The Scully-Mulder household was buzzing with excitement as the girls prepared for their high school carnival. Dresses were being laid out, hair products littered the bathroom counter, and music played from Joanna's room as she and Beatrice debated over accessories. Sabrina, however, sat quietly at the kitchen table, her face pale and drawn, cradling her stomach.

Scully noticed immediately as she passed through with a basket of laundry. "Sabrina? You okay?" she asked, her tone shifting from casual to concerned in an instant.

"I think it's just something I ate," Sabrina said weakly, her voice lacking conviction.

Mulder appeared behind Scully, a set of car keys in hand. "What's going on?" he asked, frowning as he took in Sabrina's pained expression.

"She doesn't look good," Scully said, already pressing her hand to Sabrina's forehead. No fever, but something wasn't right. "Where does it hurt?"

Sabrina pointed to her lower right side, her wince deepening.

Scully and Mulder exchanged a quick glance—one of those unspoken moments where years of working and living together allowed them to communicate volumes in a second.

"Sabrina, we're going to the hospital," Scully said firmly, already grabbing her coat.

"What? Mom, it's just a stomach ache—"

"It might be appendicitis," Scully interrupted, her tone gentle but resolute. "We're not taking any chances."

Joanna and Beatrice appeared in the doorway, their carnival plans forgotten as concern for their sister took over. "We'll call the school and let them know we won't make it," Joanna said, her tone unusually serious.

"Girls, stay here and get ready," Mulder said, placing a reassuring hand on Joanna's shoulder. "We'll call as soon as we know anything."

In the emergency room, Sabrina's initial reluctance gave way to quiet fear as the doctors confirmed Scully's suspicion: appendicitis. She would need surgery immediately.

Scully stayed by Sabrina's side as they prepped her for the operating room, her calm demeanor a stark contrast to the worried glances Mulder shot at every nurse and doctor passing by.

"You're going to be fine," Scully assured her daughter, smoothing her hair back gently. "The surgery is routine. I'll be right here when you wake up."

Mulder leaned down, squeezing Sabrina's hand. "You've got this, kiddo. And hey, it's probably better than going to the carnival, right? No scary clowns or overpriced cotton candy."

Sabrina managed a small, weak smile. "I'd rather take my chances with the clowns."

Hours later, the surgery was over, and Sabrina was resting comfortably in a recovery room. The surgeon reassured them that everything had gone smoothly.

Mulder paced the small hospital room while Scully sat beside Sabrina's bed, her hand resting lightly on her daughter's arm. The other girls, having insisted on coming to the hospital, peeked through the door, relieved to see their sister awake.

"Does this mean I get out of chores for a while?" Sabrina mumbled, her voice hoarse but laced with humor.

"Don't push your luck," Scully replied, though the smile tugging at her lips betrayed her relief.

Mulder ruffled Sabrina's hair gently. "You scared us for a bit there, but you're stuck with us. And when you're better, maybe we'll have our own carnival day—just the family."

Sabrina's eyes fluttered closed again, the medication pulling her back to sleep. As she drifted off, Scully leaned back in her chair, her hand still resting protectively on her daughter's arm.

"I think we'll need to stock up on carnival games," Mulder whispered, standing behind her.

Scully smiled up at him, exhaustion and gratitude in her eyes. "I think she'd like that."

For now, though, they were just thankful that their daughter was safe and on the mend.
