Volume 1 Part 2 Chapter 4
The Dinosaur Visit
Cooposaurus stood outside Renji’s cabin one afternoon, head tilted, ears perked, holding an entire bundle of cardboard tubes clutched proudly in his mouth—rescued from the recycling bin like priceless artifacts. His shadow swallowed half the wall. His tail knocked loose leaves from the roof.
Renji squinted from his bed. “…Wow,” he murmured. “You’re… big .”
From the small table beside the bed, someone snorted softly.
“You said that yesterday too,” Mira said, without looking up from the mug she was setting down.
Renji turned his head, startled—then smiled, tired but genuine. “Did I?”
“Yes,” she said. “Right before you fell back asleep.”
Coop sniffed at the door. Whined softly.
Renji pushed himself up on one elbow, blinking at Coop. “Okay. First of all—when did you turn into a dinosaur? Because I feel like that’s a conversation I missed.”
Mira shifted closer to the wall instinctively. “I’m assuming he’s… friendly?”
“Oh, absolutely,” Renji said. “Enthusiastic. Spatially unaware. Emotionally generous.”
Coop shifted his weight.
Then, deciding doors were suggestions, Coop took one enthusiastic step forward.
The cabin wall did not survive.
Wood splintered. Dust flew. Mira yelped and jumped back as Coop burst through the side of the structure like a furry avalanche, tail wagging, cardboard tubes launching in all directions. He scrambled forward, tangled briefly in his own feet, then flopped—full body—onto the bed.
Directly on top of Renji.
The mattress protested. Renji wheezed.
“—Coop—” Renji croaked, laughter breaking through the shock. “Buddy. Friend. You can’t just—oh wow—you’re heavy now.”
“Do I need to—?” Mira started.
“No,” Renji gasped. “No, this is… this is happening.”
Coop responded by wagging harder, snorting happily, and immediately chewing a cardboard tube directly over Renji’s chest. Shreds rained down like festive confetti. One tube escaped and rolled under the bed.
Coop noticed.
Coop attempted to retrieve it with his entire torso.
Renji coughed, half-laughing, one hand sinking weakly into thick fur. “Okay. Okay. I get it. You brought me presents. Again. Where—seriously—where do these even keep coming from?”
Crunch. Rip.
“…Is there a secret cardboard dimension?” Renji added. “Because I’m starting to feel like I should be charging rent.”
Mira watched, equal parts alarmed and amused. “He’s been doing this every day,” she said. “I thought maybe it was enrichment.”
“It’s love,” Renji said. “Aggressive, structural love.”
The weight was absurd. Comforting and overwhelming.
Renji didn’t push him off.
He just lay there, breath slowly evening out, listening to Coop’s contented rumble and the ridiculous, soothing crunch of cardboard. His fingers flexed weakly against fur that felt warmer than it used to.
“…You know,” Renji said softly, staring at the ruined wall, “most places would have noticed this by now. The size thing. The wall thing. The you being a dinosaur thing.”
Coop chewed.
“I mean, I give tours,” Renji went on. “People notice when the brochures are crooked. But you?” He huffed a tired laugh. “You turn into Cooposaurus Rex and everyone just… keeps walking.”
Coop’s tail thumped once, powerful enough to shake the bed.
Renji smiled despite himself. “Yeah. That’s what I thought.”
Mira glanced toward the window.
Fin perched there silently, wings folded tight against his sides. Thin. Bat-like. Too large for his small body. His eyes stayed fixed on Renji.
“…Renji,” she said carefully. “Was he always like that?”
Renji followed her gaze. He paused.
“No,” he said. Then, gentler: “But he’s still Fin.”
Mira nodded, accepting that as the whole answer.
The days blurred after that.
Renji slept. Woke. Slept again.
Mira came and went quietly, bringing water, soup, clean sheets. Sometimes she talked. Sometimes she didn’t. Coop visited often, never learning his size, never arriving without more cardboard offerings—tubes, boxes, an entire flattened crate once that barely fit through the hole in the wall. Each visit ended the same way: too much weight, too much warmth, and Renji laughing until it hurt.
Sometimes Fin perched on the windowsill, watching silently, wings tucked tight. Renji noticed the change without comment—just a quiet acknowledgment that more had happened while he’d been asleep than he’d realized.
Slowly, almost imperceptibly, Renji’s hair began to change.
At first it was just a streak at the temples—so pale it looked like sunlight catching wrong. Then more followed. Each morning, a little more white threaded through the blonde, as if whatever had passed through him was rewriting him strand by strand.
By the time he was well enough to sit up without dizziness, his hair was almost entirely white.
By the time he could stand, it was completely so.
Renji caught his reflection once and blinked at it.
“…Huh,” he said.
Mira leaned in the doorway. “Does it hurt?”
“No,” he said after a moment. “Just feels… like I went somewhere.”
She watched him, then nodded. “Okay.”
Coop wagged.
And somewhere beneath the Sanctuary, the Engine continued to glow.
