(Y/n)'s eyes flew open with a gasp. She looked around and saw she was laying by the train tracks. A few feet away from her, she spotted Prompto who was still unconscious. Pushing her aching body off the ground, she crawled over to him. She gently placed a hand on his arm and called out to him. "Prompto?" She didn't want to shake him in fear of not knowing if he was injured.

After a few minutes, Prompto regained consciousness. He groaned as he sat up. Remembering Noctis had pushed him and (Y/n) off the train, he looked around. "Wh-Where are we...?"

"I...I don't know, Prom. I'm sorry."

Prompto placed his hand over the one she had on his arm. "You don't have to apologize, (Y/n)." He wrapped his hand around her fingers and squeezed them. "I'm just glad I'm not lost and alone."

"Are you hurt?" She asked, eyes raking over his body in search of any severe injuries.

He shook his head. "I'm fine. Just a few scratches and bruises, no biggy. What about you?"

"I'm okay."

The couple stood up, fighting against the pain that wracked their bodies. They both dusted off their clothes before following the tracks in the direction the train went. They trekked for what felt like hours until they arrived at a small hut that seemed to be abandoned. The temperature had dropped significantly and snowflakes began falling from the sky.

To ward off the cold, they entered the abandoned hut. Inside they found the remains of what used to be a small kitchen attached to a living room and bedroom. Some of the furniture still remained while others were missing, leaving only dust particles in their places.

Hearing the chattering of teeth, (Y/n) turned around to face Prompto. "Are you cold?"

He answered with a simple nod, rubbing his gloved hands up and down his arms. She guided him over to the dusty couch, wiping off a space for him to sit on. Turning to the fireplace, she saw there was still firewood inside. Holding out her hand, she ignited the wood. "I'm going to see if there's any blankets around here."

(Y/n) walked over to the large wardrobe near the double bed in the corner of the hut. Opening the doors, she coughed when she was met with a cloud of dust. She fanned the minuscule particles out of her face before searching the wardrobe. She found a single blanket, a pair of fur-lined boots with a matching jacket, and a knit skull cap. She examined the clothing, wondering if they were Prompto's size. Grabbing everything the wardrobe had to offer, she returned to her boyfriend.

"You'll never guess what I found," she smiled at him, squatting down in front of him. Placing the blanket down, she showed him the boots, jacket, and hat. "Think you could wear these? They'll protect you from the cold better than what you're wearing now."

"G-Guess I could try them on..." Prompto said as his teeth chattered once again. He stood up and took off his vest. Picking up the fur-lined jacket, he glanced up at his beloved. "Maybe you should take the jacket, (Y/n)."

Because her element was fire, she didn't have to fear the cold like him. Although her powers were diminished in cold climates, it didn't stop her body temperature from dropping. "I'll be fine, Prom. You'll need it more than I will."

"Oh, right. The whole warm thing..." Prompto switched out his vest for the jacket, then changed his boots. The ones she found were a size too big, but he didn't mind. Finally, he put on the knit skull cap.

Once he was dressed, (Y/n) grabbed the blanket and handed it to him. "You should warm up a little more." She took a step back after he took the blanket from her. "I'm gonna see if there's anything for us to eat."

Before she could turn away from him to head to the kitchen, Prompto twisted the blanket and hooked it around her waist. She gasped as he tugged on the ends of the blanket and pinned her body against his. Their torsos were pressed together, hearts racing in unison. Prompto leant down and rested his forehead against hers. He stared into her gold-slitted eyes before placing a passionate kiss on her lips. The moment she turned her head and opened her mouth, he slipped his tongue inside.

Eventually, they landed on the dusty couch. Prompto pinned (Y/n) beneath him, one hand resting by her head while the other caressed her left side. Once the heated kiss ended and both were panting, the boy wasn't finished just yet. He left a trail of kisses down her jawline and neck, stopping briefly at the crook of her neck. He mentally debated with himself for a few minutes before overruling his hesitation. Latching on to a sensitive patch of skin on her neck, he sucked hard.

(Y/n) gasped at the sensation. It hurt, but gave her a slight tinge of pleasure. She gripped the front of his new jacket. "P-Prompto, what're you doing...?"

He lifted his head from her neck and smiled innocently at her. "What? You've never heard of a hickey before?"

"Of course I have!" She smacked his chest. "Why're you giving me one?!"

"I just felt like it."

She rolled her eyes with a groan. "What a selfish reason..."

His smile widened as he leant back down, nuzzling his nose against hers. "What can I say? You make me selfish."

"Oh, so now it's my fault?"

