Jacked reflexes

Jacked reflexes: "I am Jack's hyperactive neruons." Once per scene or encounter you can retest one roll where your reflexes would otherwise have failed. This can be for an initiative check, some saving throws, or checks and allenges of Wits or Agility. "Like I told my last wife, I said, 'Honey, I never drive faster than I can see. Besides it's all in the reflexes.'"
