I had waited up late last night, anticipating the inevitable conversation with my parents. Luckily for me, both were too busy on the Ark to bother. Part of me was bitter, considering what today was, but I knew the chaos of Bellamy's information stirred up a lot up there.

Luckily, today was Unity Day and Clarke and Bellamy had both agreed to pause work on the camp and defences until after the ceremony. This meant I had a chance to sleep in for the first time since I'd be locked in Skybox.

When my eyes finally fluttered open, I noticed Octavia staring at me from across the tent.

"Were you watching me sleep?" I asked, rubbing my eyes. Then, I smiled. "You're such a weirdo."

Octavia rolled her eyes, standing from her bed and rushing over to mine. "I found something I thought you'd like." She leaned over, rummaging through her pack and pulling out a long knife, handing it to me with a smile. "Happy Birthday."

My eyes widened. "I can't believe you remembered."

"Of course I did!" Octavia beamed. "You made my birthday in Skybox so special, and we weren't even free at the time. I know it's not much, but I figured it would come in handy."

I felt my eyes swell with tears, though I quickly pushed them back. "Thank you, O. I really appreciate you even remembering."

We hugged briefly, Octavia pulling away with excitement. "We are going to have so much fun tonight. Monty is cooking up some of his famous moonshine."

"At least we get to drink it this time."

"I'll let you get ready for the day," Octavia spoke, heading to the entrance of the tent. "Too bad the moonshine isn't ready yet. I could use it to get through the Unity Day Ceremony."

I laughed as Octavia headed out of the tent. After all those years of participating in the ceremony with Clarke and Wells, I could also use a drink.

...

I made my way to the center of camp, finding most had gathered around the monitor to watch the early portion of the ceremony. The camera panned to my father for a moment, a sharp pain shooting through my body. Despite lucking out and getting to avoid talking to him, of course I'd still have to see him.

"Missing being up there for this?"

I turned around, Bellamy appearing. "Definitely not."

He raised an eyebrow. "Kane's daughter doesn't like Unity Day?"

"Kane doesn't like Unity Day." I whispered, earning a chuckle. "It's just such an elaborate show, as if we came together peacefully for the good of mankind. The Ark only became the Ark after the thirteenth station was blasted out of the sky."

"You're even more pessimistic than usual."

I rolled my eyes, turning back to the screen. "You're one to talk."

Bellamy let out a sigh, walking away to join the others.

Alone. As Always.

...

- Six Years Earlier -

I sat on the couch of our family's unit, staring at the door. It was nearing midnight, and I had yet to see my parents all day. When I woke up they'd both been gone, my mother being called away for surgery and my father for whatever 'official business' Jaha needed him for today.

My birthday cake sat in the fridge still, awaiting an adult to stick some candles on it and light it for me. Part of me felt guilty for being upset about missing out on candles; I was one of the lucky few who could even afford to have a cake made. I had read in a book once that cakes were tradition for every birthday on Earth.

The sound of a keycard swipe yanked me from my thoughts as I quickly jumped over the couch. The hard metal door swung open, revealing my mother. She looked exhausted, yet somehow still so put together.

Her eyes finally landed on me, her tired eyes widening. "Honey, I am so sorry."

"It's alright, Mom." I lied. "I spent the night watching movies after the Unity Day Ceremony."

She frowned, placing her keycard on the table by the door. "You shouldn't have to watch movies alone on your birthday."

"I'm used to it." My mother winced, her frown only growing. "I haven't touched the cake yet." I added, smiling.

My mother finally smiled. "Let's bust out the candles then!"

"Really?" I asked. "We aren't supposed to have any flames after ten."

"Are you going to tell Jaha?" She asked. I shook my head. "Good. Neither am I."

My mother marched into the kitchen, grabbing the candles from the drawer as I pulled the cake out of the fridge. She placed twelve candles neatly across the cake, lighting them all with a match. Before I could blow out the candles, she placed a soft kiss on my cheek.

"Happy Birthday, Sweetheart."

My smile filled out my face as I closed my eyes and made my wish. Then, I opened my eyes, blowing out the candles as the clock struck midnight.

...

"My friends, this is a historic Unity Day." Jaha spoke through the monitor. "Every year, we mark the moment our ancestors of the twelve stations joined to form the Ark, but this is the last time we do so while aboard her. Next year, on the ground."

Cheers erupted on the Ark, but most remained silent down here.

"Right. After we did all the work." Miller groaned. "Somebody shut him up."

"You shut up, Miller. Nobody's forcing you to watch." Raven snapped.