"A hundred percent!"

All of a sudden, Prompto's joyous smile was overwritten by a sorrowful frown. He stared at the hickey on her neck before trailing his thumb over it. "This is a dream, right?" He asked weakly. "When I wake up, you'll be gone and I'll be all alone. You've been a figment if my imagination this entire time, haven't you?"

(Y/n) frowned melancholically. She grabbed the front of his jacket tighter and overpowered him. She pushed herself off the couch and flipped their positions. Now Prompto was the one underneath her. She stared into his eyes, her expression going stoic. Locating the zipper of the jacket, she unzipped it. Even though he had put it on just a while ago, she was now taking it off him.

With the jacket no longer an obstacle, she reached for the hem of his tank top. Her hands slid underneath the fabric, her warm flesh pressed against his cold abdomen. She gently grazed her nails across his skin before her fingers traced the small hints of muscle across his abdomen. "I'm not a figment of your imagination, Prompto. Nor are you dreaming. I will still be here no matter how many times you open and close your eyes." She removes her hands from underneath his shirt and grabbed one of his hands. She placed it over her racing heart, a gentle smile replacing her stoic expression. "I'm real, and I love you."

Prompto vanquished his dark thoughts. Although he still believed Noctis betrayed him, he was able to push the thought to the back of his mind. When she placed her other hand on his cheek, he leaned into her touch and placed a kiss on the underside of her wrist. "I love you too, (Y/n)." He covered her hand with his and pressed it closer to his cheek. His thumb caressed the top of her hand.

She bent over and placed a chaste kiss on the tip of his nose after seeing the telltale signs of his exhaustion. He was slowly succumbing to sleep and wanted him to rest. "Sleep, Prom. I'll be here when you wake up."

With those reassuring words, Prompto fell fast asleep.

<——————————————<<<<<

Several days later after being pushed off the train, Prompto and (Y/n) had been hiking through the snowy landscape. After an hour, the gentle snowfall turned into a blizzard. The guardian was unfazed by the cold, but the marksman was suffering. His body was starting to be engulfed with frost and he was at high risk of hypothermia. He covered his face with his left arm to protect himself from the blizzard, but it was futile.

(Y/n) stayed as close as possible to him, but not even her warmth could stave off the freezing temperatures of the blizzard. She wrapped her arm around his right one, pressing her body against his. She refused to let him go. He leaned into her warmth, wishing it could've been enough to fought off the chill nipping at his bones and freezing the blood in his veins. "It's freezing out here..." He managed to say before his teeth started chattering.

"I wish I could do more for you," (Y/n) said over the harsh winds of the blizzard.

"You being here is enough," he stated.

"I meant to warm you," she weakly giggled. "Even if I used my powers, it wouldn't provide much warmth. I'm out of my element out here."

Prompto tried to respond, but his body lurched forward. He fell to his knees, taking (Y/n) with him. He gasped painfully, the frigid air burning his lungs. He grabbed the girl's arm and leaned against her body. With her help, he was able to get back to his feet. She supported his weight, but she noticed he was walking slower than before.

"What a way to go," she heard Prompto mumble.

"If you think I'm going to let you die here, you're wrong." She stepped away from Prompto for a second and was about to transform when she heard a 'thump' beside her. Looking down, she saw he collapsed face first into the snow. "Prompto!" She shrieked, kneeling beside him. She noticed his eyes were barely open and he was beginning to lose consciousness.

Through his blurry vision, Prompto could make out (Y/n)'s distraught expression. He could also see two imperial airships heading straight for them. Just as they reached their location, soldiers jump down onto the snowfield from the drop ships above. He watched helplessly as the guardian tried to face off against the adversaries, but one shot her in the neck with a tranquilizer dart. All he heard was her cry of pain and her body collapsing into the snow beside him.

With what little strength he had left, Prompto dragged his body through the snow towards her. His inner thoughts were screaming at him to protect her and so he tried. With a shaky hand, he reached out and grabbed hers. He held it until one of the soldiers hauled her body over his shoulder. He tried to glare at him as he managed to find his voice for a split second. "Let...her...go..." He weakly lifted his head and reached a hand out towards the soldier carrying her. His arm fell into the snow as his vision turned black and his entire world went dark.

Prompto's body reverts to his child years as he walks across the courtyard outside the Citadel with his eyes cast down.

"My whole life, all I ever wanted was friends..." A younger Prompto began.

He looks up to see Gladio, Ignis, and Noctis as adults coming down the steps of the Citadel. They walk past him and across the courtyard, seeming to not even notice him.

