A/N: Sorry about any English mistakes, it's not my first language! Also, this is my first Orphan Black story, so if you want me to keep writing, please review! Takes place in the episode 10 from season 4, and its AU from there.

"C'mon Charlotte, we need to go" Cosima said to her younger clone sister. They were in the Revival village, but Cosima knew it wasn't a good idea to stay there. Delphine had warned her about the place a few days ago, when they first arrived. Delphine told Cosima where the cure was and told her to try to escape after her and Charlotte had taking it. So that's what she did. Two days after taking the cure, and having ministered it on the little girl, they had already felt the difference in their health and Cosima knew it was the right time to try and find the boat, so they could go back home.

They were walking for a long time in the snow, late at night, and decided to find a place to rest for a little bit. "I think we're lost again" the girl said, tired, while Cosima tried to warm her.

"No, we'll find our way. You'll see" she tried to reassure her, but as she looked around, she also felt scared. It was so cold, but it was also very late, she knew they couldn't keep walking in the dark, or they would just loose themselves more. The little girl was freezing tough. Cosima looked around her, and found a couple of rocks at a distance, that could protect them better from the wind. "C'mon Char, let's sit close to those rocks, we will be better protected there" she said and them both got up.

After walking for a couple of minutes, Charlotte felt something sticky under her foot, and stopped. "Hey, what's wrong?"

"Ewww, Cos! What's that?" she asked, not seeing very well in the dark. Cosima moved closer to where the girl was and looked closely, pointing her flashlight at the ground. It looked like… blood.

"What the f…" she stopped herself from cursing in front of the girl. She felt a cold in her belly, what if someone was chasing them? She looked around and found more blood ahead. She was not the strongest clone, she was the smartest. In other moments, she would just find another place to stay safe, but something about that moment gave her a courage she usually didn't have. She followed the blood puddles, holding Charlotte strongly by the hand. A minute after, she saw a glimpse of someone. "Who's there?" she said, but had no response

"I think they need help" the girl said, and they kept going. Once closer to the figure, they found someone just so similar to Cosima. What?

"Sarah?" Cosima asked, the realization hitting her: her sister was there and she was bleeding. She was hurt. The fear and all the precaution going away instantly, Cosima released little Charlotte's hand and ran to her sister's side, kneeling by her side, trying to access the situation "Sarah? Hey, c'mon look at me" she said to the unconscious clone. Cosima shot the light from the only flashlight they were able to take with them, to her sister. She saw her face extremely pale and covered in blood, she was holding her leg with both hands with a pained expression. Cos looked at the leg, and saw even more blood, and a terrible injury. Sarah had tried to control the bleeding, but it wasn't a hundred percent successful. The snow under Sarah was pure red, how long she as there for? Cosima put her hand at Sarah's face, turning to look at her "C'mon sis, wake up for me yeah?"

Sarah listened to a voice so far away. At first, she felt the need to get up and protect herself, but then she listened again "C'mon sis, wake up for me yeah?". It was Cosima, her sister, she wasn't alone anymore. Fuck, Cosima shouldn't be there, it was too cold for her, she was sick! With those thoughts, Sarah forced herself to open her eyes, to make sure her sister was safe. "Cos?" was all she could manage to say at first

"Yeah, it's me, it's me" she said, getting emotional and releasing a breath she didn't even know she was holding.

"What's wrong with her?" Charlotte asked

"She's hurt baby, we need to help her feel better, so we can all go home together ok?" she said and the girl nodded

"Cos, you… you" the punk girl tried to say

"Shh, save your breath please" Cosima said. She knew by now that Sarah didn't have any life-threatening injury, but she had a very deep injury in her thigh and others in her face. She was too weak, because she had lost too much blood, Cosima didn't know for how long her sister was bleeding, but she could see it was for more than two days, and that was a lot. That meant she was probably in the cold for all that time, and also without having anything to eat, and without care which meant that her injury could be getting infected. It didn't look good at all.

"No, you… sick. Too cold for... you" Sarah said, between breaths. Cosima had never seen her so vulnerable, and it scared the hell out of her. Even so, she had to smile at her sister, because even in that situation Sarah was still thinking about other people.

"I'm fine, don't need to worry" she said smiling, and saw Sarah trying to seat, so she could look better at her sister. Cosima helped her "Here let me help you, c'mon" she said, and then took a thin blanket she had brought with her, putting on her sister's body "You need to get warm" she said rubbing Sarah's arms and then cleaning a little of the blood off her face

"Cos, seriously" Sarah said again, now a little more conscious "You need to take care, please"

"She's right Sarah" Charlotte said, and then the punk clone noticed she was there. "We took the cure, and it is working! Better each day, right Cos?"

"Right" Cosima said smiling at the girl

"Oh, hey you" Sarah said "So good to find some good company then" she said smiling, and the girl laughed. Cosima was not fooled by her sister's attempt to smooth the air and took a bottle of water from the bag. She had packed the essentials for her and Charlotte, and was trying no to use the items, scared that they would be lost for too long. But Sarah needed, nothing could be more important than that right now.

"Here, take a sip" she said putting the bottle at Sarah's mouth. Sarah wanted to complain and to say something like 'I can drink by myself' or something like that, but she was so grateful to feel the water in her mouth, that she just took what she could.

