Tarik hit the brake control on the steering device, not abruptly enough to throw us out. He and Iris didn’t slide forward because I grabbed the safety harness of Iris’s environmental suit and ART-drone grabbed Tarik. (Not so much grabbed as leisurely lifted an arm and extended it across his chest .02 of a second before the jolt as the vehicle stopped.) Iris glanced back at me, startled, and then smiled. "I forgot how fast you are."
