Superboy and Core walked down the halfway, the latter humming Mission Impossible (not that the super knew what that was) as they went. He would occasionally peek into a room, 'oo'ing and 'ah'ing at different intervals.

"This place is pretty nice," Core grinned, arms behind his back. "Though, I guess it does get lonely when you're the only one around."

Superboy stopped for a moment, thinking that over, "I guess. It's not that bad."

"Sure. This the room? Looks pre-etty cool."

"Yeah, Canary always has us use this room for training and not the others since this is also a tourist destination."

"So that's what all the people were here for! Makes sense. Alright, step right on up," Core flipped onto the sparring platform, spinning to face the super with his arms out wide. "Ready to sweat, Superboy? This'll be awesome."

"Whatever," There was a small smile on the clone's face as he met the other on the platform and he cracked his knuckles.

"When you do your hopping thing," Core laughed at the super's annoyed expression. "You usually crack the floor, yeah?" When he received a nod in response, he continued, "Well, we're going to fix that."

The two trained for two hours, Core directing Superboy on how to jump and land. He gave him pointers on how to center his weight so he would land lightly. He had the super practice multiple times until he was soaked in sweat. "Come on," The temporary mentor urged, a smile on his face. "One more. I know you got this. Come on, Baby Blue."

Superboy took a deep breath, closing his eyes, before taking a leap. When he landed, it wasn't with the usual crashing sound accompanying it. He looked down and noticed that the ground was perfectly in tact. Nothing out of place. He looked up to see Core's proud expression, the first one he'd ever received from any teacher.

"Oh, you are just amazing!" Core grinned widely, clapping his hands, "Gods, I'm so proud of you! Now, we can get you a form!"

Superboy was going to respond when he tilted his head, "Someone's coming!"

Core made an 'o' with his mouth before he jumped up and over the rafters, crawling into the vents. Just as he left, Robin and Kid Flash came into the training room. "Hey, Supey," Kid smiled. "What'cha doing?"

"Training," Superboy said in his blunt way, like it should've been obvious.

"I can see that," Robin studied the super. "You're drenched in sweat! What did you do?"

"Control," The blue-eyed hero answered, going to a shelf to grab a towel.

"Make any progress?" Kid asked.

"A bit."

"Can we see?" The speedster wondered, looking excited.

"I guess." Superboy prepared for his leap, taking a deep breath. He jumped and the landing was smooth and neat, shocking his two teammates.

"Holy crap, SB!" Robin exclaimed with a wide smile, "That's more than 'a bit'! You have to tell Canary!"

"Not yet. I'm not done with my training," The super said. "I'm going to get something to eat."

"You're really impressive," Core smirked as he popped a blueberry into his mouth. "You've made so much progress in such a short amount of time."

"Oh, yeah?" Superboy looked over at the other, who decided to roll around on his desk chair.

"Mmhm. It's amazing to watch. Get a form and you'll be almost unstoppable."

"Guess I just needed the right teacher."

"Aw, you flatter me. Hey, so, how you liking your team? Do you... Feel the aster when you're with them?"

"It's... I'm not used to them yet so it'll take some time. I like them, though. They're... Nice."

"Good. Here, catch," Core tossed a blueberry to the super, who automatically caught it in his mouth without thinking. "That's awesome."

Superboy blinked in surprise, chewing slowly on the food, "How's the form going to go?"

"Well, it's..." Core rubbed his chin in thought, "Here, let's push the bed against the wall and move the desk away. I think I can have you start practicing in here."

The super stood, easily moving his bed over. He looked over to see Core holding up his desk with one arm like it was a dinner platter or something as he used his other to push the rolling chair, "I have a question."

"And I most likely have an answer," Core smirked, popping another blueberry in his mouth. "What's your question?"

"How come Batman let you stay with him for so long? I mean, you had to be a stranger first. How'd you gain his trust?"

"Hmm," Core placed the desk down, flopping down on the chair. "I guess it was because I saved Little Robbie's life."

"Wait, Robin? What happened?"

"Bats was taking the kid out to the park, the one here with a lake, and some kids pushed him in when Robin didn't know how to swim yet. Of course, no one was going to save the little guy so I did."

"Wow," Superboy looked to his right in thought, picturing his teammate now. "Thank you."

Core tilted his head, "For what?"

"Saving him. I... Like... Having him on the team."

"Oh. Well, then, you're welcome! Now, about that form," The nineteen year-old clapped his hands once, a grin making it's way onto his face. "Ready?"

"Yeah."

"Good! Now, it's kind of like... Dancing, I guess."

"Dancing," Superboy deadpanned, crossing his arms.

"Yes, dancing," Core tossed another blueberry at the super, who caught it in his mouth once again. "Come over here, I'll show you." When the clone walked over, he began talking again, "Okay, so, your side is facing the door." He turned his body, demonstrating for the clone to do the same. "Then, your left foot goes out while your right stays back. With your right arm, punch forward while your left protects your side. Really, it's just; step out and punch. Practice that for a little until you can do it without thinking."

Core gave him ten minutes, going through the motions with him and occasionally fixing his stance to the best placement. "Got it? Okay, the follow up move with that is a left hook. So, you'll step out with your left, punch with your right, and follow up with a left hook. You'll want to do that fast, not slow. This'll help you in your battle with your team so you don't have to focus on doing different moves. Practice this in the training room with your team or even by yourself sometimes."

"Right," Superboy nodded, finding the instructions easy to follow. "What about dodging?"

"I'll have to show you that in the training room," Core said. "But work on this for now and tomorrow, if no one's at the mountain, we'll head over and I'll show you ways to dodge, okay?"

"Alright," The clone nodded and they went through the exercise a few more times.

"Okay, take a shower. You're going to have to rest up a bit. Rumor has it you have a mission in morning."