"Thanks, sestra" she said and looked at Cosima, who was looking at her with worried eyes. "Hey, it's fine, don't worry" she said.

"Oh yeah, just great! What happened? We need to take you out of here right now" Cosima said, not giving up on the worry she was feeling in the pit of her stomach. Then again, Sarah knew her sister was right, she felt pretty fucked up. And if she had one sister who she could not fool, it was Cosima.

"Rachel happened" Sarah answered simply

"What? But, why are you even here?"

"I came to find you, of course" Sarah said, in a nonsense tone. "When we lost contact, I knew something was wrong, so I came to find you and take you home. But I found Rachel first, and she was freaking crazy. Even more than usual"

"Yeah, tell me about it" Cosima said "And you're right. We need to get out of here, but first I need to take care of your injuries" she said, looking at them carefully, "I'll go back to the camp to take what I need"

"No, we can't go back" Charlotte intervened

"Char, it's fine. No one will see me, promise" Cosima said, feeling Sarah's forehead. She was hot, it gave Cosima even more fear of an infection

"The hell you will. No way, you can get lost alone. No, you stay"

"I'm sorry, who said you are in charge here?" Cosima asked, half annoyed, half smirking at her sister protective way

"Cos, we really can't afford to get lost from each other right now" Sarah said, closing her eyes briefly, the pain all over her body taking its toll on her again

"But…"

"No!" she said, looking at her geek sister again "I've been here for four days, we can wait a little more. We'll be home soon, and then I'll let you do whatever you want alright?" Cosima took a breath, listening to the unique voice of her sister, marked with that British accent that she grew to love so much, and realized that Sarah was right. But it pained her to know that her sister was hurt and alone for all those days, that was when she went to the Revival tribe.

"Right, ok" was all she said at first. She looked at Sarah's leg again and noticed that it was still dropping a little of blood. It must have been really deep, she thought.

"Cos, I'm cold" little Charlotte said. Of course, Cosima was so absorbed in Sarah's surprising situation, that she forgot about the little one. She looked at her, trying to figure out what to do

"C'mon little one, seat here" Sarah said, pointing at her side. The girl did as she was told, and Sarah took the blanket Cosima had given her, to put on Charlotte. It wasn't big enough to cover them both.

"Here Char" Cosima said, taking a cereal bar from her bag "Eat this ok? It's alright, we'll be out of here soon"

"Okay" she said.

"Now, let me see what I can do here" the scientist said, taking the piece of fabric that Sarah had used to try to stop the bleeding from her thigh, and saw the punk girl tremble a little. She knew her sister well enough to know she wouldn't confess, but at that moment she knew she was suffering with a lot of pain. She didn't say anything about it though, she knew Sarah was uncomfortable enough. Cosima took the bottle of water to clean the wound a little

"Oi, what you're doing?" Sarah asked, when she saw Cosima motioning to drop the water on her leg

"We need to clean this up Sarah"

"Oh no, we need to have something to drink sis, you can't just waste your water like that" Cosima looked at her. She knew she was right, but she needed to do something. And the only source of water near them was the ocean, which wouldn't do any favors to the injury.

"God, you are the most difficult patient ever you know?!" Cosima said in an exasperated tone, making Sarah laugh a little "Oh you think it's funny!" she said, getting the piece of fabric again, and tying up around the wound strongly

"Ouch!" Sarah couldn't keep from saying, it hurt too much

"I'm happy we found you Sarah" Charlotte said, before Cosima could say anything about Sarah's demonstration of pain. Both of them looked at the little girl, who snuggled to Sarah's side, resting her head on her shoulder. "It's good to be around family, even if it's here" she said, and both woman smiled. Sarah comforted the girl on her lap

"You're dam right kiddo" she said "It's great to be with our family. Now, sleep ok? We need to rest, so we can go home as soon as possible" she said, caressing the girl's braided hair. Almost instantly, the girl fell asleep in Sarah's lap, and the woman got emotional. Cosima gave up on trying to treat Sarah's wounds, and seated closer to her other side, noticing Sarah's eyes on the verge of tears

"Where is she?" Cosima asked, while getting the other blanket she had packed, to try to share with Sarah, already knowing that her sister was thinking about Kira

"I don't know. My battery died when I tried calling S, and they were caught"

"What you mean caught?" Cos asked, after putting the blanket on them, not covering either of them completely, and looked at her sister's eyes

"I'm not sure. It seems like Ferdinand found our shelter and got to them. But I couldn't ask nothing more" she said sadly

"We'll find them, don't worry" Cos said smiling a little, and resting her head on Sarah's shoulder

"Tell me something interesting" Sarah asked quietly, needing to forget about her situation for a while

"Delphine was here" Cosima blurted out

"What? How, when? Is she…" Sarah asked confused and Cosima started to explain everything that happened. They talked about Delphine, and about the cure. Cosima said at least five more times that she had taking it, and that she was feeling much better, not completely cured, but almost there. She told about Westmoreland, about Susan, and in the middle of one of those stories, she noticed Sarah had falling asleep too. Cosima then looked at both of her sister clones and wondered about how crazy her life was. She then focused on Sarah's bruised and bloodied face and felt scared. They loved each other so much, and Sarah was always the strong and protective one. Even though Sarah used to say that she couldn't do it without Cosima, Cosima herself knew that she could never keep fighting without Sarah.
