "Can you warn people ahead of us?" Percy had just started saying as they began to jog down the street, the sign still in Percy's stinging arms, the troll's heavy steps behind them, when a large troll hand knocked him and Fisk down.

That hurt. Trolls hurt. He had to get back up. Percy struggled back to his feet, looking at Fisk. He couldn't guarantee he'd get her out of the way of the troll. It took a step toward them and Percy pushed himself toward Fisk, managing to get to his feet and wrap an arm around her to drag her out of the way.
