The evening had been quiet minus a few lousy villains trying to sneak into the treehouse. Thankfully their defense system made sure to alert that someone was on the property and was immediately dealt with. It wasn't too much for one kid to handle himself seeing how all his teammates were in their own respective homes on a school night but he could do without the minor annoyances. Things would quiet down soon but he wanted to be able to update the computer system of some of the newer villains they had fought recently. Even if they had defeated those adults and they weren't a threat at the time there was a good chance they would strike again soon enough so they had to collect as much information on their enemies to ensure another victory by the Kids Next Door. From now on there will be no more distractions.

"DISTRACTION DETECTED!"

Dropping his clipboard in surprise, the boy groaned that it was the phone of all things interrupting him. Not wanting to hear it keep ringing he rolled his chair to the other side of the computer and picked up his phone, telling himself that it had better be important. "Hello?"

"Oh, good! So glad you picked up Nigel, honey!"

"Mom? I told you not to call me unless it was an emergency and besides I'm very busy trying to-"

"You'll consider it an emergency if you don't hurry down here and eat your dinner before it gets cold, young man! We're going to spend some family time together."

The boy knew he wouldn't be able to get out of it. Sure he could refuse and just find something to eat in the treehouse once he was finished with his work but he would be in trouble for not listening when he did finally go downstairs. Hearing that there was a dessert after was enough to convince him to stop his work for now but he would be sure to return once he had been full and satisfied.

"Okay, okay I'll be down in five minutes." He sighed as he began saving the information he had already typed up as he held his handmade phone between his ear and shoulder so he could hear his mother speak.

"Wonderful! We'll wait for you until you come down. Love you, honey!"

"Love you too, Mom," Nigel muttered before hanging up. He sighed as he made sure the defense system would stay on while he left the base of his treehouse. It was highly unlikely that there would be any more unwanted visitors for tonight but he couldn't be too careful. Once everything seemed to be in order, he made his way to the elevator and hit the button for house level.

"Ugh, the things I'll do for cherry pie." He put his head in his hand in slight disbelief at himself as the doors closed.

Like his mother had said his parents had waited for him, welcoming him as he sat down. Nigel said hello to his parents before beginning to tune them halfway out as he focused on his food instead. He picked up a spoonful of mashed potatoes with gravy, making sure to push his asparagus away. No way he was going to let those vile things contaminate the rest of his dinner more than it already had.

His father talked about another fishing trip they could take next weekend and he only got a few bites in before the doorbell rang, setting off an alarm system he had his teammate install. Jumping from his seat, Nigel made his way to the door before one of his parents could get there first. In case it was another adult villain he would be sure to deal with them with one of the weapons he kept hidden in the house. When he did open the door the alarm shut off and he was ready to question what the person wanted but grew confused when a woman he never saw before with long black hair stood at their doorstep.

"Oh! Um, hello young man but are either of your parents home?" She seemed like she didn't expect a kid to answer the door so he could guess that she didn't come here on Kids Next Door business but still raised a brow at her as he answered that they were.

"Nigel ol' boy, don't just stand there. See what the nice lady wants." His dad had left the table to see what was happening, only to find his son glaring at some woman in a pantsuit. He didn't know what he was going to do with that boy.

"Hello sir, are you by any chance a man named Monty Uno?"

"Why, yes I am." He answered and Nigel stepped to the side to observe. "Is there a problem of any kind I can help you with?"

"My name is Patricia Foster. I work for social services and it has come to our attention that you have a long-lost relative in the system that has been orphaned recently and it states that we track down any potential family members to see if they would be willing to take the child in even if temporary or else they will remain in foster care until further notice. No decisions have to be made right away but I have brought the child here with me so you could meet her in person."

Stepping to the side, Patricia showed that there was indeed a child standing behind her who looked up at the man with a sheepish smile as she took one of the hands resting behind her back and gave a little wave.

Both Nigel and his father stood there not saying anything for a moment. Neither one was sure how to properly take the information in. Finally, Monty called for his wife over his shoulder, hoping that she could help address the situation.

"Jen dear, could you please come in here for a moment?"

They were all seated in the living room with Nigel sitting on the couch next to his parents while they looked through some of the paperwork that this Patricia woman was showing them. He tried to sneak glances but his main attention kept going back to the girl sitting on the ottoman on the other side of their coffee table. They were supposed to be related in some way? She had been observing what the adults were doing as well and when she went to move a strand of brown hair behind her ear her eyes suddenly locked with his. Giving a little wave, she mouthed, "Hi" to him, and smiled when he awkwardly waved back.

