Flynn was tending to his garden of blood blossoms surrounding his home on a floating island in the ghost zone when he saw a ghost floating towards him.

He didn't recognize this one but the ghost didn't seem to be doing too good. It looked as if exhaustion pulled on every fiber of his being as he got closer and closer to him. Once the ghost floated close enough, Flynn picked up his staff and approached.

"You're not welcome here, ghost."

The ghost blinked his eyes slowly, and out of synch, before they opened up wide. He stared at Flynn unmoving for an uncomfortable amount of time, and Flynn was about to try to dismiss the ghost again when he spoke up.

"What's a human doing in the ghost zone?"

His speech was slurred, his arms hanging lazily by his sides and then suddenly, he was falling face first into the ground below him. Flynn stared at the ghost, stunned, and jumped when a bright flash of white appeared around his waist.

Rings traveled up and around his body, and in the place of the ghost was a clearly exhausted teenage boy. Flynn just stared at him, a panic of sorts filling him up.

"What the fuck?" He whispered. This ghost was also human? How was that even possible? Ectoplasm was far too toxic for it to coexist in a human. The only reason Flynn had lasted this long was because his garden fended off some of the ambient ectoplasm.

Flynn was about to pick the boy up and take him inside when he paused. Would the boy be okay inside his hut? It was surrounded by blood blossoms and if the human boy was a ghost, he could only imagine how painful that'd be.

After taking a few moments to think on it, Flynn ran inside and grabbed a blanket, a chair, and his ukulele. He headed back outside and laid the blanket over the sleeping boy and sat down in his chair, strumming his ukulele and humming a song.

If you go down in the woods today, you're sure of a big surprise

If you go down in the woods today, you'd better go in disguise

For every bear that ever there was will gather there for certain

Because today's the day the teddy bears have their picnic.

Flynn spent about half an hour playing and humming along to songs he remembered from his childhood before the boy began to stir. The boy groaned and sat up, holding his head before his back went straight and looked around hurriedly.

He could see the boy look at him from the corner of his eye and was jumping up and turning to face him before halting as he stared at Flynn.

"You're human." He said, lowering his fists that he had raised.

"Yep." Flynn said. "And so are you apparently."

The boy's brows furrowed. "You don't know who I am?"

"No. Am I supposed to?" Flynn lived in the middle of the ghost zone, why would he know who this random kid is?

"I guess not. It's just that all the ghosts knew who I was. I thought maybe someone would've mentioned me to you."

Flynn hooked a thumb back to point at his house. "I don't really want much to do with all the ghosts that live here. Most of them leave me alone but there are some I befriended as a kid. They bring me seeds and stuff so I have food to grow. But I hate most of the ghosts here."

Suddenly, the boy's face brightened and he was hurriedly standing up, throwing the blanket aside.

"I can take you back to the human world! I can help you find your family. There's a family of ghost hunters that live on the other side of a man made portal, the Fenton's, my-"

"Wait, Fenton?"

The boy stopped. "Yeah. Jack and Maddie Fenton. They're self proclaimed ghost experts."

"This Jack Fenton. Is he a big guy with an orange suit?"

Giving Flynn a look, the boy continued slowly. "Yeah. Do you know him?"

"Maybe. My mom used to rib on my aunt's boyfriend when they visited us at home."

The boy's eyes widened. "What was your mom's name?"

"Alicia Walker."

Flynn watched as the boy's eyes widened and he stared into the ground. His hands came up to cover his mouth.

"I always wondered why there were pictures of some random kid at aunt Alicia's house that I'd never met before. I always asked but no one wanted to tell me."

Flynn's brows furrowed. "Who are you?"

The kid looked back up and met his eyes. "Danny Fenton. Your cousin."

Flynn's jaw dropped and he stared at Danny. A moment later another thought struck him.

"Wait, your parents are ghost hunters? And you're some sort of ghost hybrid?"

Danny started waving his hands back and forth in front of him. "They don't know I'm Phantom! So when I bring you home you can't tell them! They can't know."

Flynn nodded. "Okay. You're going to unpack that for me later. But you're going to take me home just like that? You don't even know me."

Danny shrugged. "It's just what I do, I've got a hero complex. Besides, you're family apparently which makes this even more important." He stood up and stretched, transforming back into his ghost form as those white rings appeared once again.

"Are you ready?"

