The triplets sat around the dining table after school, each with an expression of mild discomfort but also a sense of accomplishment. Joanna spoke first, her voice matter-of-fact. "So, it finally happened."

Beatrice nodded. "Yep. First period. All of us. Same day. Guess we really are triplets."

Sabrina chuckled. "Mom's going to say we're overachievers even with this."

When Scully entered the room, she immediately noticed the air of importance surrounding them. "Alright, what's going on?"

Joanna held up a hand. "Before you say anything, Mom—we're fine. You prepared us really well. But…"

Beatrice interjected, "We got our first periods and want to go to the store to check out all the products. There's more out there than what's in that starter kit you gave us."

Sabrina added, "And we want Dad to come too. He should know about this stuff."

Scully paused, her lips twitching in amusement. "Well, I think it's great that you're taking this seriously. Mulder!" she called toward the living room.

Mulder appeared, curious. "What's up?"

The girls turned to him in unison, speaking almost in sync. "We need you to come with us to the store to learn about period stuff."

Mulder blinked, processing, then nodded without hesitation. "Alright. Let's do it. Field trip to the feminine hygiene aisle."

At the store, the five of them stood in front of the expansive display of pads, tampons, and menstrual cups. Mulder looked around, wide-eyed. "Okay, this is… a lot of options."

Sabrina laughed, grabbing a package of pads. "See? You need to know this stuff."

Joanna pointed to the tampons. "And these—some of my friends swear by them, but I'm not sure."

Beatrice tilted her head toward the menstrual cups. "What about these? They're supposed to be good for the environment, right?"

Mulder leaned in, reading the labels with genuine interest. "Okay, so these pads have wings, and these don't. Wings are… what, for extra security?"

Sabrina nodded, holding up a package. "Wings keep it in place better. But they can be annoying if they fold over weird."

Joanna added, "And tampons are for when you want to swim or be more active. But there are different sizes, so you have to choose carefully."

Mulder nodded, furrowing his brow as he examined the boxes. "So these super ones are for heavier days, right? And the regular ones are for lighter days?"

"Exactly!" Beatrice said, impressed. "You're catching on, Dad."

Scully watched the exchange from a few feet away, arms crossed and a bemused smile on her face. "I have to admit, Mulder, you're handling this better than most dads would."

Mulder glanced at her with a smirk. "Hey, if I can investigate aliens, I can handle feminine hygiene products."

Joanna held up a menstrual cup. "What about this? It's reusable, so it's good for the environment. But… it looks kinda complicated."

Mulder read the back of the box and raised an eyebrow. "It does look tricky. I think maybe you'd want to try it when you're older and more comfortable."

Sabrina chimed in, "Yeah, one step at a time. For now, I think I'll stick to pads."

The girls each selected a few different products to try, placing them in the cart while Mulder offered to carry everything.

As they walked to the checkout, Joanna suddenly said, "Thanks for coming with us, Dad. This would've been super awkward if you weren't so cool about it."

Mulder smiled, ruffling her hair. "Hey, it's part of my job. You girls are growing up, and I want to be there for all of it—even this stuff."

Scully, walking beside him, leaned in and whispered, "You know, you're making all parents look bad, Mulder."

He grinned, winking at her. "Just doing my best."

When they got home, the girls happily sorted their purchases, chattering about which products they'd try first. Mulder and Scully shared a quiet moment in the kitchen, watching their daughters.

"You're a good dad, Mulder," Scully said softly, her eyes warm.

Mulder shrugged modestly. "I just want them to feel supported. And hey, I learned a lot today. I should write a field report."

Scully laughed, giving him a playful nudge. "I'll pass on reading that one."

The triplets' laughter echoed from the other room, a sweet reminder of the bond they all shared as a family.
