Another request I made for a friend, and another drabble that became into a long one-shot :]

This is a crossover between "Shingeki no Kyojin" and the "Primeval" series. You might don't know too much about "Primeval", but I'm pointing few things related to it, assuring you won't lose in it and have the need to watch the series before to read it (I highly recommend you those series anyway):

I - Eren works for the ARC (Anomaly Research Centre), team of scientists responsibles for investigate about temporal gates called "anomalies". He and his huge squad (the 104) started a journey across time with the objective to investigate about anomalies, but Eren would become in the only survivor with his companion Mikasa, a Victorian lady who joined to the squad during their visit to the Victorian Era.

II - The story is set in the future of the series, which is a post-human era where my favPrimeval predators habit in it3 i was jocking tbh. none can replace the sabre-toothed tiger! I'd called it "Russian Roulette" because I was inspired by Rihanna's song.


Russian Roulette

If there was a time silence calmed him down, now it was the reason of his restlessness.

There was something in the environment that perturbed Eren, but he couldn't describe what it was; he knew something was wrong in that place, as if they approached to a lair of wolves. The abandoned city showed signs it had been habited by humans of the actual era, which Eren and his squad belonged before their journey started, but also showed it had been inhabited for a long time ago.

Maybe for centuries, or maybe for thousand years.

Breathing had become in such a hard task during the last three hours, and things got harder because of the brightness, which were more intense than any other era they'd visited. Eren hardly could see the map which was on the screen of the device he held, which map would take them to any other operational device which could give them the information they needed and, if it was possible, bring the devices to the actual era.

They were explorers of time, responsible for the investigation about the origin of bright gates which broke time and space: the anomalies. Still they hadn't found many things related with anomalies but learnt more about the primeval eras, they had hope in one day they could find an anomaly which could bring them to future eras.

Yet none of them would return home to talk about their journey, but Eren and Mikasa. Five years and twelve different and dangerous eras had been enough to annihilate all the members of the squad.

His companion, Mikasa, followed him with cautious movements, silently, just like every time they entered to a new era. Unlike Eren, who wore a black military uniform, Mikasa wore a different outfit which would be considered by the actual era as "Victorian": a black coat combined by a long and wavy grey skirt, adorned by the red scarf Eren a stormy night gave to her, which lately would be used as a cravat. Inside her skirts long leathered boots would be hidden, and inside her coat, meticulously placed, daggers. Instead of an overloaded rucksack, Mikasa carried a black cross-body bag where she kept her diaries that explained about their journey, personal objects and other weapons.

Mikasa didn't even belong to the squad since the same beginning, but to a well-off family from the Victorian England. Even so, the lady hadn't taken any minute at joining the squad and left the life she had before. Mikasa hadn't been happy, and Eren never dared to know more about her.

"Shall we communicate in sign language?", Mikasa had suggested a while after to explore that post-human city.

"Yes…", he agreed with a nod, and after continued doing slight movements both hands: "It will be the better choice"

Because as always, Mikasa did the better choices. Since forever, Mikasa had been an intelligent woman who always would learn faster than anyone and be the enough cautious when it was needed; the squad had accorded to learn the sign language before to start that mission, because they knew it would be the better for don't be noticed by predators, and Mikasa had took less than two months in communicate perfectly through signs language.

Eren really admired her, since they met.

Suddenly, the device noticed about technologies which worked still, near from they were. Eren felt the warmth feeling of hope in his chest at seeing the intense energy those devices emit, and inside those buildings, if things went well and they didn't find any predator, both could take a rest.

"It has found something.", he announced, once he did an exclamation.

"So can we consider the probability inside those buildings we can find the information we needed to?", Mikasa answered, in whispers.

"Yes, let's go, Mikasa."

"Wait, firstly we have to prepare ourselves with our respective weapons in case any predator appea-…"

And they did: those predators appeared before the lady could finish her sentence, making guttural sounds in their entrance. Raising his head, Eren could descry shapes of skinny and horrible monsters started to descend from the buildings, which Eren recognized instantly and did the attempt to don't scream.