Flynn looked at the staff next to him and the ukulele in his hands.

"Will I ever be able to come back? If I want to?" He asked.

Danny nodded. "I can bring you back any time."

"Okay." Flynn said, grabbing his staff and standing up.

"I'm ready."

QQQQQ

Maddie walked into the kitchen when she heard it. A humming coming from downstairs. It didn't sound like Jack, but it didn't echo like it was a ghost. It must be Danny.

She walked down the stairs and the further down she got the more she realized it didn't sound like Danny. But she did recognize the song. It was the one her mother sang to her and Alicia when they were little, the one she changed the lyrics to and sang to Danny when he was little.

She reached the bottom of the steps, hoping that it would somehow be Jack or Danny, but she was instead met with a young man with red hair and Phantom.

"Spook!" Maddie shouted and she started racing for her gun before she was interrupted by frantic waving coming from Phantom.

"No! You have to call your sister!"

She stared at him confused. "My sister?"

Phantom gestured at the young man beside him who looked at Maddie nervously.

"My name is Flynn. I think you're my aunt."

Maddie stared at him with wide eyes, her gun clattering to the floor. That should be impossible. He shouldn't have been able to survive that long in the ghost zone, especially when he was a child but…

That song. He had Alicia's eyes.

Maddie's eyes filled up with tears as she took him in. "Oh my god." She whispered, covering her mouth.

She walked over, looking up at him. "May I?" She asked.

He nodded.

She threw her arms around her nephew's shoulders and pulled him close to her. Her tears turned into sobs.

"We thought we had lost you. Your mother looked for you for so long."

Maddie pulled away and took a deep breath. "Come on, let's go upstairs and call her. We'll have to fly her out here immediately."

She started walking back up the stairs but turned around before she reached them, meeting Phantom's eyes.

"Thank you, Phantom."

She started heading back up the stairs. Once she reached the kitchen, she picked up the phone on the counter and dialed her sister's number. As it rang, she heard a door open upstairs and Danny's soft mumbling.

"Danny! Come downstairs! I have someone you need to meet."

His footsteps padded into the kitchen behind her and she turned around. He was looking at Flynn with a puzzled expression on his face.

"Hi mom, uh, who's this?"

"Hello, Alicia speaking."

Maddie took a deep breath. "Hi Alicia. I have some very important news for you. We found your son, Flynn."

There was a big pause over the line and Maddie looked up to see Danny's eyes were almost comically wide. She heard Alicia take a deep breath over the line.

"You better not be pulling my leg, Maddie."

Maddie gasped. "Alicia! I would never! Here, Flynn, come say hi to your mother."

She beckoned Flynn over to her and handed him the phone.

He grabbed the phone from her hand and looked at it before slowly bringing it up to his ear.
"Hello?"

Maddie could hear Alicia's muffled voice from where she stood. "Is that really you, Flynn?"
Flynn's eyes widened and filled with tears as he choked up at hearing his mother's voice. "Yeah, mom, it's really me."

A loud sniffle made it's way over the phone. "Dear lord. I thought we'd never find you. I lost all hope. You can bet your butt I'm booking the first flight out of town. I need to see my baby boy."

Flynn chuckled. "Not much of a baby anymore."

"Hush, you'll always be my baby. We've got years to make up for anyways." Alicia said. "Anyways, as much as I'd love to chat I am going to stay by my word and start packing to catch a flight out there. I can't wait a moment longer. I love you."

"I love you too."

When the dial tone sounded through the phone, Flynn handed it back to Maddie. She took it and placed it back on the receiver.

"Danny, why don't you help Flynn find a change of clothes so he can take a shower. I'll work on calling Jazz and your father and letting them know they need to come home."

"Mom do we even have anything that'll fit him? Dad is a brick house and I'm way too short."

Maddie nodded, picking up the phone and punching in the number for Jack's cellphone. "If you rummage around your father's closet there should be a box full of Vlad's clothes from college."

Danny wrinkled his nose at that. "I don't even want to know." He waved a hand at Flynn. "Come on, let's go see what dad stole from the fruitloop."

As the phone rang and the boys headed upstairs, Maddie missed the whispered thank that Flynn gave to Danny and the smile he got back in return. The ringing stopped and she heard Jack's voice on the other end of the line.

"Jack, honey. I have some wonderful news."
