Clark shook the offered hand. "Call me Clark," he replies warmly, "any friend of Kara's is a friend of mine." He glances over the crowd and nods. "I can speed them out and then come help you with the cavalry," he adds dashing into the crowd in a blur of blue and red. He doesn't really use the speed part of his powers much so it's a bit fun to zoom around pulling people out of the crowd and dashing them down the block. He's done in about ten minutes and returns as promised to start going through the things he can hit.
