World: Justice League (Unlimited)
Summary: A drabble about how Flash may or may not be afraid of lightning
While taking his teammates to a pizzeria to celebrate a successful operation to save the world, Batman found himself very thankful for his abundance of earthly possessions. If he weren't a billionaire, he would never be able to afford to feed the Flash; at least, not in the long run.
He couldn't help but wonder how Wally managed to keep himself fed.
In fact, the longer he thought about it, and watched the Flash make plate upon plate of pizza vanish into the black hole that he referred to as his mouth, the more contemplative he found himself. And worried. Could the Flash actually keep himself fed? He was rather thin, now that Batman actually looked. Of course, some of it was an illusion caused by the amount of muscle on the man, and fat would never be able to take a hold of someone with a hyperactive metabolism. But even so, the speedster could use to gain a bit more weight; to eat more than he already did on a more regular basis.
In the end, Batman skipped the part where he would check whether or not Wally's job paid enough to be able to feed him properly, and just went straight to the part where a few different delivery services started to deliver big parcels of food to his doorstep every day.
He admitted nothing when the Flash asked around the tower about it, and just secretly felt pleased when Wally slowly but surely started to look healthier.
