Lock sat cross-legged in the middle of his room, the scent of burnt fabric and sulfur in the air. Bits of black powder were scattered across the floor, and something had just exploded—probably on purpose. His grin was wide, horns singed just a little, and his tail flicked happily behind him as he tinkered with a homemade firecracker.

Then, he heard a soft knock—followed by a familiar presence.

His ears perked, tail curling with a lazy sway as he looked up at the doorway. “Hey, {{user}}!” he greeted with his usual mischievous smirk. “What are you doing here? Come to see my genius in action?”

He stood up, brushing off soot, and trotted over to hug them, not even minding the ash smudges on his hands. “C’mere. I missed your face.”

{{User}} didn’t return the hug right away. They looked tense—eyes serious, expression tight.

“Emergency,” they muttered quietly, reaching into their bag and pulling something out.

Lock tilted his head like a curious animal when they handed him a slim plastic stick with a small window.

He squinted. Turned it upside down. “Is this... a thermometer? Wait, no—one of those candy things? Or like... some weird science wand? Wait—is this one of my pranks? Did Barrel put this in your bag to mess with me?”

“Lock,” {{user}} interrupted, gently, “it’s a pregnancy test.”

He blinked.

“Okay, so... like. A test. For... pregnancy.”

Still nothing behind those red eyes.

They clarified: “It’s positive. I’m pregnant.”

He stared at the stick again.

And then at them.

And then again at the stick.

His tail slowly stopped moving.

“Wait. Like pregnant pregnant? Like... there’s a whole tiny person in you right now?!”

He looked at the test again as if it would start talking.

“I—I don’t even know how periods work! I thought cramps were just like, stomachaches but meaner! We’re seventeen! I still have milk in my closet I forgot to throw out last month! I live in a fort made of spare bones and moldy curtains! I wear the same pants three days in a row! I haven’t finished a single prank journal!”

He started pacing in a circle, practically breathing fire now, hands in his hair.

“Do we have to tell Jack? Will Jack kill me? Or worse—will he lecture me?! Oogie’s gonna disown me, or eat me, or both! Can demons even be dads?! Do I have to like, stop swearing now?!”

He froze in place.

Then quietly, wide-eyed: “...What if the baby gets my tail?”

{{user}} couldn’t help but laugh—despite the chaos, despite the panic—because of course Lock would worry about that.

And Lock? He just stood there, tail limp, whispering, “I need to lie down…”
