With Batman off world and Alfred at the manor sick, Dick, or rather Robin, had been sent to the Watch Tower so that he could be supervised. Flash, Superman and Green Arrow were the 'responsible' adults that were supposed to be looking after him for the day and a half before Batman was due back. They weren't exactly Batman's first choice (at least; Green Arrow and Flash weren't) but there wasn't many other options. Of course this 'responsible adult supervision' resulted in a major prank war, with Flash and Robin teaming up against Green Arrow. Superman had wisely disappeared when the paint first started flying.

It only took an hour for Green Arrow to be covered in pink glitter, neon paint, and a sparkly princess tiara sat squint on his head. Easy to say Green Arrow was not very impressed. Yet, he had been struggling to get the Speedster and Boy Wonder back - both were very skilled in the art of pranks. The prank war was unfortunately very one-sided, so when Superman wisely caused an end to the war Green Arrow was very relieved.

That meant they had to come up with a new way to entertain the young kid. Having learnt from his first time babysitting, Flash decided to let Robin have a go in training room with the trapeze, volunteering to act as spotter. Robin instantly went for the trapeze, despite the occasional trips to the Watch Tower (mostly for his mental training with Martian Manhunter) he had yet to actually use the trapeze. Flash watched amazed as the young hero seemed to fly across the room, any other League member that stopped by was similarly amazed. They were finally starting to understand why his name was Robin.

Once he had finished his display on the trapeze he managed to convince Flash and Green Arrow to spar with him. He managed to knock Green Arrow to the floor a few times and even gave Flash a bit of trouble during their match. The pair was impressed with the young hero - if he was already this capable at this age what would he be like as he grew older? That managed to occupy several more hours before Robin started getting twitchy and bored. Superman (who had reappeared at some point) came up with the idea of letting Robin have a go at upgrading their systems as he had continued to complain about their lack of security every time they met.

Eventually they managed to waste the day away and tire the boy out for the night. That only left about 9 hours before Batman should be back from his mission - not too long to entertain a small child for, right? Wrong, it was still morning and already the three heroes had run out of ideas. Superman managed to escape as it was his turn on monitor duty, leaving the babysitting duties to Green Arrow and Flash which probably explains the trouble that followed.

Green Arrow had come up with the brilliant idea of a mini-competition. A series of small meaningless but fun challenges for the three to undertake. Flash (unsurprisingly) won the race across the Tower, Robin one both the acrobatic challenge and climbing challenge and Green Arrow had yet to win anything. Their little competition had managed to draw the attention of some of the other heroes that were wondering the Tower - in between missions or simply relaxing amongst peers and friends.

Green Lantern had come up with the latest challenge; to see who could hold their breath under water the longest. The group (mainly Robin with his puppy-eyes) had convinced Black Canary and Superman (who had finished monitor duty) to take part alongside the four of them. They had even managed to convince Martian Manhunter and Wonder Woman to act as supervisors and judges.

The only rules were no cheating, no using powers, and no sabotaging anyone else. Once they had all gotten dressed into swimming trunks/costumes (Robin didn't have any with him but his uniform was waterproof so had simply removed cape and utility belt) they made their way to one of the two Olympic-size pools that the Watch Tower hosted (the fresh water one not the sea water one).

The six competitors waded into the water and found a space in the water, waiting for the signal to start. Martian Manhunter counted down from three and they all dived down below the surface. Martian Manhunter and Wonder Woman watched on from the surface, both judging and prepared for any emergencies. After about a minute and twenty seconds Green Lantern re-surfaced and made his way to the shore where Wonder Woman handed him a towel. About thirty seconds later Green Arrow followed and then Flash fifteen seconds after. Superman came up next only ten seconds later. Black Canary was the last League member to surface another thirty seconds after Superman - a total time of 2 minutes and 45 seconds. Not bad but Wonder Woman made a note that they should probably do some more training in the water.

