One second they were having movie night. And the next second they were on their feet, circling a much larger mutant turtle who had just dropped directly into the center of their home's pit.

"Uh, Leo?" Mikey's nunchucks were swinging, but he wasn't making any moves to strike as he stared with wider than normal eyes at the intruder. The intruder whose blue mask and blue eyes made him look an awful lot like his eldest brother. The katana strapped to his shell were a pretty big clue too.

"Leo?" Raph growled. The muscles in his arms strained to make a move. He was only willing to wait for Leo to give an order for a few more moments. This new turtle had at least a foot on them in height, and the muscle mass to go with all those extra inches.

Leo watched as the intruder turtle's hands twitched, a move Leo recognized, since his hands did the same thing anytime instinct told him to pull his swords. But this turtle didn't pull the weapons, so Leo shook his head slightly, an order he knew both Raph and Mikey were waiting for. He heard Raph huff out a breath in disagreement, but his brother obeyed anyway, and took a step back away from the stranger, as did Mikey.

The new turtle sensed the shift in intentions and turned his shell to the other two in order to face the leader turtle. He frowned as he stared down at –

"Leo?" He phrased it as a question, although he wasn't really asking. He was clearly in a sewer lair and the blue masked, blue-eyed turtle had to be Leonardo.

"Who are you?" Leo asked, fierce mask in place, although the blue eyes he was locked onto were beginning to look amused.

"I'm Leonardo. I'm you. Well," he paused and his hand rose above Leo's head, indicating the vast difference in their height, "I'm sort of you."

Leo glared at Mikey when he heard him snicker before turning back to Leonardo. "How can that be? How can we trust that?"

Leonardo kept his eyes focused on Leo. Instinctually, he knew that if he could get Leo to believe him, his ability to get home would go a lot smoother, especially if this group had a spare Donatello around. Plus, if Leo trusted him, then maybe Raph would put away the sais he was still gripping tightly in Leonardo's peripheral.

Leonardo held up one finger, "I'm the leader of my three younger brothers." Leo didn't look impressed. He lifted a second finger, "My father is a mutant rat named Master Splinter."

Leo tilted his unimpressed head. So far that was all common knowledge among anyone who knew they existed.

Leonardo pressed his lips together. He liked his privacy, and would bet money that this Leo did as well. But if the guy wasn't going to believe him, then he really had no choice.

A third and final finger was raised. "And I hoard dark chocolate like there's no tomorrow in a spare set of sheaths I keep hanging on the wall in my room."

"Hey!" Leo hoped both Leonardo and Mikey realized the shout was for both of them. One for ruining the best hiding place he had in the entire lair. And the other because he'd already taken off for Leo's room.

"You've got tattoos." Raph's weapons had been returned to his belt and he stepped closer to examine some of the artwork on the guy's arms.

"Raph." It was meant to be an order to step back. Leo didn't care if this guy was another version of himself, he still didn't want the others too close to him until they figured out what he was doing here.

Raph only spared Leo a slightly confused glance before he actually reached up and poked the larger Leonardo in the arm. "Dude, are these turtles?"

Leonardo turned away from the clearly irritated Leo and looked down at Raph next to him. It was a strange sensation to look down at this version of his brother. He couldn't remember the last time he could look down at Raphael. This red-clad turtle may be shorter than his own counterpart, but his neck and arms showed a matched interest in weight lifting. And when Raph's big green eyes looked up to meet his own, he couldn't help but smile down at him.

"Yes," he finally answered, "some of Michelangelo's early work."

"Ya let Mikey tattoo ya?"

Now he was grinning and turning his body towards Raph and his incredulous look.

"Well, let's just say I owed him one and this is how he asked to be repaid. So I went with turtles. I figured it was simple enough that they'd actually look like turtles at the end of it. How'd he do?"

An unexpected growl rose up Leo's throat as he watched Leonardo actually flex his damn bicep in Raph's face. The unusual noise, especially coming from Leo, had Raph turning his attention away from the shifting inked turtles to send Leo another confused look. But before he could voice a question, Mikey came bounding back into the room. And based on the amount of chocolate in the youngest turtle's hands, Raph could already feel the headache he was going to have later when sugar rush Mikey appeared.

Leo turned his attention back to the youngest as well. "Mikey, when we're interrogating an intruder in our home, you do not just -," Leo's indignant lecture was cut off as Mikey tossed him a chocolate.

"Here ya go, big guy," Mikey said, tossing another to Leonardo who caught it easily with a smile in thanks.

"So, listen, do you guys happen to know Usagi?" Blank stares answered Leonardo's question and he shrugged internally, knowing that it was a long shot for him to have still landed in the dimension where his friend lived. Obviously if Usagi had a set of ninja turtles in his own world, he probably would've mentioned them to Leonardo by now. "But you do have a Donatello, right?"

"Leonardo." Their father's stern voice filled the room and let that one word work to demand an explanation.

"Um, sensei," Leo said, glancing quickly between his father and the new guy.