"As you can see here it says that her dad's second cousin twice removed matched your info." Patricia passed the letter to Monty along with a document of a family tree showing that Nigel's father and this girl did share the same bloodline.

"I guess this is what we get for skipping out on your last few family reunions otherwise we might have already met-." Nigel's mom paused for a moment realizing she didn't catch the child's name and looked to her for an answer.

"My name is Robin. Robin Hughes." The girl answered, biting the inside of her cheek for a moment before speaking again. "So what happens now? Is this where I'll be living or will I have to keep staying in foster care?"

Monty and Jennifer could both hear the nervousness in Robin's voice and looked at each other wondering what on earth they should do. Everything checked out and this girl needed a proper living situation but could they take on another kid out of the blue like this?

"I think if Robin will be more comfortable knowing she's around family then she can have a place here with us. We'll do what we can to make the proper arrangements for this young lass."

"What? Dad don't you think this is all just a little too-" Nigel didn't get a chance to voice his opinion that he felt something was fishy about this whole thing as Robin suddenly jumped up.

"Really? Thank you so much! You don't know how much this means to me! I know this is a lot and I'm sorry to spring all of this on you.." Robin looked to her feet and shifted.

"I can drop Robin here off tomorrow along with the paperwork I will need you to sign claiming to be her new legal guardians." Patricia stood up from the chair and began organizing her copy of the files into her briefcase while Jen took Robin to the kitchen for a moment to get her a slice of pie to take with her.

"Dad, I'm not so sure about this. I'm all for helping out another kid. It's what I do but they don't just show up at your doorstep and suddenly start living with you this fast. At least I don't think they do.." He didn't know how all this was supposed to work but sharing his home with a girl they just met seemed a little weird.

"Nonsense, Nigel ol' bean." His father waved him off. "I know this will take some time to get used to but I'm sure you'll learn to love having a new playmate. You and she appear to be the same age so she'll even be in the same class as you."

"We'll need to make arrangements to have her enrolled in a new school but we'll worry about all of that once Robin has settled in here." Patricia closed her case, having gathered everything, and smoothed out her pants. "It was a pleasure to meet you, folks."

Patricia shook Monty's hand before saying that she was going to warm up the car and just have them send Robin out once she was finished.

Shutting the car door after slipping into the driver's seat, Patricia threw the briefcase in the back before reaching up towards the top of her head. Pulling on her hair it completely slipped off to show that it had been a wig this whole time and her natural red hair was pinned up underneath. Grabbing her phone she quickly began typing a number and spoke once she heard someone answer on the other end.

"Step one has been completed. She's in.."

"So a total stranger is going to be staying in your house?" One of Nigel's best friends, Wally, questioned trying to understand the situation his leader was in even though it had been explained twice already.

"Maybe she will be our friend and I can invite her to my Happy Tea Time Rainbow Monkey Party!" The raven girl, Kuki, giggled to herself not paying attention to the eye roll Wally gave her.

"What did you say her name was again? Raven or something?" Hoagie questioned his friend as they neared the street the treehouse was on. It was after school now and they were walking home while Nigel told them to watch out for this girl when she arrived.

"Her name is Robin. At least that's what she claims to be called." Nigel responded, lifting his sunglasses as they began to slip further down the bridge of his nose. "I just don't get it. Yesterday I was an only child living with my parents and now today I have to share the space with my so-called long-lost- I want to say, Cousin?"

"Maybe you're thinking about this too much Numbuh 1. I mean you have a long-lost cousin on your mom's side and she's a member of the Kids Next Door." The dark-skinned girl of the group, Abigail, reminded him as she twirled a red lollipop between her fingers before putting it back in her mouth.

"Numbuh 10 didn't come to live with me in less than twenty-four hours of meeting her." Numbuh 1 pointed out to his second in command. "Don't you agree it's a little bizarre?"

"Maybe it is but Numbuh 5 thinks you're too tense even more. Ever since that last attack with the Delightful Children you've been a little on edge. I know you went through a lot and it took over a month for us to rebuild the tree house but you need to chill man. If this girl is your cousin and needs a place to crash then as members of the Kids Next Door, Numbuh 5 says we give her a chance and welcome her. She still is just a kid after all."

