His companion makes a rude gesture and tries to follow, but can't figure out how to run across the surface of the water; he goes down with a splash.

With a fractured giggle, the boy in black and gold runs back to shore to help him up.

Unknown to the two boys, they have been watched for the last few minutes by a man in red, with a lightning bolt on his chest and a mask covering his face. 

As soon as he sees blue-and-silver start to fall, he starts towards the pair on pure instinct. Engaging with the kids wasn't the plan for today, but he's a hero, dammit. It goes against the grain to watch someone in danger of drowning and not help. 

He's too slow - not something that happens very often - and skids to a halt on the shoreline a few yards away. 

"Wow, you're fast."

Black-and-gold flashes a brilliant smile in his direction. "Thanks!" he says cheerfully.

Blue-and-silver hops out onto the shore, wet and grumpy but unhurt. "Oh, it's the middle of nowhere, you said," he mutters. "Nobody'll see us, you said." His mask includes an obscuring pair of mirrored lenses, but the tilt of his head and the tone of his voice suggest that he is rolling his eyes.

Black-and-gold shrugs unrepentantly.

They're the same height - less than five feet tall - and the same build, and their voices are very similar. Probably brothers, possibly twins.

"I mean, to be fair, I'm only here because I was already tracking you," says the man. 

"...wait, that sounded bad, didn't it."

...he cracks up. "Wow, nice."

"My brother is entirely to blame for the trail of sonic booms streaking across the countryside," says blue-and-silver.

"Hey, that's not fair. One of them was you."

"I was just trying to keep up! If somebody could muster the patience to stay below the speed of sound for ten minutes, we would've gotten here in perfect silence!"

"Heh. I was the same back when I first got my powers."

He shakes his head. "Oh, right, forgot to introduce myself. I'm the Flash, but...you probably knew that. Do you two have names? I mean, obviously you have names, everyone has a name..." 

"Warp," says blue-and-silver.

"And Impulse," says black-and-gold.

"Cool, cool. Nice to meet you both." He gives them a brief, careless salute. 

"Soooo, how'd you two wind up with superspeed?"

Warp points at Impulse.

"...once I found out that superspeed could be given to people, I wanted to see if I could do it. Turned out that yes. I promise to be responsible about it."

"Impressive. I mean, I did it, but I had J - my predecessor's notes to work from. You created a working formula from scratch?"

"It took me a couple years. Well, longer if you count the fact that I had to teach myself alchemy first. And chemistry, but they offer chemistry classes in high school, alchemy not so much."

He nods absently.

"How did you find out alchemy even existed? It's not exactly common knowledge." 

"Oh, uh - when we were thirteen we were at an ice cream place next door to a bank and I caught a supervillain about to rob the bank and talked him down. I promise it was way less terrifying than it sounds. He's an okay person, really, he was just having some problems in his life around then. I wasn't in any danger. And we kept in touch and he explained the basics of alchemy, but he didn't know enough himself to keep teaching me after the first couple of months."

"...Wow," he says again.

"That's really something. And you did that when you were thirteen?" 

He pauses.

"...how old are you now?"

"Seventeen!" he says brightly.

Seventeen, okay. That's not too bad. Batman's sidekick is younger than that, probably, he thinks. 

"So you're twins, then?" he checks while he starts figuring out what to do about suddenly teenage mini-Flashes. 

Sidekick...now there's a thought.

"Yep," confirms Warp.