"Sensei," Leonardo quickly repeated with a deep bow towards Master Splinter.

Leonardo smiled fondly when he rose and Master Splinter tilted his head slightly as he quickly recognized this other incarnation of his eldest son.

"You're tall," Leonardo said. "Funny how he'd end up so tall, when you guys are so -," he cut himself off and turned away from the suddenly frowning other turtles and back towards their father. "I'm sorry for the unexpected intrusion, sensei. I seemed to have landed in the wrong dimension."

"You were dimension hopping on purpose?" Leo asked.

Leonardo nodded and pulled what looked like a remote out of his belt. "There seems to have been a malfunction in the technology. That's why I wondered if you had a Donatello. Maybe he can take a look at it?"

"Cool, bro." Now Mikey was getting too close to the other turtle with awe in his voice as he eyed the tech. "Can I -,"

"No," Leo and Raph managed to say in unison as Raph pulled Mikey back a step. Raph also managed to catch the grateful look in Leo's eyes when he did it.

"We do indeed have a Donatello, but he is currently with Miss O'Neil at her farmhouse," Master Splinter supplied. "Leonardo, please call your brother and ask that they return first thing in the morning. I do not wish for them to try to drive back this late at night."

"Hai, sensei." Leo turned away from the group in order to pull out his T-phone.

"And you, Leonardo," Master Splinter said, directing his next statement to the misplaced turtle, "are welcome and expected to stay here with us until you are able to return to your own home."

"Thank you, Master Splinter. It may be a few days. My family thinks I am visiting my friend, so they won't be aware that I'm missing right away."

"You are welcome here as long as it takes."

Leonardo bowed once again to the ninjitsu master and watched as Master Splinter turned and headed back to his own room.

"Donnie will be back tomorrow around lunchtime," Leo said, returning to the group.

"Was he mad?" Raph asked.

"What am I interrupting?" Leonardo asked after he watched the grins exchanged between Raph and Mikey after Raph's question.

"Just Donnie and April's first big weekend getaway," Mikey said with a wide grin. "On Friday night."

"Wait, Donnie and April?" Leonardo was floored.

"Yes, although try not to say it like that when they're here. It's a fairly new relationship," Leo said, immediately defensive of his younger brother.

"Ten years in the making," Raph muttered.

"I know some guys who move even slower," Mikey said, while refusing to make eye contact with anyone in the room as he unwrapped another candy bar.

"Well, that's another clear difference in our worlds," Leonardo said, picturing his own Donatello and April. "I mean, Donatello and April are good friends, but she's dating Casey Jones, a police officer we met while defeating the Kraang."

"Police office?" The sound that came out of Raph was close to a guffaw and had Leonardo's attention zeroed in on him again. "Seriously?"

Leonardo smiled and nodded at Raphael. "Am I okay to presume that you have a Casey Jones?"

"Yeah, and he's a vigilante, hockey playing pain in the ass," Raph said, still laughing.

"Well, ours is a police officer, hockey playing pain in the ass." Leonardo wondered for a moment if he could make his own Raphael laugh that easily. He hadn't really tried in a long time. For now, he was going to enjoy his time with this other Raphael. "Plus, out of the four of us, Michelangelo thinks he has dibs on April."

That got Mikey's swift attention away from his fifth candy bar. "Whoa, really?"

"I think its time for bed," Leo interjected.

"You can sleep in my room, Leonardo," Raph said.

"What? No." Leo had never reacted to anything so quickly in his entire life.

For the third time that night, Raph turned his confused head quickly in Leo's direction. "Fearless, I have that futon in there plus my hammock. It's fine."

"Then I'll sleep on your extra bed," Leo said, doing his best to sound confident and casual. He turned to Leonardo, which also allowed him to block Raph from Leonardo's vision. "You can have my room. I assume you know where it is?"

"Sure," Leonardo said, his own blue eyes amused once again. He bid the smaller turtles a good night and turned towards Leo's bedroom. "I'll try not to finish off the dark chocolate," he called out over his shoulder.

"Let's go, Raph," Leo said. He turned and headed towards Raph's room, relaxing only when he heard Raph follow behind him.

Mikey watched them all head off to bed before half-heartedly saying, "Um, Donnie's bedroom is open."


A/N: So, Ninjazure posted this really adorable picture of 2016 Leonardo on Tumblr recently, and I immediately wondered if they'd be interested in drawing a little pic for this piece. I had requested 2012 Leo glaring at an amused 2016 Leonardo and not only did Ninjazure DELIVER, but "unimpressed Raph" was thrown in there as well! If you'd like to see the ENTIRE picture (it's the cover art for this story but it's been majorly cropped by this sit - you cant even see Raph), I've added it to this story (at the end of chapter 1 and as chapter 6) on the archives/AO3 site and its also been posted on Tumblr (username Reader115 on both sites - Ninjazure has it posted as well).

If you're a RxL fan, you really need to follow Ninjazure on Tumblr. There's some incredible OTP artwork happening over there (including some fun collab stuff with Sakycchan!)
