A/N – Yeah, I'm obsessed, get with it everyone because I'm hoping on this bandwagon and I hope to stay on it till the series is finished. And, because Klaus is my favorite kid, I have to put him through some angsty things and hurt your feelings. Don't worry, I'm hurting my feelings too. Oh, and Ben is the best boy, so he gets to be up there with Klaus too!

Okay, so basically the premise for this story's making is something that their father said to Klaus when he (spoilers) died at the rave: "You've only scratched the surface of your potential." Basically, this has become a theorized version of some of Klaus' potential brought forth through unconventional methods! So, peace out everyone and I love you all, thanks for supporting me joining the Umbrella Academy fandom.

Set about a year or two after the season one finale when they are turned back into children.

Chapter 1 – Finding Klaus

Ben woke up late that morning – his clock told him it was almost eleven. It was almost surreal waking up past the time their father used to set for them. However, due to some certain circumstances – everyone in this house now has the mental age of an adult – Sir Hargreaves has been quite lenient towards him and his siblings about, well, everything. He was actually pleased with how things had turned out despite his family causing the apocalypse in the future; Ben guessed it was because Sir Hargreaves liked them better as adults.

Well, whatever the reason was, it's given Ben the ability to sleep in – a blessing in disguise if you asked him.

The man in a kid's body climbed out of his bed, stretching a bit before rubbing his eyes of any sleep still clinging to him. A moment's decision pushed Ben out of the room, still clad in his pajamas – he couldn't care, it's a Lazy Sunday, might as well relax a bit. He shuffled out of the room towards the kitchen downstairs, shivering running up his spine from the coldness pressing against his bare feet. Instead of finding the sensation annoying on such a morning, Ben found it to be an amazing and thrilling experience – after all, he'd been dead for almost twelve years.

Any sensation was a good one in Ben's book.

The boy made his way into the kitchen seeing Allison and Vanya leaning in close to one another. He smiled to himself, moving to the fridge after telling the girls 'good morning'. Vanya's been doing well with her new training – responding to it better, he corrected – and the friendship building between the two sisters was unbreakable at this point. They have their bouts of arguments every now and then but, by the end of the day, Vanya and Allison have pushed themselves to fix whatever's happening between them.

Ben found it amazing to see his family like this after everyone started to distance themselves from one another.

By the time the boy sat down at the table, a bowl of cereal in front of him, Luther was strolling in. He gave the three at the table a once over before giving a small smile, "Did you all sleep well?"

"I woke up with a crick in my neck but, besides that, I slept alright." Allison shared the smile, looking to her sister, "What about you, Vanya?" Said girl shrugged, looking down at his almost finished oatmeal. She spooned for some more, filling her mouth in order to avoid talking.

Ben furrowed his eyebrows, deep sadness filling his heart. Even though it has almost been two years since the time before, Vanya was still wary of Number One. From what he gathered, Luther exploited her trust before locking her up and has sort-of proven that he was a threat to heKeywordord: was. Vanya's coming around, starting to see him like a brother and not an enemy. She'd been quick to forgive Allison and even faster to forgive Klaus – Vanya hadn't ever held any bad blood for Ben either.

It was Diego and Luther that had become her problem.

Speak of the devil – Diego strolled in, a grin on his baby face. Ben snorted quietly, spooning cereal in his mouth. He stayed silent for the most part – he wasn't sure if it was just in his nature to be non-verbal or maybe it was an aftereffect of being dead for so long.

Luther took a seat at the table, an apple in his hands, "Good morning, Diego."

The other boy slides into a chair beside Ben, propping his legs up on the table, "Yeah, yeah. Dad says we have training in an hour. It's the stairs exercise."

"Well," All heads turn towards Five, having suddenly appeared downstairs with a cup of coffee in his hand, "you all are going to lose. No one's ever been able to beat me at that game."

Allison chuckled behind her hand, "Are you sure that Dad's even going to let you play? I heard that it's Senior Citizen's Day at the local bingo center – that sounds a bit up your alley, don't you think?"

"So, we're playing the age card, huh?" Five sighed heavily, "If that's the case, none of you should be 'playing games'. Aren't you all in your twenties?"

"It's not a game." Luther concluded, self-righteousness filling his voice, "It's an exercise to help re-train us. We all know now that we've lost our skills, so we've got to work again to get back up to that point."

"Yeah, whatever, it's still a game." Allison shook her head, a bit amused. Vanya, for the most part, was staying silent but Ben could tell that she had an underlying bout of excitement filling her eyes.

"Do you remember the first time we ever played that game?" Diego questioned, eyebrow quirked.

"Exercise." The blond-haired boy corrected.

"Whatever." He rolled his eyes, "Five cheated-"

"I adapted, thank you very much." The old man – now boy – hissed out, drowning himself in the last bit of caffeine.

"-and Allison used her rumor to make Luther start making the climb back down to drink the rest of his orange juice." Diego grinned in remembrance.

Luther bristled at that, "Even though I did drink that orange juice, I still managed to get in fifth place."

Five nodded, "Yeah, Klaus looked like he was going to die running up those stairs."

