Eren stood by the doors as the train chugged along. There were plenty of seats but he didn't care. He was full of adrenaline and anxiousness, he was ready to jump out of those doors as soon as the train stopped. He stood watching the world fly past through the doors, clutching his ticket. When the ticket conductor came round, he shoved it straight under his nose and the man looked at Eren like he was the weirdest person ever. He hurried to the next person as soon as he gave it back to the soggy, panic stricken teen. Eren was out just as the hiss of the doors opening could be heard and he sprinted to the ticket office. When he was in this mood and had this much determination, all of his social awkwardness flew out of the window and he could do anything without a care in the world. This time, he didn't make the same mistake as he had at the other station. He waited in line (impatiently, but he did it) and shifted his weight from foot to foot nervously. When it was his turn he asked the man whether he'd seen Levi. He described him and the situation. The man said he'd bought another ticket from a machine and gone on the next train. Eren thanked him and bought a ticket for the next train. There was a delay and Eren had to anxiously wait for 30 minutes before his train rolled into view. Levi was probably far away now... But that wouldn't stop him. He would chase him to the end of the world if he had to. He dived onto his train. He would find his room-mate, if it was the last thing he did.

Eren followed Levi through at least 7 more stations. He asked each one and they all said that Levi had got on another train or hadn't stopped there. When Eren came to the 8th station, he was beginning to lose hope. He was starving and thirsty as well from so much running and crying. It was about 6:43pm now and it was pitch black as it was winter and the sun set early. He remembered that he didn't have a phone and all his friends would be worried. Mikasa. Oh God, Mikasa... When he found the right station, he'd have to ask to use someone's phone or have to use one of those old telephone boxes. When Eren hopped off the train, he rushed over to an exhausted looking man in a suit, obviously on his way home from work.

"Excuse me sir, but have you seen a man wearing all black stop here? He is about this tall," Eren indicated with his hand to Levi's short 5,3 build, "With black hair and he looks really moody."

"Does he have an undercut and evil looking eyes?"

"Yes! Did he stop here or get another train?"

"He stopped here about an hour ago and left, I've been waiting here for ages because I missed my train by two minutes..." The man huffed. Eren could have screamed.

"Thank you! Thank you so much!" Eren cried out before sprinting to the ticket office. He put his old ticket through the machine to get out and ran out into the street. He was very far away from home but so much closer to Levi. He was freezing cold and he hugged himself, shivering violently in the crisp December air. It had stopped snowing but the air was icy and the wind was cutting. He hoped that Levi was alright and hadn't got hurt or done anything stupid... He looked up and down the dark street nervously. There weren't many people as shops were shut but there was light coming from bright, twinkling Christmas lights and yellow and orange street lamps. He trudged down the street through the snow, his trainers soaked and his feet numb with cold. His hands were blue and his face was going that way too. His hoodie and jeans were soaked through. After a long while, he saw a red telephone box. He prayed that it would work and opened the door, the warm light of a streetlamp coming through the frosty glass windows. He closed the door behind him and looked at the machine. He bit his lip, please say it would work! He knew Mikasa's number even though he hadn't got a phone because she had urged him to learn it in case there was an emergency and he had always thought her stupid... But he was so thankful for it now. He put money into the machine and to his relief, it bleeped and he was able to dial her number. He lifted the phone and it was picked up only about a second after it rang.

"Eren, please say that's you!"

"Yeah, it's me..."

"Where the hell are you? Are you alright?" She sounded so worried.

"Yeah, I'm fine... I'm er... Not going to be back at the college tonight."

"Why not? You'd better be ok and aren't just lying to me, Levi is missing too! I don't know whether I'd rather you were with him or really far away from him! I still don't trust him." Eren went on to explain to her as quickly as he could about the situation, he only had a few minutes on the machine.

"You're WHERE? EREN! That's miles away! And it's late, stop looking for tonight and find somewhere safe to go or I'm going to have to come after you!"

"You can't come after me Mikasa, don't be stupid. And don't act like you're my mother... I'm going to find him, don't worry, I'll be fine."

"But it's dark and freezing!"

