"So, what trouble did you get into to make Mr. Nice Guy attack you, huh?" The Harbinger asked right before blowing a raspberry on his sibling's neck. "EHEHEK!! Nothihing... he was just beheing a meanie..!" The kid whined, still laughing from all the tickles he had received. "Ooohh is that so?" The taller guy asked with a glint of mischief in his eyes that made Aether shiver as if he was in Snezhnaya.

Teucer nodded quickly while his brother put him down and marched towards the blond, who was so antsy that couldn't even get up. Childe pinned him down easily, so easily that it was a shame it didn't count as a real fight, and told the kid to get closer. "Now Teucer, what about if we take a little revenge on this meanie?" He grinned evilly, even though his expression softened when he saw his brother's eyes sparkling with playfulness and joy.

He made the child straddle the Traveler, who had already a giddy smile plastered all over his face in anticipation. "Hmmmm... where to start..." he asked himself while poking all over Aether's torso "I know! Teucer, wiggle your fingers on the crook of his elbows... yeah, like that- no wait, a bit softer... that's it." The Traveler was giggling already, knowing what his... let's say frenemy was planning.

Following Tartaglia's instructions, the little redhead started slowly dragging his fingers down, towards the underarms, laughing a bit when he heard the guy under him squeak. The amber-eyed guy, on the other hand, couldn't keep his laughter in at all. As soon as the child reached his armpits, the dam broke.

"Nahahahaha Teheuceheher wahahaihit!! Pleheheahase behehehe nihihihhice..!" Aether's high-pitched laughing echoed on the mountain. "But if you're laughing, it means you're enjoying it, right? That's what you told me earlier." The kid smiled innocently, to the point that Childe didn't know if it was supposed to be a comeback or just a consideration, but given how much the blond was blushing, he was proud nonetheless.

"You're absolutely right, and look, he's blushing..." the taller guy cooed in fake sympathy "Even his ears are getting red! Listen to me, try to massage the lobes with your fingers and scratch behind the ears as if he was a little kitten." The Harbinger gave more evil instructions, which the child executed immediately, laughing at how Aether was trying to scrunch his shoulders.

"That's it, now switch between his ears and neck, and if you want you can go back to the underarms. Just do whatever you want." Childe smiled lovingly at his brother, who was having the time of his life being on the giving end for once.

The guys found out that Teucer was unexpectedly mean. He switched quickly between the spots to not let the Traveler get used to the sensation, made him scrunch one side of his neck to attack the exposed one... and the list went on. It seemed like he had gotten his brother's genes after all. They went on for five minutes, until the older brother had another idea. "Teucer, do you know how many ribs we have?"

The kid knew the answer, since all his brothers had played that game with him at least once. "Twenty-four!!" He exclaimed with a big smile on his face... only to be corrected by the older redhead. "Nuh uh, it's thirty, fifteen on every side." He said casually, as if he wasn't planning on pulling one of the meanest tricks ever. "Just count them and you'll see I'm right. But take your time, you don't wanna lose count, do you?"

Had Teucer understood the plan and was playing along? Probably, but no one will ever know. What's certain is that he started immediately. "One... two... three..." He went agonizingly slow, so much that the blond arched his back and bucked his hips reflexively, almost making the kid fall.

"Woah!" The little boy managed to keep himself steady "Brother... I think I've lost count. Can I restart?" He asked, making Childe snort and Aether shiver again. "Of course you can, we have all the time in the world..." The older one replied, lowering his head to whisper something into the other guy's ear.

"If he falls, you're gonna regret it." He simply said, making him stop squirming, although not completely (that was basically impossible), while the kid resumed his important task with extreme precision.

"...and twenty-four. I was right hehehe" Teucer said with a triumphant expression while scribbling again under the Traveler's underarms "You're so silly, brother" He taunted. "What..? It can't be... impossible!" The Fatui member exclaimed with a fake dramatic tone. "I think you should count them all over again, just to be sure." He stated, which made Aether squawk.

