Hello! I love headcanons! So decided to write a series of One-Shots for them! These ones will probably be longer than any of my Sneefee One-Shots, so be prepared. This first one is based on Leo, of course.

Audience: *sing-song* Obsessed...

*growls* Whatever. One-Shots rated K to T. This one is K+.

Disclaimer: I dun own 'em. End of story.

Leo is a really, really good liar. Unless he's talking to his family, since his conscience makes him really uncomfortable if he tries. He usually only lies to his enemies.

9-year-old Leo gasped as his katana flew from his hand and landed in the straight middle of Splinter's shelf with his prized possessions. The shelf collapsed after a second, and Leo ran over. He picked the stuff up and stood it up, then gasped again as he realized one of the Drauma dolls was split in half.

"Oh, no... Sensei's gonna kill me!" he muttered to himself, putting the pieces together as if it would magically fix.

He put everything the way it went, except on the floor, and strolled out, taking out his katana from the wall and erasing all evidence that he was there.

A few hours later, when Leo was watching Space Heroes, Splinter's voice rang out from the dojo. "BUYS! GET IN HERE!"

Leo and his brothers immediately dashed to the dojo, kneeling in front of their pissed teacher. "What happened here?!" the rat demanded, pointing to the broken shelf.

Leo tapped the dojo floor.

Raph and Donnie immediately looked at Mikey, who waved his hands in front of his face. "No way! I'm not that stupid! Even I would've told Splinter!"

Raph crossed his arms and rolled his eyes. "Yeah, just like when you 'told him' how you nearly burned down the kitchen by somehow managing to set the REFRIGERATOR on fire."

"And the time that you got high off something in the sewers," Donnie added.

Splinter noted this detail.

Leo scooted backwards, and Splinter peered at him. "My son, do you know anything about this?" he asked calmly.

Leo shook his head. "Nope. No idea."

HA! You're lying to your own family!

Leo mentally kicked himself.

Splinter stroked his beard. "Are you sure?"

Leo smiled a wide, crud-eating smile with his eyes scrunched closed. "Nope."

Splinter nodded. "Very well."

Leo's smile faded, and his conscience started eating at him. "Um, actually, Sensei? My, uh, my katana accidentally flew out of my hand, and hit the shelf. Gomen'nasai. (Sorry)"

Splinter nodded again. "Thank you for telling me, Leonardo. Though you will be punished for not telling me and then lying. No TV for a week."

Leo bowed. "Yes, Master."

"Dismissed."

All of the Turtles left the dojo, except Leo came back with Gorilla Glue. "Please forgive me, Father."

Splinter smiled warmly and the duo fixed the shelf and the Drauma doll.

6 years later, during a mission...

"Where have those known as the turtles hidden that which is known as the Power cell that powers the portal that is known as the portal?" a Kraang asked, shooting a laser at the team, his comrades doing the same.

Leo pretended to act worried. "Um, in the warehouse. I swear."

The Kraang nodded, and Mikey threw a smoke-bomb, covering their escape.

On a nearby rooftop, Raph patted Leo in the carapace. "Man, buddy. I thought you didn't know how to lie! I mean, after you broke Sensei's stuff..."

Leo sighed at the memory, the missing eye on the Drauma he'd broken a constant reminder. "Well, my conscience doesn't eat away at me when I lie to enemies, so..."

Raph chuckled. "OK, buddy."

OMG, awful ending! Sorry! Please don't hate me! Well, how'd you like my first headcanon? OK? Or no? Review, rant, flame, check out my community, and vote on my poll! And try to find out who the guest reviewer is that's posting story chapters in my Sneefee Hugs story is! It's so weird! BYE!