"For ninety-seven years, we have eked out an existence, hoping that someday our descendants would return to Earth." Jaha continued.

"Monty strikes again!" Jasper's voice rang out through the camp. "Call this batch 'Unity Juice'. Who's thirsty?"

Many delinquents rushed over, grabbing makeshift cups while Jasper filled them all. I stayed put, for reasons I didn't even understand, watching the ceremony instead.

"To our sons and daughters on Earth listening to this message, we will see you soon." Jaha carried on. "The first Exodus ship will launch in under sixty hours, carrying you the reinforcements that you need, so stay strong. Help is on the way."

As the words filled my ears, I could feel my heart stop. The first Exodus ship meant the second wouldn't be far behind. How soon until my father was down here? Despite the constant threat, I was getting used to having freedom down here. I definitely wasn't ready for him to bark orders at me again. At least my mother would be down here soon. Hopefully before him.

Children carrying flags danced around the screen for a while, a little girl finally stepping into the center of their circle.

"Long ago when the Earth was on fire, through space all alone. Then one day, Mir floated by Shenzhen, and they realized life would be better together." The girl spoke. "The other stations saw this, and they wanted to be together, too. When all the stations were formed, they called themselves-"

A loud bang sounded through the radio, the video cutting to static. We all stared at the screen, waiting for the video to come back, but it never did.

...

The sun had gone down, work came and went, and now it was time to have some much needed and deserved fun. As I walked through camp I watched everyone drinking, laughing, singing and playing games. I'd never seen 'unity' like this on the Ark.

My eyes landed on Bellamy, and I felt a familiar sinking feeling in my stomach. I took a deep breath, marching over until I was standing behind him.

"Hey," I spoke, causing him to turn around. "I was a jerk earlier. I'm sorry."

Bellamy eyed me for a moment, before smiling. "Birthday blues, I get it."

My eyes widened. "How did you-"

"Octavia told me a bit ago." Bellamy cut me off. "I can't blame you for hating Unity Day more than most."

"My birthday was always a little overshadowed." I sighed. "I can't complain too much, though. My mother always found a way to make it special, even if it was just before midnight."

Bellamy smiled. "Your mother sounds great."

"Yeah, she's pretty cool." I smiled back.

I watched Clarke approach us, a frown on her face. "The comms are still dead."

"Best Unity Day ever." Bellamy smirked.

"Now you agree with me." I joked.

"Do you guys really think now is a good time to have a party?" Clarke asked, looking around. "The Grounder is still out there."

I shook my head. "Grounders."

"By now, he's made it home. He's probably putting together a lynch mob." Bellamy spoke, causing Clarke to shift her feet. "Relax. I got security covered. Why don't you go get a drink? You look like you could use one."

"I could use more than one."

"So have more than one," Bellamy responded. "Clarke, the Exodus ship carrying your mother comes down here in two days. After that, the party's over. Have some fun while you still can. You deserve it."

Clarke thought for a moment. "Yeah, okay. So do you, by the way. Both of you."

"I'll have my fun when the Gounders get here." Bellamy smirked.

Clarke smiled, laughing slightly. "Alright."

We both watched her disappear into the crowd, Bellamy spinning the apple in his hand. Finally, he turned to me.

"What about you?" He asked. "Shouldn't you be celebrating?"

I shrugged. "I'm not even sure I know how to celebrate."

Bellamy took one final bite of his apple, tossing it to the side. "Come on." He said, marching away.

"Where are we going?" I asked, my shorter legs struggling to keep up.

"First, we get drinks. Then, I teach you how to celebrate."

I laughed, causing him to stop and look back at me. "You're going to teach me how to celebrate?"

Bellamy smirked. "Trust me, we used to have the best parties on Factory Station."

"Right, I heard about those." I smiled. "I always wished I could go."

"Well, now you pretty much get to."

We reached Jasper, Bellamy asking for drinks. Jasper poured them, eyeing the two of us the entire time.

...

We spent most of the night drinking, talking about our experiences on the Ark and playing different games. Finally, we came across a new group, Clarke among them.

"You're not gonna get this one." Clarke taunted Fox.

Fox smirked. "Yes, I am."

"No, it's not happening."

Fox flipped the metal piece, landing it the cup of moonshine.

Everyone around the table cheered as Clarke admitted defeat, drinking from the cup and spitting the metal piece out.

"What do you know?" A boy spoke. "Her highness can actually party. I like it."

"What are you gonna do when the guards come down here and commandeer Monty's still?" Clarke asked.

"Build another one."

"Right." Clarke laughed, her eyes landing on me. "Athena! Come try."