"Nohohoho dohohon't lihihistehen toho yohohohour brohohotheher!!" The amber-eyed guy begged, but Childe gasped feigning disdain. "Don't listen to your brother?! What kind of advice is that? Who should he listen to, hm? To the evil man who called Mr. Cyclops a killing machine? And to think that I left him under your responsibility... you need to be taught a lesson." He decided. The blond gulped between his giggles, Tartaglia's tone was way too ominous for his own liking.

"Teucer, this is gonna be the final blow to complete our revenge, so let's make it memorable. Watch closely what I'm doing." The Hydro holder moved Aether's arms under his knees and unleashed a merciless attack on the latter's tummy and sides, which were unfortunately his death spots and, more unfortunately, perfectly exposed. He poked and scribbled on the tummy, squeezed and kneaded his sides, pinched lightly his lower tummy and repeated the cycle irregularly to keep the blond on his toes.

"NONONOHOHOHOHO HAHAHAHAHAHAHAHA PLEHEAHAHAHSE NAHAHAHAHAT THEHEHEREEE" The shorter guy went berserk, but tried his best to not buck the little boy off, not wanting to find out if Childe's threat was true or just a bluff.

However, things got even worse when another pair of hands joined the fun, trying to imitate the Harbinger. Twenty fingers on his death spot? Aether howled. "NAHAHAHAHAT THIHIHIHIS!! OHOHOH AHAHARCHOHONS!!" The Harbinger laughed wholeheartedly, and got another idea. "Now repeat after me, tickle tickle tickle..." He told his brother, who repeated it quickly. The two brothers kept saying it, making the blond become crimson red from his neck to the tip of his ears. "PLEHEHEAHAHAHAHASEHE NAHAHAT THIHIHIHIHIS!!"

"Not this? But it can't be that bad..." Tartaglia pondered "Imagine if someone were to find out that your giggle button is super effective... now that would be bad." He didn't even need to look at his little brother to make him get the hint. By the end of his sentence, Teucer had already dipped a finger in Aether's belly button, wiggling it and moving it up and down as if he was pressing a little button.

"TEHEHEHEUCEHEHER THIHIHIS IHIHIHIS NAHAHAHAT NIHIHICEHEHEHE!! YOHOHOUHUHU MEHEHEAHAHANIEHEHEHE!!" The shorter guy screamed, a tear running down his face, which was as red as a tomato. Seeing that, Childe understood that it was time to stop, but there was one last thing he wanted to teach to his little sibling.

"Now, for the grand finale..." He said theatrically "We're gonna use the ultimate weapon, feared even by the best and bravest employees of the toy factory!" He announced, making Teucer even more excited. "Now put your lips on his giggle button and blow like I do on your neck." He said.

The little redhead quickly obliged, but he'd never blown a raspberry, so it took him a few attempts to get it right, much to Aether's dismay, since the first little blows were already enough to make him jump and squeal. "Nonononohoho EEK!! Teuhuceher ple- EEK!! Pleheahahase dohohon't... EEP!! Ihihit's gohonna behehe so ba- WAAAAAAHAHAHAHA NOHOHOHO IHIHIHI GIHIHIVEHEHE!! YOHOHOHOU WIHIHIHIN!!" He surrendered, feeling his stamina reach its limit.

The two brother let him go and waited for him to recover. "Look brother! Mr. Nice Guy's got the giggles!" The little kid cackled while the shorter guy was getting rid of the remaining tingly feeling after the mean attack. In the meanwhile, Tartaglia laid next to him on the grass and put his brother on top of him, to make his head rest on his chest.

"So," Aether spoke after regaining his breath "did you have fun, Teucer?" No one replied. "Teucer? Are you lis-" When the blond turned around, he found the child fast asleep on his brother's chest, looking peaceful and cozy.

"Poor kid, that tickle attack must have tired him out..." Childe said, as if Teucer had been the victim, earning a deadpanned look from the Traveler. "Anyway, I have work to do, so please let him sleep with you." The Harbinger asked while trying to get up, but when he tried to pass his sleeping brother to the shorter guy, the child wrapped his arms around his neck and whined in his sleep.
