This is a short story based on that picture by viria of Pocket/Chibi/etc. Leo.

I do not own Percy Jackson and co, but Louisa is my OC.

Louisa had gone to take Leo his lunchtime coffee. It took her a while to remember where the entrance to Bunker 9 was. Normally, when she opened the entrance, she wasn't greeted with a blinding flash of amber light.

"Leo?" She called, stepping forward tentatively. There wasn't a reply and worry grew for her best friend. "Valdez!" She shouted.

A minute later, she came across the workbench Leo had been working on earlier. Setting the coffee down, she noticed a weird contraption set on a pile of blueprints and notes. She moved to pick it up when a small voice reached her.

"Don't step on me!" (REFERENCE)

Looking down, Louisa started laughing.

"Leo?" She managed, crouching. "Bloody hell, ya four inches tall. What happened?" Leo folded his arms, sulking.

"That thing on the bench. Something backfired and now I'm even more of a midget. Stop laughing!" Louisa carefully picked him up in her hands and she set him gently on the desk, next to the strange invention. Leo gave it a hefty kick before sitting down and sulking further.

"What was it supposed ta be?" She asked, biting her lip to stop herself laughing.

"Um… I'm not sure. One of Archimedes' plans."

"Guys, we've got a problem." Louisa had that look- obviously she had walked in on someone else's misfortune and found it highly amusing. She was holding something in her hands, but they couldn't see what it was.

"Please tell me that's not a spider." Annabeth said stoically.

"No, no, much better." The rest of the Seven and Nico gathered round. Louisa removed a hand and tiny Leo was sat on her palm.

"Aw…" Piper cooed. "Is that an automaton of Leo?"

"No, it's Leo." Their smiles faltered. Percy cracked up laughing, making his sister grin.

"Percy, be nice!" Annabeth ordered, elbowing her boyfriend in the ribs while concealing her own smile. "What happened, Leo?" He muttered something about a stupid machine malfunctioning, refusing to look at them.

Somebody else picked him up and he was suddenly being studied by Jason.

"Don't laugh at me." Leo warned. "I will burn you."

"You'll be about as scary as a candle, Leo." Jason smiled. "And I'll drop you."

"If I die, I'll haunt you."

"Ooh, tiny terror." Nico smirked.

Jason handed Leo back to Louisa on Leo's request.

"We should tell Chiron." Hazel smiled. Frank was staring at Leo bemusedly, carefully not saying a word in case Leo's threat to burn Jason was redirected at him.

"Oh, just tell everyone, why don't you?" Leo grumbled.

"Alright then." Louisa grinned.

"It was sarcasm!" Leo shouted at her. "Don't you even think about it!"

"Too late." Louisa smirked. She casually put Leo in her pocket and walked off to find Chiron. This resulted in another burst of laughter from Percy.
