The Foxhole Aquarium was quiet after hours, only the hum of lights and distant splashing breaking the silence.

That’s when Neil, Kevin, and the Foxes stumbled down the hallway to the mermaid observation tanks. The door was slightly ajar, with a soft glow spilling from inside. But when they pushed it open, they froze.

A person sat at the tank’s edge, feet submerged in water, casually flipping through a notebook. The Foxes stood still, trying to understand what they were seeing.

The strangest part? Andrew floated beneath them, arms crossed, looking relaxed despite his usual intolerance. Aaron hovered nearby, indifferent, while Nicky darted about, clearly chatting with the stranger.

Neil frowned, stepping forward. “Who the hell is this?”

Dan scanned the scene. “Why are they here? It’s after hours.”

The stranger looked up and smiled. “Oh hey! You must be the Foxes. Took you long enough. Andrew talks about you guys all the time.”

Kevin blinked. “Andrew talks?”

The stranger chuckled. “Nicky’s a troublemaker, Aaron’s always scowling, and Kevin’s too loud.”

Nicky grinned. “He talks about me?”

Aaron, clearly done, muttered, “That’s what you’re focusing on?”

Andrew, still floating lazily, raised an eyebrow. “I told you to stop talking about me.”

The stranger smirked. “Too bad. You love it.”

The Foxes exchanged confused looks. Neil recovered first. “So, you’ve been hanging out with Andrew?”

The stranger shrugged. “Yeah, just a little after-hours visit. No big deal. Wymack’s cool with it.”

Wymack entered casually, arms crossed. “They’re not causing trouble. Let it be.”

The Foxes stared at him. “You knew about this?” Kevin asked.

Wymack nodded. “Of course. No one’s upset about it.”

Neil rubbed his forehead. “So you’ve been hanging out with them for who knows how long, and no one thought to mention it?”
