Iris glanced at the window behimd her and laughed as well. "Lets try our best not to break it." 

She noticed he seemed ready to go but was not interested in making the first move, so she figured she'd start off the match. Using her speed to approach him, she quickly spun around to build up momentum for her attack, though at the last minute, she crouched to aim for his feet. This was a test of his speed as well, Iris was hopeful he would dodge this and execute a sucessful counter attack.