I shook my head. "I'm alright, thanks."

"Come on, Athena." Bellamy nudged my arm.

I sighed, stepping towards the table. "Alright, what am I supposed to do?"

Clarke explained the rules to me as best as her tipsy self could. I stood across the table from her, aiming my piece of metal towards her cup. I then tossed it, the piece bouncing off the table and landing in her cup.

Clarke stared down at her cup for a moment before looking back up at me with a frown. "I regret asking you to try it."

"Beginners luck." I threw my hands up, smiling.

Clarke and I battled it out for a bit, her getting distracted before we could break the tie. She placed one of the metal pieces on her nose, struggling to balance it.

"Hey, can we talk?" Finn asked, appearing through the crowd and placing his hand on Clarke's arm.

"Is everything alright?" She asked.

Finn looked around before gesturing for her to follow him.

With Clarke gone I stepped away from the table, realising I had sort of abandoned Bellamy. To my surprise he was still there, the smile on his face bigger than I'd ever seen it before.

"You were totally going to win that game."

My eyes widened, my cheeks warming up. "You think so?"

He nodded. "I'm impressed, Athena."

"It's the birthday spirit, I guess." I laughed, stumbling slightly.

"Woah," Bellamy laughed, grabbing my arms. "You alright?"

I nodded. "I'm a little dizzy. Very tired. Too much birthday."

Bellamy laughed again, helping me regain my balance. "Let's get you to bed, alright?"

"That sounds like a good idea."

Bellamy led me across the camp, stopping just outside of my tent.

"Octavia, are you in there?"

No response.

Bellamy pushed the flap to the side, stepping inside and helping me navigate my way through. I quickly sat on my cot, staring up at Bellamy.

"Alright, try to get some sleep." Bellamy's eyes shifted around the tent. "I'll bring you some water in a bit. Drink it when you wake up."

Bellamy turned to leave, but I quickly grabbed his arm. "Bellamy, wait."

He stopped turning back around to face me. I stood from my bed, the alcohol taking over me and I tossed my arms around him.

"Athena?" He asked.

"Thank you, for everything today." I spoke. "It was the best birthday ever."

I felt Bellamy's arms wrap around me, lingering there for just a few moments before we both pulled away. I stared into his soft brown eyes, and he stared back into mine. For a second, I thought he'd say something more.

Instead, he smiled. "Goodnight, Athena. Happy Birthday."

Bellamy turned to exit the tent, pushing the flap aside to reveal Clarke. Her eyes quickly darted to me behind him, before landing back on his face.

"Hey, I needed to talk to you both."

"Been having fun, Princess?" Bellamy smirked.

Clarke glared. "I'm serious."

"You always are."

"Finn's set up a meeting with the Grounders. I'm leaving to go talk to them."

I stood up, my head spinning. "Like hell you are."

"Do you think that impaling people on spears is code for 'let's be friends'? Have you lost your damn mind?"

Clarke rolled her eyes. "Now you two decide to agree on things?"

"Clarke, we have no idea what else these people are capable of. You could be walking into a trap."

"I think it might be worth a shot." Clarke shrugged. "I mean, we do have to find a way to live with them."

"They'll probably gut you, string you up as a warning."

"Well, that's why I'm here." Clarke said. "I need you guys to follow us, be our backup."

"Does Finn know about this?" Bellamy asked.

Clarke shook her head. "He doesn't need to know."

I eyed Clarke for a few moments, before finally letting out a hearty sigh. "Alright, I'm feeling up for an adventure this evening anyways."

"Good," Clarke nodded. "Bring guns."

While I watched Clarke march away, Bellamy turned to me.

"You should stay here."

I shook my head. "No way, I'm coming with you."

"Athena, you were falling over ten minutes ago."

"And now I'm worried about my friends." I snapped. "Bellamy, We've all been drinking. I'll sober up on the walk there."

"Athena-"

"I can't stay behind while my friends meet with the enemy. I'm coming with you, end of discussion."

"No, not 'end of discussion'," Bellamy glared, folding his arms across his chest. "Who knows what kind of danger we're gonna be walking into out there. I know you always feel like you have to risk yourself for your friends, but not this time. I can't worry about you."

I went to protest, his words finally sinking in and forcing me to stop. He was right. As much as I found arguing with him slightly entertaining, I knew this was one battle I would not be winning.

"Alright," I sighed, slapping my hands against my thighs as I sat down on my coat. "Promise you'll be careful?"

Bellamy nodded. "We'll be back before you know it. Try to get some rest."

Bellamy left the tent, and I knew I would not be getting any sleep that night.
