Hal has been accused of being 'childish' more than once in his life. It's not a title he usually feels inclined to dispute, largely due to the fact that all the important people in his life have enough evidence to shut down any attempt on his part to save face.

Besides. Isn't being 'young at heart' supposed to be a good thing?

All this to say, that Hal did not feel particularly bad about living his best life with Barry and Wally at Coast City's Enchanted Emporium amusement park.

Wally, the little squirt, got to have the time of his life, because Coast City actually knew what a good amusement park consisted of (roller coasters and water rides), as opposed to the state fairs that passed through Central, where the main attraction was a particularly good game of dunking for apples.

Barry put up with their shenanigans and controlled the tickets, because Hal and Wally would have certainly blown through them in minutes. He usually didn't go on the faster rides, because being a speedster apparently sucked all the fun out of them. It was a bit of a killjoy, because it meant they had to ride things like Ferris wheels (who did that anymore?) but Wally wanted to ride something with Barry and since Barry was such a good sport, Hal was willing to put up with his little quirks.

Usually, Barry spent the constant rush of Hal and Wally's racing across the park with little regard for strategy and no regard for the map with a constant bemused expression, making sure no one got lost, separated from the group, kidnapped, or succumbed to food poisoning.

Today, there was something pale and listless behind Barry's eyes, no matter how much he smiled when Wally informed him that someone was selling cookies bigger than his head.

Usually, Barry had the endless energy of a speedster, able to keep an easy pace beside Hal and Wally as they raced full-tilt from one location to the other.

Today, there was a sheen of sweat over Barry's face and a breathlessness Hal had never seen on him, save for when they were fighting the most exhausting villain.

Wally hadn't picked up on it, and Hal made sure to keep the kid distracted (an easy task, given the circumstances) but it was concerning Hal.

With Wally safely tucked away on a kiddie ride, Hal and Barry having promised to cheer and take pictures from the sidelines, Hal turned to probe his friend as to what was wrong.

"Hey, bud, are you doing okay?"

Barry jerks his head in surprise, as though he hadn't expected anyone to notice his subterfuge.

"Hold on a moment." Barry raises the camera to dutifully snap a photo of Wally as the ride starts, and Hal knows the picture will be painstakingly stored in one of Iris's scrapbooks later.

Hal hums a little to let Barry know he hasn't forgotten their conversation, and Barry, having taken a short video and continuing to snap photos, finally responds.

"I'm okay, really. I've just been feeling tired lately - we'd been promising Wally this trip for months, and I didn't want to disappoint him... and I'm really doing alright. Just…" Barry turned to flash Hal an exhausted smile. "Just tired."

Hal frowns. "You don't get tired."

"Everyone gets tired, sometimes."

"You're a speedster. You have inhuman endurance. You don't just…" Hal breaks off to wave a vague hand at Barry, "do this unless you have the black plague or something. You don't have the black plague, do you? Can you catch that kind of virus?"

"First of all, the black plague was caused by bacteria. Secondly, no, my immune system could handle it."

"See? There has to be an explanation here somewhere!"

"Let's just give it some time, Hal. We don't exactly have conclusive medical information concerning speedsters. Maybe I just… overtaxed my speed healing or something. Give it a bit. We'll let me rest up a bit, and everything will be fine."

"That," Hal reasoned, "would require you to actually rest."

Barry gives him a smile that says he'll try to rest until literally anything comes up and he throws health to the wind and sacrifices himself in a scarlet blur.

It's times like this Hal wishes his own track record were better, so he could nag Barry about his.

Wally's ride is now over, and he's running toward them, demanding to know if they saw him, how loud they cheered, and if he could see all the pictures.

Barry smiles and bends over to show Wally the photos, and Hal pushes the nagging worry to the back of his mind.

Barry will be fine.

He always is.
