I apologise for any misspellings of Chantelle if you see Chanelle its meant to be Chantelle

Detective Erin Lindsay and Detective Jay Halstead strolled into the bustling precinct, their laughter echoing off the walls. Their playful banter and subtle flirting drew amused glances from their colleagues. Voight, the stern-faced sergeant, noticed their entrance and beckoned Jay over.

Erin started to follow, but Voight intercepted her. "Hold on, Lindsay," he said gruffly. "I need to talk to Halstead."

Erin nodded, curiosity piqued. She walked to her desk, where the rest of the unit was huddled, whispering quietly. Ruzek, the youngest detective, leaned in. "You won't believe it," he said. "Mouse is gone."

Erin's eyes widened. "What? Are you serious?"

The others nodded, and just then, they heard Jay's voice—loud, desperate—coming from Voight's office. "No, damn it! I won't let him go!"

Erin's heart clenched. She rushed toward the closed door, but Voight stepped out, his expression grave. "Lindsay," he said softly, "Jay's hurting. He needs you."

Erin pushed past him, her pulse racing. Inside, Jay sat on the edge of Voight's desk, tears streaming down his face. He looked up as Erin entered, and without hesitation, she crossed the room and pulled him into her arms.

Voight watched from the doorway, a rare tenderness in his eyes. "Take care of him, Lindsay," he murmured. "We've got your back."

And so, in that chaotic precinct, surrounded by colleagues who were like family, Erin held Jay tightly, promising silently that she'd never let him go either.

Erin gently guided Jay to the truck, his steps unsteady. She buckled him in, her touch reassuring.

The drive to their apartment was silent, the weight of the day hanging heavy between them. When they arrived, Erin helped Jay out of the truck, supporting him as they climbed the stairs.

Inside, she eased him onto the bed, his exhaustion palpable.

Jay's eyes met hers, gratitude and pain mingling. "Thanks, Erin," he whispered.

She smiled softly. "Rest now. I'll go pick up Chantelle."

Erin retrieved Jay's jacket and shoes, placing them neatly by the door. She leaned down, pressing a gentle kiss to his forehead. "I'll be back soon."

As she stepped out, the promise of returning hung in the air—a lifeline for them both. Erin navigated the familiar streets, her heart heavy with worry.

Erin approached Chantelle's school, the familiar brick facade welcoming her.

She spotted Miss Adams, Chantelle's teacher, standing near the entrance. Erin's heart raced; she knew she had to break the news gently.

"Miss Adams," Erin began, her voice steady, "I'm here for Chantelle. Jay… he's not feeling well today."

Miss Adams frowned. "But Jay always picks her up. Is everything okay?"

Erin hesitated, then nodded. "He's resting. I'll take care of it today."

Miss Adams studied her, concern etching her features. "Tell Jay we hope he feels better soon."

Erin managed a small smile. "I will. Thank you."

As she walked down the hallway to Chanelle's classroom, Erin carried the weight of Jay's pain. But she'd shield Chanelle from it, just as she always did.

Erin smiled down at Chanelle, her heart swelling with love. The little girl handed over her backpack, her eyes wide and curious. "Mama," she said, her voice soft,

"Where's Daddy?"

Erin knelt down, brushing a strand of hair from Chanelle's forehead. "Daddy's not feeling well today, sweetheart," she explained gently. "But he'll be okay. We're taking care of him."

Chanelle nodded, accepting the answer. Erin scooped her up, holding her close.

Erin and Chanelle hurried over to Jay, their concern etched on their faces. But Jay pushed Erin away, his eyes haunted. The pain radiating from him was palpable, and Erin's heart clenched.

"Jay," she whispered, her voice breaking, "you don't have to carry this alone."

He shook his head, his vulnerability laid bare. "I can't lose him, Erin. Not like this."

Erin glanced at Chanelle, who watched them with wide eyes. "We won't," she promised, her grip on Jay unwavering. "We're family, remember? We'll fight for him."

Jay's desperation hung heavy in the air. He snatched up his jacket and the half-empty beer bottle, his eyes wild. Erin's heart raced as she stepped in his path.

"Jay, where are you going?" she demanded, her voice sharp.

He glared at her, his pain etched across his face. "Anywhere but here," he spat. "I can't stay."

Erin's frustration boiled over. "You think running away will solve anything? We're a team, Jay!"

He scoffed. "Team? This isn't a damn game, Erin."

Before she could respond, he stormed out, slamming the door behind him. Chanelle, wide-eyed, tugged at Erin's hand. "Why's Daddy so mad?"

Erin knelt down, gathering her daughter close. "Sometimes grown-ups get lost, sweetheart," she whispered. "But we'll find him. We always do."

Five hours had slipped by since Jay stormed out, leaving Erin with a knot of worry in her chest.

She paced the living room, glancing at the clock, her mind racing through worst-case scenarios. Chanelle sat on the couch, her eyes wide and innocent.

"Where's dada?" Chanelle asked, her little voice filled with longing. "I need him to read me a bedtime story with the voices."

Erin knelt down, gathering her daughter into her arms. "I know, sweetheart," she whispered. "We'll find him. And when we do, he'll read you that story, complete with all the voices—just like he always does."

The unit huddled around the takeout pizza boxes, their laughter forced. Hours had passed, and still no sign of Jay. When the door swung open, they all turned, expecting relief—but what stumbled in was a stranger.

Jay's eyes were bloodshot, his clothes disheveled. He reeked of alcohol, and his usual charm was replaced by a raw desperation. The unit exchanged shocked glances, their concern palpable.

"Jay," Erin's voice cracked, "what the hell happened?"

He brushed past her, muttering, "Shut up, Erin." His steps wavered as he headed for the kitchen.

But Erin wasn't one to back down. "You can't just—"

Jay snapped, "I said shut up!" His anger ricocheted off the walls, and the unit winced.

Voight stepped forward. "Halstead, we're—"

Jay cut him off. "All of you, just leave me alone!" He stormed out, the door slamming behind him.

Before anyone could react, Chanelle's voice echoed from her room. "Dada?"

They froze. Jay hesitated, then turned toward her. But instead of tenderness, he shouted, "Not now, Chanelle!" And he was gone.

Chanelle clutched her stuffed bunny, tears streaming down her face. The unit rushed to her side, their own hearts breaking.

The clock struck midnight, casting elongated shadows across the apartment. Erin paced, her worry gnawing at her insides. The unit exchanged glances, their concern mirrored in furrowed brows and tired eyes.

"You think he'll come back?" Ruzek whispered.

Erin's voice cracked. "You didn't see him, Ruzek. He's unraveling. I'm scared he's turning into Pat."

Voight stepped forward. "We'll find him, Erin."

But just then, Jay burst through the door, his face twisted with anger. "Enough!" he snapped. "I can't stay here."

Erin squared her shoulders. "Jay—"

He cut her off. "Don't pretend you know what I'm going through!" And with that, he stormed out into the night.
