It’s Peeta

It's Peeta, his eyes wide and shocked as he takes in the sight of her. Katniss feels a flush of embarrassment, her hands instinctively moving to cover herself.

“Peeta!” she hisses, her voice low and urgent. “What are you doing here?”

Peeta swallows hard, his gaze darting away from her body. “I... I was looking for you,” he stammers, his cheeks flushed. “I heard the river and thought you might be here.”

Katniss narrows her eyes, suspicious. “And you just happened to stumble upon me while I was swimming?”

Peeta looks away, his hands fidgeting nervously. “I... I didn't mean to intrude,” he mumbles, his voice barely above a whisper. “I'll go.”

But Katniss stops him, her hand shooting out to grab his arm. “Wait,” she says, her voice firm. “Don’t go. Stay with me.”

The brunette looks at Peeta, taking in his flushed face and the beads of sweat dotting his brow. She can see the strain in his eyes, the way his body trembles slightly with exertion.

Without hesitation, she reaches out and places a hand on his forehead, feeling the heat radiating off his skin. “Peeta, you're burning up,” she says, her voice filled with concern. “You need to get out of those clothes before you pass out.”

Peeta shakes his head, his hands moving to his chest. “I can't,” he protests weakly. “Not with you like this...”

But Katniss is already moving, grabbing his shirt and yanking it over his head. Peeta gasps, his skin blistering hot to the touch.

“Just shut up and let me help you,” she snaps, her voice sharp with urgency. “I'm not going to let you die out here because of your stupid pride.”

She makes quick work of his pants, pulling them down his legs and tossing them aside. His shirt followed, leaving him in just his underwear, the rest of his body exposed in the harsh sunlight.

Katniss takes a step back, her eyes roaming over his body. She can see the definition of his muscles, the way his chest heaves with each labored breath. But she pushes the thought aside, focusing on the task at hand.

"Come on," she says, grabbing his hand and pulling him towards the river. “We need to get you cooled down before it's too late.”

Peeta stumbles after her, his legs weak and unsteady. But he doesn't resist as she leads him into the water, the cool liquid a shock against his overheated skin.

They sink down into the shallows, the water lapping at their waists. Katniss keeps a firm grip on Peeta, supporting his weight as he leans against her.

“Just breathe,” she murmurs, her hand stroking his damp hair. “Let the water do its job.”