Ben furrowed his eyebrows, glancing towards the stairs at the mention of his brother. The others continued to speak, laughing together with a bit of adult humor sprinkled in there. He stood up from his seat, dumping his empty bowl in the sink before making his way around the table before stopping. "Has anyone seen Klaus?" The boy asked.

Heads turned towards one another before collectively everyone murmured out a quick, "No."

"I'm going to go see where he went off to." Ben hadn't needed to say anything as no one was really listening, his siblings already absorbing themselves in another conversation this time about music. In the back of his mind, Ben hoped that Vanya might contribute towards their discussion.

He climbed the stairs, peeking around corners and in closets. Even though Klaus had promised him that he'd try to stay sober – and he's been doing a damn good job, a year and eight months – Ben sometimes worries that his brother's popping pills again. However, he trusted the boy's promise, and, because of that, Ben would continue to search for him.

The first place he checked was Klaus' bedroom – nothing. The five bathrooms in the house were a no-go too. Ben even checked his own room as his brother was known to stop by and spend an unearthly amount of time there. Still, there was nothing. He moved to see if Klaus was hiding in his siblings' rooms, maybe planning a prank or something – Ben doubted it though. He practically checked every part of the house, but Klaus still evaded him.

He was beginning to worry.

"Ben?"

He turned around, "Mom."

Grace smiled warmly at him, "Are you okay?"

"Just worried a bit," Ben stated, looking at the woman.

"Why's that?"

"I can't find Klaus anywhere." He told the android, "Have you seen him?"

She thought for a moment, eyes flickering, "No, can't say that I have? Have you checked with your father?"

"No. He's busy right now, isn't he?" Ben furrowed his eyebrows in question.

Grace smiled warmly, "Sir Hargreaves is in his study. I could ask him for you, if you'd like?"

"Yes, please." His eyes were pleading. She nodded once before shuffling towards the stairs, disappearing around a corner on the upper levels of their home. Ben didn't waste time though, moving to the library and bar where Pogo was rearranging some books. "Pogo?" He started.

The ape looked startled for a moment, "Master Ben, good afternoon. How can I help you?" He shifted his glasses a bit, setting a book back in its place.

"Have you seen Klaus anywhere?" Ben asked.

He thought for a moment, "Ah, I'm sorry, Master Ben, but I can't say if I had. Last I saw him was last night as he was heading to his room for the night."

"Ben." A sweet voice called from upstairs.

The boy turned around, looking up at the open walkway above him, "Did he say anything, Mom?"

Grace shook her head, "He hasn't seen Klaus anywhere, dear. Is there anything you need?"

"Um… no ma'am, thank you." Ben sighed out, walking back to the kitchen where his siblings still sat together. The only difference was that everyone now seemed to be sporting a cup of coffee like Five. "Guys?"

They glanced up at him, hushed silence running between them all. "What is it, Ben? You look like you've seen a ghost." Diego stated before wincing at his poorly chosen words.

Ben didn't even think twice about it – Klaus has said it too many times for him to find it at all insulting. "Speaking of ghosts… Have anyone of you seen Klaus at all?" He asked, taking a few steps into the kitchen.

"That's what's got your panties in a twist?" Diego snorted, finishing off his coffee, "Klaus used to disappear all the time, it's not all that unusual."

"I wouldn't be surprised if Klaus is on the streets high as a kite." Five shrugged, not bothered by the unusual disappearance of his brother.

Ben could feel the frustration and anger bubbling within him. "Are you serious?!" Everyone stared at him. He hadn't ever once raised his voice at them since he came back from the dead.

Allison rubbed her arm, "Ben, face the facts. Klaus would do anything to smother his fear of the dead and… and that just happens to be drugs."

"Allison's right." Luther stated, "Even if Klaus sobered up for the apocalypse, we can't ever be sure that he wouldn't pick it up again."

"You're all horrible." Ben hissed out, hands balled into tiny fists. He might even have looked terrifying had he been in an adult body. "He hasn't used in almost two years because he promised me he wouldn't." Number Six pointed to himself, hand flat against his chest before pointing at them accusingly, "None of you actually care about Klaus – he's just the junkie of the family to you, isn't he?!"

"Ben…" Allison furrowed her eyebrows sympathetically, however, she couldn't meet the boy's eyes.

"He tries day and night to stay sober, even when he desperately wants to be numb again and that's because he's trying to keep a promise to me." He uncurled his fists, turning around, "And you're wrong – Klaus hasn't been afraid of dead people for a while now."

"Where are you going?!" Luther called out, standing up from his chair.

Ben walked to the door, "I'm going to try to find Klaus."

Luther looked like he might go after the boy but Five simply raised his hand. "You should just quit now before you bother him anymore." He guzzled his drink, "Plus, you can't exactly be mad at him. We've all been pretty critical of Klaus."

Silence filled the family, awkward shifting moving between the remaining five. "Do you think he's okay? Klaus… I mean." Vanya's quiet voice spoke up, eyes running between her brothers and sister.

Allison laid a hand on her back, smoothing out her wrinkled shirt, "I'm sure he's fine."

"Are you sure?" The girl asked her.

No… no one was really sure.