The only one left underwater was Robin. The League members watched from the side, getting more nervous the longer the boy stayed under. They knew Batman could hold his breath for a fairly long time but Robin hadn't been training that long -surely he should have come up by now? After a full minute had passed after Canary came up, Aquaman entered the room. He had heard the commotion from the corridor (Flash had started chattering nervously) and had come to investigate. He found seven senior League members (all well experience heroes) watching a small colourful child underwater in the middle of the pool nervously from the side.

"What's going on?" He asked, giving a few of the League members a fright as they hadn't heard him come up behind them.

"We were having a small competition; seeing who could hold our breath the longest but Robin still hasn't come up and it's been about four minutes now." Superman explained, trying to remain calm.

Aquaman glanced back at the young boy in the water. He had heard about Batman's young protégé, he was sure the kid was very capable but he didn't want to face Batman's wrath if anything happened. "I'll see if he's okay." Without waiting for an answer, he dived smoothly into the water and made his way to the young hero.

The boy glanced up as he saw the hero approach, offering a wave. Aquaman waved back unsure; clearly the kid was okay but he wasn't sure what to do know that he was actually facing him. His confused face must have been a sight as it caused Robin to try to giggle; his hand flew to his mouth to stop him actually doing so and losing his breath. Robin pushed off the floor of the pool and darted towards the surface. Unlike the older heroes he didn't immediately gasp for air he just started giggling (which confused the seven heroes watching from the side).

Aquaman joined him at the surface as the younger half of the Dynamic Duo made his way to the side and pulled himself out of the pool, sitting with his legs dangling in the water. He turned his head to Martian Manhunter (who held the stopwatch). "How long was I under?" He asked the gaping heroes. Martian Manhunter was arguably the calmest and answered with a small smile. Robin had been under for four minutes and 48 seconds. The boy nodded, smiling at the time before turning back to Aquaman who was still standing in the pool, water up to his chest.

"Hey, you're Aquaman man right? It's nice to meet you." Robin asked, grinning at the hero.

"Yes, it is a pleasure to meet you as well Robin. You are quite skilled under the water." Aquaman nodded at Robin's thank you before starting to swim. He had been on his way to the pool anyway before getting side tracked by the commotion.

Robin watched him glide through the water before pulling himself to his feet, grabbing a towel and facing the other heroes.

"Ha, told you you'd lose GL!" He laughed, grinning at said hero as he left the room. Once he left the older heroes seemed to unfreeze all moving to follow him, some more rapidly than others.

"Hey! Get back here kid!" A cackle was heard in reply, leaving the rest of the heroes laughing at their teammate being beaten by a kid. Not that it was completely unexpected - it was Batman's kid after all.

About half an hour later, Robin had managed to ditch his babysitters temporarily and made his way back to the pool. The earlier challenge had made him want to go for a swim. Aquaman was still doing lengths of the pool and had yet to notice his entry. Robin watched for a few minutes, entranced by the way the aquatic hero moved through the water. He waited until the hero seemed to take a break, pausing at the shallow end of the pool and stretching.

"Hi." Aquaman gave a small jump at the sound of the quite little voice. He turned his head in search of the source of the voice, finding Robin standing slightly nervous at the side of the pool. "Do you mind if I join you?"

"Of course, you are always welcome." Aquaman offered a smile as the boy entered the water, coming to stand next to him. He watched with a raised eyebrow as a mischievous grin made its way onto the young hero's face.

"Hey! I'll race you twenty laps starting...now!" The boy challenged as he swam off at speed, not giving his competitor any time to react.

Aquaman tried to go slower for the bird's sake, but quickly found himself having fun and wanting to beat the little boy.

And that was how Aquaman met Robin, through a day of challenges. Whenever Robin was at the Tower and had a spare hour he tried to find Aquaman for a swim and eventually admitted to knowing the heroes identity. He even revealed his own, confirming Aquaman's suspicions on the kid's identity (Bruce adopts a kid and then suddenly Batman get's a kid protégé - it wasn't that hard to put together if you knew Batman's identity).

Soon after he became Uncle Orin and was often seen teaching the boy cool water tricks and racing him.

Like all the other League members he found himself starting to love the boy like a nephew and looking forward to spending time with him.

Yes, it seemed Robin was too cute to resist.