The chiropters were monsters descendants from the tiny actual bats. It had been told by the actual scientists those creatures were the most dangerous to affront, because of the faster and intelligent they were; however, their ears which were placed in their faces were quite sensitive, but unfortunately Eren didn't remember which place of his rucksack he'd kept his grenades.

"Eren", she called him, as she approached to their enemies, "Open the nearest door; I will not take a long period of time in reaching you." She had affronted many predators during the journey, and she had the feeling these would be more difficult to affront.

Though this, Mikasa run towards those creatures holding daggers in both hands, giving him the back before he could retort anything.

She must protect Eren.

"Go!", she yelled.

All his fears and angsts were gone when the battle between Mikasa and those predators started. Mikasa was agile, strong and brave: even with difficulties, she could kill some of the beasts. However, Eren knew she was in danger, and he couldn't use his firearms because there was too much movement: he could shoot her.

"What are you waiting for?! We need a place to be hidden and get information! It is our maxim priority, Eren!"

At first Eren hesitated, but he finally run towards the nearest building and tried to open the door, which was impossible; then, Eren would try again with the front doors of the other nearest buildings, and finally he would hit the doors harshly with his shoulders, most of them many times.

Eren was desperate; Mikasa had become in the woman whom Eren must protect to all costs, because during the journey she would become the one who he fell in love, but he didn't know how to manage his feelings and let her know about them: he'd never felt like that before.

He continued hitting the doors with his shoulders, and then, a door opened: both could be saved! Meanwhile, even all her new bloody wounds, Mikasa continued moving as agile as always she'd been, but Eren knew nothing she did was right: since they met, Mikasa did the most unexpected and dangerous acts only for his own safety.

She never thought about herself! Eren had always hated that fact about her, because she always got hurt by his fault, when the only one who had to be hurt was him for being less cautious or too noisy.

When Eren returned to the fight and saw Mikasa fell to the floor and she couldn't stand up anymore, Eren shot the predators surrounded the injured Mikasa with the firearms he had hidden, and finally snatched Mikasa from those creatures. Once Mikasa was in his arms, Eren run towards the front door of that building the faster he could. Then, he remembered the place he'd hidden his grenades, and decided to launch them to those unpleasant creatures.

With two grenades, the nightmare they were living was finally over.

Eren closed the strong front door of the building before the explosions reached them, and moved away the enough to don't get their ears deaf. He rested Mikasa in the next corner, and after let his eyes got used to darkness the enough to analyse his surroundings: a lonely and dark laboratory, without any other sound than the agonic roars of the chiropters from the outside.

With fast movements, Eren searched in all the places he was sure there would be medicine and products he could use for her wounds. It was his major priority just like every time Mikasa got injured in her great attempts to protect him: heal the wounds of Mikasa, and don't leave her alone for a long time.

Mikasa had her eyes closed when he returned to the place he'd left her, carrying two lab coats. At hearing his steps, she slowly opened her eyes to meet with his glare, which look he'd avoid immediately while he sat beside her.

"Unfortunately, the medicine is expired, so I'll have to elaborate tourniquets in your wounds."

She observed how he cut long strips of fabric with one knife, and without advising at her, Eren elaborate a tourniquet in a scratch of her leg with harsh movements, making her writhe.

"Don't you ever do that again!", Eren shouted, once their glances met again, "You could have died, Mikasa!"

"I had… to do it…", she replied, in gasps.

"Why…? Why do you always have to do these things?", he asked her with a trembling voice, "When will you learn, Mikasa?!"

Eren was suffering because of her, and it really hurt the times he was angry with her or he was upset because of her. Suddenly, she thought about something she could do, in an attempt to calm down and make him finally hers.

"Come… closer…", she asked him in whispers.

He took a moment in obey her petition, and when he did, Mikasa pressed her lips against his. It was unexpected, impressive, even impossible for Eren to be happened, because she'd never shown feelings which he could consider related to love. However, now Eren understood why she always protected him from all the predators had attacked his squad since she joined.

