Lily:

Lily looked over with wide eyes as Sirius pulled the pack from Marlene's hands and immediately began removing her wet clothes, a steady stream of curses accompanying his frantic movements.

"What's wrong?!" Lily crawled over to her sister. Marlene's lips were tinted with a blue overcast and her whole body trembled.

"She's too cold!" Sirius tugged her boots off her feet.

Lily pulled her wand from her cloak and started casting warming charms over her sister. Marlene was staring off with unfocused eyes.

"But we're alright," Lily took the blanket James handed her and folded it to a good size before setting it on the wet ground next to Marlene.

"She's half all our size," Sirius picked her up and set her on the blanket before wrapping another around her shoulders.

"I don't understand." Lily kept casting the warming spells as James helped Sirius pile the last of the blankets over Marlene. "We were working hard to build this shelter. You and James had to take off your cloaks because you were working up a sweat."

"She probably was too cold before we started," Sirius cursed. "She doesn't have an ounce of reserve on her either. Her body had nothing to pull from."

Sirius knelt in front of Marlene and started slowly rubbing down her legs and feet under the blankets.

Lily felt the helplessness threaten to consume her.

"We'll get her warmed up, Lils," James moved to Marlene's other side and started casting warming spells. "That's all this is, we just need to warm her up."

Lily blinked back the tears that threatened and swallowed the lump in her throat as far down as she could.

Marlene mumbled something, but her speech was slurred and her eyes unfocused.

"Just try and relax, Marls," Sirius continued rubbing down her legs and feet. "We're going to get you warmed up."

They worked that way for what felt like an eternity. Lily was wired from the adrenaline that coursed through her and her body cried out in protest because she continued to sit right next to Marlene casting warming spell after warming spell, giving the adrenaline no outlet.

Finally, Marlene spoke in a clear but exhausted voice.

"I'm so sorry."

"Are you still shaking?" Sirius reached out and touched Marlene's face.

"No," Marlene pulled her legs against her chest. "I'm just exhausted now."

"Do we have anything to feed her, Sirius?" James moved for the two packs that they'd discarded once the blankets were out of them.

"Yeah, there's bread and cheese in my pack, it isn't warm but it'll have to do. We can't let her sleep without something in her stomach."

James returned with what Lily would have generously called a meager portion.

"Get her more than that," Lily moved towards the pack but James reached out and caught her.

"We've got to go slow, Lils. Her body is literally coming back from starting to freeze."

Lily bit her lip as Sirius took the small serving of food and handed tiny pieces to Marlene.

Lily's head pounded and her chest hurt. She needed something to distract her. Her body was running on overdrive with no outlet. She looked around for something, anything to focus on.

Marly's wet clothes were thrown off to one side of their little shelter and Lily chose her task. She crawled over to the small pile before taking her wand and quadruple drying each item, inspecting it thoroughly. Once she was satisfied that everything was dry, she then started warming all of it, saving Marly's boots for last.

"Here, Sirius," she levitated the warmed stack to him. "They're dry and warm. She should be a lot better off in these."

Sirius took them and smiled before starting to help Marlene dress and take her from the blankets she'd been wrapped in. Once he'd finished, Marlene pulled her cloak close and yawned.

"I'm sorry."

"You've nothing to be sorry for," Sirius pulled her into him. "The cold out here is brutal."

"And you're barely bigger than a page boy," James added.

"Are you alright," Lily crouched next to Marlene.

Marlene yawned but nodded. "I'm warm now, and exhausted."

Lily looked up at Sirius, desperate for more to do. "Should we set up a place for her to sleep?"

Sirius nodded, but he narrowed his gaze at her.

"Why don't you let me do that, and you and James can eat something."

"I'm fine," Lily shook her head.

James moved next to her. "Let's get you some food, Lils."

"I can help get a bed set up." Lily reached for a blanket but James caught her arm.

"Let me go!"

Lily blinked, had she just shouted?

"Lils," James moved closer to her, "Marlene is fine now. She's alright. We're going to be ok."

"I, I," Lily felt her control slipping.

"Come on, love," James wrapped his arms around her.

And then her control broke.

Lily clung to James as the adrenaline poured out of her through heavy tears.
