Kid Flash that whole time was busy. He was knocking out prisoners one by one either with punches or kicks. Occasionally he would use the shock of his gloves to take them down. However, when he got the little message he grit his teeth. "Damn... And here I am breaking a sweat." He said to himself as he began to slam himself into the remaining prisoners like a cannonball. "Alright... D-done..." He said panting a bit. It only took a minute, but that took a lot out of him. He opened one of the compartments in his gloves and ate the food in it. One more compartment left." He said as he cracked his knuckles and popped his neck. He smirked and raced off to the "Playground" standing still the moment he stopped. "Alright! I'm here! Let her go!" He demanded making it obvious he'd give up if it meant saving her. Odds were there were more than just one left standing who could take out Red Huntress if he tried something stupid. 

(Meh it's fine lol Wouldn't be a good "first" mission if something didn't go wrong lol)