She really loved him.

Eren closed his eyes as he brought her closer, closer than ever, making it longer, the kiss, and forgetting about her wounds, the chiropters, and the inhospitable post-human era they were right then: inside the laboratory there were only Eren and Mikasa, the warmth and desiring moment had arrived, and both didn't want to miss any of their kisses.

Only a moan of pain of Mikasa stopped the kiss, after Eren placed one hand in a wound near to her hip. Eren pulled away and rested Mikasa again, crestfallen with a slight blush in his cheeks.

"Pardon… I had forgotten you were injured"

"It's Okay, Eren…", Mikasa replied, a little ashamed.

Silently, Eren continued elaborating tourniquets in her wounds. It was painful; the wounds had been deeper than both expected, and Mikasa felt herself dizzy because of the pain inflicted in every tourniquet done, as they burned with any contact. But she also felt how Eren tried to be careful, and in his look there was too much worry too.

Once Eren finished, he caught his device and activated the radar of anomalies. When she opened her eyes again, weakly, she saw Eren seemed desperate to be saved, as if he desired to go to another era which was safer for both.

"What are you doing?"

"I want to verify something."

"Eren… We cannot leave… here we can find what we have been searching…", she replied, "Consider your friends… they will have died… in vain…"

Eren furrowed his eyebrow when he heard the lasts words Mikasa said, but he didn't dare to look at her again. He waited impatiently the radar worked correctly, because the battery was about to run out and he feared to stay and be caught in that post-human era without any radar which indicated them their possible and safer departures.

Suddenly, his jaw dropped.

"In this building there's an anomaly that will take us to the actual world!", he exclaimed as he stood up.

"Eren, we must stay here…", suddenly, the tears started to well up from her tired eyes.

"I have a plan, Mikasa.", he said, softer, once he made a bow and caressed her cheek. It had been a long time since the last time Eren saw her crying, when she witnessed the horrible and tragic deaths of Armin and Petra, both attacked and finally devoured by terror birds. Her cry when they found a safe place would be scared and hurtful for anyone who saw her, because both had been such important persons for her. Eren would stay with her the whole night, a stormy night which he discovered the worst of her fears, but he would give her his scarf as well.

Carrying her the most delicately he could, Eren started to seek the anomaly which would bring them to the actual era, where they would be safer. It was a luck Mikasa didn't struggle, but her silent crying destroyed the deepest parts of his being.

The anomaly was in one of the rooms, and Eren did a great trying of be all the cautious he could, because from the darkness nobody knew what could appear. Eren was carrying her, and even if he could hold a weapon, the corridor was too narrow for a fight.

Fortunately, they arrived to the room where the anomaly was, which could bring them to the actual era, to his home. The gate was a circle composed of elements which looked like broken glasses, dancing slowly around the golden and bright nucleus.

It was precious.

In firm steps, Eren went through the anomaly and returned to the actual era. How he could see, the scientists had detected an anomaly, because now they found themselves surrounded by the fellows he left behind the day their journey started. Most of them looked at him and the woman he carried stupefied, but before they could pronounce any word, Eren shouted:

"Block the anomaly! It will bring you to the future, where there are still operative devices!"

"For Lord's… Isn't he Eren Jaeger?", a soldier said as he immediately activated a strange device was in front him.

The nightmare ended. They were already in the safer era, and the anomaly surely would be unblocked weeks later for an expedition to the future era; they surely would question him about the woman who accompanied him, while right then Mikasa had been carried and laid down in a pallet, because Eren had asked for an ambulance as soon as the anomaly got blocked.

In the ambulance, Eren held her hand, tightly, as he wanted to assure her nothing bad would happen and he'd be right beside her until the very end. Mikasa had her eyes closed, in peace, as he kissed their intertwined hands.

The words he wanted to speak to her, and the reports he would give to the military, would be told the most appropriate moment. Both had to recover themselves from that long and exhausting journey.
