The cave was silent. Aqualad and Artemis were spending the night at their respective homes, taking a day away from the superhero world. Miss Martian and Superboy were out on a training mission, leaving all but two rooms at the cave vacant. The two room's occupants, Robin and Kid Flash, were dead to the world and enjoying their uninterrupted sleep.

They had spent their day in a joint training session directed by the Flash and Batman. On their own, each mentor was relentless taskmaster who wouldn't allow their students to stop until the task had been completed. Together, they created a training session that would be difficult for most of the league. Their students were pushed to their limits, learning to adapt and push past all exhaustion. By the end of the day Robin and Kid Flash had no desire to make the journeys back home.

Through a mixture of manipulation, begging, and puppy-dog eyes (from the boy wonder) the boys managed to convince their mentors to let them stay the night in the cave. While the Flash and Batman were reluctant leave the boys alone in the cave (Black Canary and Red Tornado had league business to attend to and wouldn't be in the cave that night) they knew the boys were exhausted enough that they wouldn't cause trouble. Once the boys were free of their mentors they raided the kitchen and plopped down on the couch. They played video games, watched movies, and spied on the league until they could no longer keep their eyes open.

They parted way for the night and made their ways to their respective rooms. Kid Flash collapsed onto his bed and immediately fell asleep, not bothering to remove his costume. Robin took the time to take off his costume, but left his mask on. While Kid Flash did know his secret identity Batman didn't know that, so Robin slept with his mask on.

Robin and Kid Flash's sleep was deeper than usual because of their hard training. They both felt safe knowing the other was nearby and the mountain was nearly impenetrable. These factors led the boys to sleep deeply enough that they would be unawaken by anything short of a bomb. For this reason, neither of the boys would have aware of the man sneaking into the mountain, even if he had made noise.

The man walked down the halls towards Kid Flash's and Robin's rooms, making no noise except for the faint sound of his breathing. He reached Robin's door first.

Robin bolted up, not knowing what had woken him but knowing that something wasn't right. He couldn't see anything amiss in his room, everything was as he left it. He pulled his utility belt off the nightstand and put it around his waist. Better paranoid than dead, as Batman said. Robin slowly got out of bed and walked towards the door, intending to wake Kid Flash and check the rest of the mountain. Every instinct Batman had drilled into him was telling him that something was wrong.

He heard something creek behind him and he spun to face it, batarang in hand. Nothing was in the corner. He lowered the batarang and an arm was thrown around his chest as a cloth was held to his face. Robin held his breath, knowing he didn't want to breathe in whatever was on that cloth, and struggled against the man holding him.

The man was strong, strong enough Robin couldn't break his hold. The man quickly jabbed his fist into Robin's stomach, forcing all air out. Against his will, Robin took a breath and that breath was his undoing. The chemical worked his way through his system rendering him limp and unconscious in the man's hold.

The man dropped Robin, smirking. He exited the room, knowing he only had one boy left.

As soon as Kid Flash heard something hit the floor, he was out of bed and moving. In his sleep muddled state it took him a millisecond to realize he had slammed into the door and was now sitting on the floor. He got back to his feet and wondered why the door wasn't opening. He stepped back, preparing to kick the door down when he smelt something.

Kid Flash paused, taking another breath to try and determine what the scent was. Too late he realized it was a gas and while it wasn't any gas he knew of, he could feel its effects beginning. He held his breath but it was too late, his vision was fading and he felt his knees give out. He tried his best to remain awake, moving his body as much as he could to try and force the gas out of his system. However, his efforts were all in vain. He could hear more gas being pumped into the room and seconds later the world around him disappeared as he succumbed to sleep.

Outside the door, the man smirked. His plan was going perfectly. The two sidekicks were out, and now his work could begin. Although his original target was Robin, he wasn't going to turn down the other sidekick that was practically giftwrapped for him.

The man slowly walked out of the cave singing under his breath, "Are you hungry? Are you thirsty?"
