Rider
Rider found herself impressed by his acrobatic avoidance of the attack. She knew he was a skilled and fast rider already, but she hadn't expected him to possess her skill in avoidance also.
She smiled at his comment, amused and slightly flustered by the dominatrix part. She kind-of wished she'd made some kind of bet over the result of the race, dominating him and punishing his hubris would have been fun and, even had she somehow lost, she would likely have enjoyed the reversal as well.
"Oh, a dominatrix, am I? Does that mean you want me to dominate you?" she responded with a smirk, hoping to put him a little off guard as she continued to race.
Her previous maneouver had lost her the lead, but she was sure she could out-pace him. However, she also knew that, were she to overtake him, he would simply resort once more to his previous tactic.
So, as they reached the turn, Rider jumped off the roof and, waiting for him to move out from behind the truck, she launched another attack. This time, though, she only threw one of her nails at his wheel. The other she held back, waiting for his evasion attempt. Then, when he was in mid-air, she would take aim once more, intending to send the chain through any gap on ther bike and into the road behind. If it worked, his momentum would send him flying off the suddenly-stopping bike, and the bike itself would likely be damaged beyond repair.