"...But no one ever wanted me back."

The young Prompto watches them go, then hangs his head.

"So when I finally found people who did want me, I did everything I could to make them stay."

The young boy lifted his head when he heard the laughter of a girl. In the distance, he saw a little girl four years older than him with (h/c) locks running around while hugging a stuffed chocobo.

"Even with her by my side, I still desperately tried to find other people who wanted me."

Young Prompto starts to run after his friends and the little girl, but they vanish. He hangs his head once more and turns to walk back towards the Citadel steps.

"And ever since then, I've lived my life in fear..."

The little boy sits down on the steps.

"...That, one day, they'd find out who I really was, and they wouldn't want me anymore. Once knowing truth, even she would leave me."

Young Prompto looks up as his mind fills with his memories from his journey with Noctis, Gladio, Ignis, and (Y/n). The one memory that plagued his mind the most was of his best friend attacking him and (Y/n) atop the train before falling.

•••••

Prompto awakens laying face down on the floor in a research lab. He grunts, looks around him, and slowly gets up onto one knee. Looking down at his right wrist, he realizes the bracelets he wore to hide the barcode on the back of his wrist were missing. His eyes widen in horror at the sight of the missing accessories. "They're gone. Where's (Y/n)'s gemstone?"

He searched his pockets and couldn't find a single bracelet. He looked around the room again and noticed he was alone. Getting to his feet, his eyes scanned the room once again. "What... What is this place?" As he remembered what happened to the girl, he shouted her name. "(Y/n)?!"

Locating a control panel beside metal doors, Prompto rushes over and lays his right hand on the panel. An automated voice begins speaking, startling the marksman. "Scanning production code." He gasps and looks around him, taking a step back as the automated voice continues. "Unit 05953234 confirmed."

The metal doors before him slide open. Prompto looks down at his barcode as the computerized voice speaks once more. "Warning: this unit has been compromised. Initiating retrieval of compromised unit."

"What's going on?" Prompto muttered in fear.

Suddenly, Ardyn's voice mockingly chimes in from behind him. "She still remembers you, after all these years."

Prompto turns to face him. "You..." He tries to conjure his weapon, but nothing appears. He looks down at his hand with a puzzled expression. "What gives?"

As Ardyn walks toward Prompto, he pulls out the confused younger man's gun and waves it aloft. "We can't have you spilling blood here." The boy takes a step back as the chancellor reveals what else he was holding. It was the bracelet with the golden gemstone. Prompto's eyes widen at seeing the accessory in the man's possession. Smirking, Ardyn dangled the bracelet in the air haphazardly. "Although to most this compound is known only as the First Magitek Production Facility, birthplace of the myriad magitek troopers and daemons the empire holds dear, to you and that darling guardian this place should have some sentimental value. After all, it is both your home sweet home."

Prompto's expression becomes intense. "Shut up," he growled.

"I'm not the one who almost killed you," the chancellor remarked, twirling the bracelet around his index finger.

"You're wro—"

Ardyn lets Prompto's gun turn upside down over his finger and shoves its handle against the boy's chest. Prompto reaches up to grab it and the auburn-haired man releases it for him to take. Ardyn then takes a step back with the bracelet still in his possession. "You really ought to take a rest." He took a few steps back. "Perhaps the estimable Chief Besithia will help heal that broken heart of yours."

Prompto's glare sharpened. "Who the hell is that?"

"Oh, how quickly they forget. But fear not: I've no doubt a reunion would refresh your memory. Your precious (Y/n) may also shine some light on the situation for her memories of this place are quite vivid."

Ardyn turns and begins walking away. Prompto raises his gun and points it at the chancellor's back. "Wait!" He shouted, causing the man to stop and turn back around. Prompto gripped the pistol tighter, ready to pull the trigger. "Give that back!"

The chancellor glanced at the bracelet in his possession before smiling eerily at the blonde. "Why, this doesn't belong to you, dear boy. You may be one and the same, but this bracelet belongs to another."

Prompto's hands shook, his aim becoming unsteady. "What're you talking about?!"

"My, my. She hasn't told you?" With a mocking smile, he waved the bracelet around. "A shame, really, but all your questions will soon be answered. Ta-ta, dear boy."

Just as Prompto was about to pull the trigger, the chancellor walks away and seemingly vanishes into thin air. He lowers his gun with a frustrated expression. Holstering the firearm, he looks around the room one last time with determination. "I'm gonna find 'em—wherever they are. I'll get that bracelet back and find (Y/n). We'll get the hell outta here together." With those final words, Prompto leaves the room.
