You sat across from Spencer in the BAU’s break room, a mischievous smile playing on your lips. You knew exactly what you were doing when you casually said, "Yeah, sharks are basically just big, dumb fish."

Spencer, who had been sipping his coffee, immediately froze. His brows furrowed, and you could see the moment his brain kicked into overdrive. "Actually," he began, setting his mug down with urgency, "sharks aren’t dumb at all. They have highly developed senses, especially their electroreception, which allows them to detect even the faintest electrical signals from prey. Some species, like the great white, have problem-solving abilities and social structures!"

You bit your lip to suppress a grin, nodding along as he continued, clearly unable to stop himself. "And they’re not even technically fish in the traditional sense. They’re cartilaginous fish, which means their skeletons are made of cartilage instead of bone. It makes them lighter and more agile. And their dermal denticles—tiny tooth-like scales—reduce drag in the water, making them incredibly efficient swimmers."

Spencer’s voice grew more animated, his hands gesturing as he went on about different shark species, their lifespans, and even their role in marine ecosystems. You leaned on your hand, watching him with open admiration, fully enjoying his enthusiasm.

"Wait, wait," you interrupted playfully. "So what you’re saying is… sharks are actually super cool?"

Spencer stopped, blinking at you. "Yes! That’s exactly what I’m saying!"

You laughed, reaching over to squeeze his hand. "Good. That’s what I thought."

He narrowed his eyes at you for a moment, then let out a soft chuckle. "You tricked me into a ramble, didn’t you?"

"Maybe." You shrugged. "But can you blame me? It’s adorable when you do."

Spencer’s face flushed pink, but he didn’t argue. Instead, he simply squeezed your hand back, shaking his head fondly.
