Eventually came about two years later, when Madi was seven years old.
She had grown up in the valley, so even in the dark, she could run through the trees no problem. Ahead of her, figures with guns - three of them.
She took out one with her spear and shot the other two. The gun - too big for her, really - gave some kickback, but she was able to handle it.
The three with guns had been ambushing a group of people in the clearing, cast in shadows, but they stood back defensively.
"She's just a kid," said one.
Madi stepped out of the shadows and stared - standing in front of her were Clarke's drawings come to life: Monty, Harper, Emori, Echo, and, "Bellamy?"
They stared back.
"Clarke knew you'd come," she said. Bellamy looked older than he had in Clarke's drawings - they all did.
Bellamy spoke first, a slight tremor in his voice. "Clarke's alive?"
Madi was quickly brought back to reality. "And she's in trouble, we have to go."
Bellamy was not quite sure what to make of this kid.
He was making the same calculations in his head that he knew they all were - was he the father? The rover bounced as he drove through the woods, following her directions.
"So what's your name?" he asked.
"Madi," she said. "Take a left here."
"And Clarke is your...?" Harper asked.
"Mom. Clarke is my mom."
Bellamy nodded. "Does anyone else live here?"
"Not till today," she said. "Clarke thought it was you guys on that ship - we don't know who they are."
"We do," Monty said quickly. "They're bad news."
"We're getting close," Madi said, reaching for her gun.
Bellamy stopped the rover in front of Diyoza and her people. "Madi, no," he said. "Monty, get in the driver's seat when I get out. When I signal, drive away, keep the kid safe."
Madi looked like she wanted to protest.
"I promise I won't let anything happen to Clarke."
Clarke blinked in the bright headlights of the rover. "Madi, no," she whispered, but the figure that stepped out was not Madi - much too tall, but familiar.
"I'm unarmed, I just want to talk."
The voice was as familiar as her own name and for a moment Clarke thought she was dreaming.
"Give me one good reason not to kill you where you stand," Diyoza said.
"How about I give you two-hundred and eighty-three." Clarke still could hardly see him, just his silhouette, but there was no doubt in her mind about who it was.
"That's how many of your people are gonna die if you and I can't make a deal."
Diyoza shifted and Bellamy raised his arm, signalling the rover to back away. He knew he should be focusing on Diyoza and the various men with guns, but Clarke was right there.
All the feelings that he had been trying to get over for the past seven years came rushing back - perhaps they had never left.
"Two-hundred and eighty-three lives for one. She must be pretty important to you."
Bellamy looked at her, trying to keep his emotions at bay. "She is."
Clarke was not dreaming, but a part of this still felt not real. Bellamy's arms around her, Murphy and Raven's voices on the radio, it all felt too good to be true.
The bunker was to be opened in the morning, so they had nothing to do for the night. Out of earshot of Diyoza's people, Bellamy sat down beside her.
In the heaviness that settled in the air between them, Clarke knew what was coming next.
"I met Madi," he said.
"Is she alright?"
"She's fine, she's with the others." He stared at the wall in front of them and then glanced back at her. "Clarke, is she -?"
Clarke nodded. "Her full name is Madi Augusta Griffin-Blake."
He smiled. "That's a lot of name for a little kid."
"Say's the guy who named his baby sister Octavia," Clarke said with a smile.
"Does she know?"
She nodded. "Mm-hm. I'm surprised she didn't tell you."
Bellamy was quiet for a moment and then turned to Clarke, a hand on her knee. "You're amazing, you know that? Raising her all on your own."
"Well, she's only seven, she isn't fully raised yet," Clarke said, putting her hand over his. "You're not off the hook yet."
"Good," he said. "I don't want to be."
Clarke smiled and leaned into him. "I'm so glad to have you back."
It was a quiet afternoon - everyone was out and about, exploring the valley, but Bellamy found himself in Clarke and Madi's house. It was cosy and very lived-in.
On the table laid several sketchbooks. Bellamy smiled as he looked through Clarke's drawings - of all their friends and family, of distinct scenes in their past.
That was how Madi knew everything about them.
Not all the drawings were Clarke's thought, many were Madi's as well. He was looking at one - an imagined version of the Ark - when he heard the door open.
He turned to see Madi in the doorway. He smiled and held up the drawing. "So you're an artist too, huh, just like your mom?"
She nodded, coming to stand beside him. "Drawing pictures of her stories made them more real."
"They're really good."
Madi looked at him. "You're just saying that cause you're my dad."
Bellamy shifted awkwardly. "We should probably talk about that." He crouched so they could see eye to eye. "I know you don't know me very well, but -"
"But I do," she interrupted, grabbing one of Clarke's sketchbooks, flipping through it.
"I know about how you and Clarke didn't like each other at first, and about you and Octavia, and 'whatever the heck we want.'"
"And I know about the heart and the head." She looked over at him. "And you're my dad and it's really nice to see you in real life."
She threw her arms around his neck and Bellamy was frozen for a moment before holding her tight.
From the doorway, Clarke smiled at the two of them. Bellamy saw her over Madi's shoulder, and they shared a look; even after so many years apart, they understood each other.
Clarke's heart was close to bursting with happiness. Her only wish in the past few years had been to see them all together - and here it was right before her eyes.
"Lunch is ready," she said finally.
Madi turned and smiled. She grabbed Bellamy's hand, dragging him to the door.
"I've got an idea." Bellamy crouched again. "Piggy-back ride?"
Madi's face exploded into a beaming grin as she clambered onto his back. Bellamy rose carefully and Clarke rolled her eyes at him, smiling. He ducked under the door and took Clarke's hand.
The three of them walked out together.