"I'll be fine... I've got to go, the machine's about to hang up. I'll try and call you later, I'll call you when I find him too... Bye." Eren put the receiver down before she could say anymore and huffed. He looked through his pockets. He had £31.50 left. He opened the door to the box again and headed out into the freezing street. He was starving, tired and freezing, but he couldn't leave Levi alone. Levi was probably feeling just the same as he was and was probably far less safe right now.

Eren searched the streets for 2 hours until he could physically get no further. He felt he was getting ill from the cold and he was numb all over. He felt quite faint. He flopped onto a snow covered bench and hugged his knees, shaking all over. It was nearly 9pm now and the only sounds were the occasional cars going past and the freezing wind rushing past Eren's sore ears. He lay on the bench by the path beside the road and started to cry. He couldn't go on and he needed to find Levi. He needed help. After about 10 more minutes, a car slowed down at the curb and opened the window. A worried looking brown haired lady wearing a nurses uniform under a brown coat peered out. She was about 25 so was young. "Sweetie? Are you alright?" She called out, watching Eren with a worried frown. Eren peeked over his shuddering knees at her, his face purple from cold and she hurriedly got out of her car and ran over to him. "How old are you? It's freezing, how long have you been out here?"

"S-s-s... s-sixt-t-teen..."

"Bloody hell, you're freezing! You're going to get sick!" She pulled off her coat and wrapped it around Eren's shoulders. "Are you lost or something? Where do you live?" When Eren told her she opened her eyes wide in shock. "What are you doing here then? Come on, come with me boy..." She helped him get to his feet and led him to her car She was just an inch shorter than him. She helped him get into the passenger seat beside her and Eren was too weak too resist. He wanted to stay and look for Levi but couldn't go on. "What's your name sweetheart?"
"E-E...ren..."

"Eren? Well it's nice to meet you Eren, my name's Natalie... I'm going to bring you back to my flat alright? Because you are getting hypothermia it looks like and I'm a nurse, I can look after you." She started the car and as they went she gradually turned the heating up so that Eren didn't get suddenly hit by the warmth. As they went along, she patiently listened as Eren stuttered his story of why he was there and her frown turned more and more grave as he went on. When he'd finished, they were about to park in the car park beside the block of flats she lived in. "That's terrible Eren, you shouldn't be out here alone... I'll help you find him, alright? But I need to make sure you're alright first. Come on, let's get you inside. She locked up her blue car and then helped Eren out. She helped him slowly walk into the flats and they took the lift up to her flat that was on the 5th floor. She unlocked the door and led Eren inside. He trusted this lady, she seemed nice, was a nurse and had offered to help him... He was so worried about Levi. If this was the state he was in, where was Levi? He probably hadn't got shelter and had gone down some alley somewhere. Natalie took him towards the sofa in the small living room and removed her coat from his shoulders. She got blankets and wrapped them around him before going to get him a hot mug of tea. "If I can keep you warm, we may be able to prevent the hypothermia before it gets worse and starts showing symptoms... Hopefully we can stop it before you properly contract it." She said softly as she brought his tea over to him. "You'll have to drink this slowly, it's not too hot, ok?" She put it on the coffee table and sat beside him. "I'll help you find your friend Eren, ok? I'll get you better and then we'll look around the town. Hopefully he hasn't left by bus or anything... If we can't find him in a couple of days, we'll file a missing persons report and try and find him that way, ok?" Eren sniffed as tears trickled down his cheeks and he nodded in silence, unable to speak past the thick lump that was clogging his throat.

Natalie looked after Eren by keeping him warm and making him slowly drink the tea. She got him to eat a few small things and when it was 10:30pm, she told him that he should get some rest now as he was exhausted. She gave him a hot water bottle and left him smothered in blankets on the soft sofa. She turned out the light for him and went to go to bed herself. Eren couldn't sleep for at least 3 hours, he lay crying until there were no more tears to cry. What if Levi was dead? Where was he? Was he sick? Was he safe? Was he alone? Would Eren ever find him? Thoughts whizzed around Eren's head and buzzed in his ears. Eventually, his exhaustion overwhelmed him and he couldn't keep his eyes open any longer, and he fell into a deep sleep...