Numbuh 1 had to admit that Numbuh 5 was right. Maybe he was overthinking this too much. He had been even more suspicious of adults ever since transforming into one himself and having to face their greatest enemy so far. Father. There was no reason to take it out on a fellow kid.

"I suppose you make a good point Numbuh- Hey!"

The four members looked to their leader wondering what caught his attention all of a sudden. They followed his gaze ahead of them to see a car parked in front of his house. She was here already? Numbuh 1 motions for his teammates to follow him as he crept closer and stood on his tiptoes to peer through the side window. The others crowded around him trying to take a look as well. Nigel didn't see any signs of Robin. Only Patricia was sitting with his mom at the kitchen table; talking and laughing with a cup of coffee in each of their hands.

"Hey move it, would ya?!" Wally yelled, jumping to try and gain some height over his taller friends. He tried to elbow Hoagie to the side only for his friend to tell him to watch it and shove him back.

"Would you two knock it off?" Numbuh 1 warned moving the sleeves of Kuki's green sweater from his face while her chin rested atop his bald head, having hopped up on his back so she could get a good view too.

Numbuh 5 stood back with her arms crossed while the other four tried to squeeze around the window. If they kept at it the two women would hear them and see that they were trying to spy on them. Having finished her lollipop, Numbuh 5 pocketed the stick to throw away later when she saw a figure moving toward her friends. "Uh, guys?"

"Can someone just-!" To try and share the space Wally jumped on top of Hoagie but in doing so he made the other boy lose his balance and crash right into the other two, sending them all into a heap on the ground.

"What was that?" Patricia questioned from inside, having heard a noise. Jen only shrugged with a smile before continuing her story.

"Get off me!" Nigel lay face down beneath the weight of his friends trying to lift himself. He was able to prop his elbows when a pair of black shoes came into his field of vision and he looked up to see Robin standing over them with a box in her arms.

"What are you guys doing?"

"Oh! Um-." He began as he felt his teammates move their weights off him. "Nothing?"

Robin raised a brow at him then chuckled before shifting the box to one arm and offering her free hand to help him up. "Good to see you again Nigel." She smiled.

"It's good to see you too Robin." He responded before clearing his throat. "These are my friends." Nigel pointed his arm to the other four behind him. He introduced them each by name along with their respective Numbuhs 2 through 5 as they waved and gave hellos of their own. "And this is Robin. The girl I was telling you guys about."

"Spreading rumors about me already, eh Numbuh 1?" Robin joked using his codename that she learned.

"Ooh! Robin, your hair clips are so pretty! Can I try them on? Please! Please! Please!"

Robin turned to see the bubbly Japanese girl bouncing on her feet. She was the cutest thing but she didn't give in to her request.

"Sorry, Numbuh 3 no can do but thanks. They are pretty, aren't they?" She smiled, hovering her free hand over the clip that was pinned to the left side of her hair. It was merely a gold-colored barrette that mirrored the one on the right. They held importance and no one could wear them but her.

"What's that?" Nigel questioned, nodding towards the box that had 'Robin's Stuff' written on the side.

"Oh! Just the last of my belongings. Your dad is upstairs trying to make sure that the sofa bed still works. They didn't have another actual bed for her to use on such short notice but this would do for now.

"Hey, maybe once you're finished we can all hang out and get ice cream or something?" Numbuh 2 suggested, thinking that his leader was lucky to have such a cute girl staying here.

"I'm lactose intolerant but I'll take on your offer to hang out." Robin smiled, saying that she would be right back before turning and making her way back into the house.

"What does lacruz indolent mean?" Wally questioned out loud, completely mispronouncing the words.

With a sigh, Numbuh 5 corrected that it was lactose intolerant and it meant that she couldn't digest dairy products well which included ice cream. It would make her sick.

"That's a bummer." The blonde mumbled.

"Well, it looks like it's official." Numbuh 1 said as he watched Patricia walk out with Robin, hugging the child before stepping into her car and driving off. Before they had fallen from the window he was able to see some papers with his parents' signatures on them. "Robin is a part of the family now."

-End Transmission-

I don't think we ever learn Mrs. Uno's real name. If it was brought up and I don't remember feel free to correct me but I chose Jennifer cause that's the name of her voice actor. Let me know what you think of the first chapter and I will have the next one out real soon! - Sunbeam
