The sympathetic nervous system is responsible for the body's "fight or flight" response in times of stress or danger. In this situation, when Rory was being threatened by the two men, her sympathetic nervous system would have kicked in, increasing her heart rate, dilating her pupils, and directing blood flow to her muscles, allowing her to make a quick getaway.
