After explaining things to Tsunade and the others on how she had finally brought Sauske home, Tsunade had them go out and do a few training exercises to make sure that they could still work together as a team, then sent them off on their way once it was established that Naru; for all her power had no real need or interest in using it for much of anything at all from the looks of things.
She and Sakura had run from Kakashi almost all night before the exercise ended. Which meant to Kakashi, Jiriaya and Tsunade that the whole Sauske thing was more or less a fluke.
Not an outright abuse of her power.
Just something small that she had thought would make things simpler on everyone. And to a degree she was right however due to the peculiar nature of the ability she had used to bring Sauske home, Tsunade had tried to ring a promise from Naru that she wouldn't use that ability again.
But Naru had refused merely stating that it was an ability that would be very useful in the future.
She didn't say anything more though she did raise one hand and hold up five fingers and said, "Just five more times then I'll promise you anything you need me too. And I'll stick to my word, but I need this ability just five more times." No one else had said anything more about it figuring that if she was using the knowledge that Kyubbi had given to her, then she must have her reasons.
After that Tsunade mentioned having Naru stop by the hospital for a physical so that she could document any abnormalities in her body, at which point Naru visibly cringed and looked away from the Kage's unwavering stare, nervously and muttered something under her breath about needing to get some lighter fluid and matches to get rid of something.
Sakura and the Copy nin wanted to question Naru about her mutterings but the damn girl more or less ran off the second Tsunade dismissed them.

Kakashi staggered into his apartment a short time later and striped off his flank vest, his shoes, gloves, headband and mask as he flicked on the lights and was about to head back to the bathroom when he turned and nearly jumped out of his skin when he noticed Naru sitting on the arm of his couch with her legs crossed and a slightly bemused look on her pretty face.
Kakashi put a hand against his chest to try and calm the frantic beating of his heart as he glared at her in mock irritation and said in a breathless voice, "Naru baby, you're going to have to start making noise when you appear somewhere or one day you're have an accident." He closed the door and frowned before asking. "What are you doing here? Didn't you run away earlier?"
"I have nowhere else to go. Besides, I like it here. I have good company when I'm here..." Kakashi gave her an uh-huh look and she sighed. "You have questions about what is going on with your memory. I thought I would try to answer them. But you shouldn't get your hopes up. I'm honestly not sure how much help I'll be."
Kakashi cocked his head and gave her a calculating look then asked. "So you really are aware of what's going on with my memory? Even though I never mentioned it? To anyone?"
"It's because my memories are directly linked to some of your own. Your memories of me as a child and my memories of you as a man that I look up too. Our thoughts of one another, the depth of our feelings for one another- These things link us in more than one way. Because of this...you are experiencing some anomalies."
"Are they harmful? I've felt dizzy twice already-" He stopped talking as his mismatched eyes widened a second before he shouted. "Twice! Naru did you do something before? Is that why I got dizzy the other day? Tell me! What did you do?"
Naru flinched a little bit and partially lifted her hands to put them over her ears but was stopped when he grabbed her wrists and pulled her arms down as he invaded her personal space. Her face turned a lovely shade of pink as she looked up at him, his face was just inches from her own and just for a second Naru could see this strange heated look on his face as he stared down at her, waiting for an answer.
She swallowed past the lump in her throat and shook her head and lowered her head as she said in her softest tone. "I didn't do anything. That time was an accident."
"But something did happen." Kakashi said in a chidding tone. Naru didn't say anything. She figured that he'd recall his memory of her trying to pick up her infant self and yelling at her not too, soon enough.
"What happened between us earlier? Before I stomped your foot?" Naru asked suddenly, trying to steer their conversation in a more interesting direction. Kakashi glared at her for a second then sighed. Damn the little foxy chit for asking about that so suddenly.
Now his entrie thought process was consumed with nothing but the need to test the waters and see in what way Naru saw him. "What do you think happened Naru?"
"I'm not sure. For a moment, I felt like I feel every three months-" Kakashi cocked his head and considered her words as she continued speaking. "I felt a very intense need."
"What sort of need?"
"I'm not sure. I've only felt that way once or twice after I woke up but I don't recall much of either experience because Jiriaya kept me unconscious until the feeling went away." Kakashi frowned at her words and made a mental note to speak with Jiriaya about Naru's 'need' at the earliest convenience as he let go of her wrists and stepped back away from her and headed towards the kitchen to fix some small something for dinner before he bothered to ask.
"Are you planning to stay?"
Naru turned on her heel so quickly that she nearly fell over the coffee table as she yelped, "Yes!"
