"Bye Lu-chan!" The blue haired girl called out to her blonde friend who was dragging an exhausted Natsu home with her.

"Seeya Levy! Natsu finally tired himself out so I can get some sleep tonight!" Lucy stated excitedly. Levy sweatdropped as she watched a minimized Natsu squirm in Lucy's arms.

Lucy has it tough... As if Natsu wasn't destructive enough when he was grown up. She thought sympathetically.

The blonde celestial wizard trotted down the block and up the stairs to her apartment. Natsu hadn't stirred, except when she had to take out her keys to open the door. She needed to put him down so she nudged him awake.

"Wake up Natsu..." She asked softly, rousing him from his sleep and giggling when she saw his pudgy sleep-stricken face. He rubbed his eyes and looked up at the blonde expectantly. Lucy gestured to her keys and the small boy nodded, hopping down from her arms.

She hummed approvingly as her keys clicked in the lock and the door swung open, revealing her warmly heated apartment. As she about to step in she felt Natsu tug on her skirt gently. She looked down at his weary face with soft pink cheeks and she couldn't help the small squeal that echoed in her head.

"Yes Natsu?" She asked blankly, trying hard to resist the urge to suffocate him in a bear hug.

The once teenager looked up at Lucy warily. "I feel... more tired than usual." Lucy nodded thoughtfully. Today was sunday, meaning that at 12:00 p.m tonight it will have been a full week since he's been affected by that stupid potion.

All his childish energy must be wearing off...

"Yeah, that's probably a sign that this potion incident is coming to an end." Lucy explained, however Natsu still looked quite troubled. He truthfully didn't want it to wear off yet. Sure he missed his body, and he missed using his firepower. When he tried to breathe fire in this body, the strength is diminished greatly and the best he could do was light a candle. Despite all that, the time he's spent with Lucy as a child had been the best.

However, the young dragon-slayer had a bad feeling. He felt strangely hot and was way more exhausted than he'd ever been before. He felt like all his energy was being sapped and drained away.

The duo trudged into the apartment, Lucy locking the door behind her and stretching her arms up in the air.

"Ahhh, it's good to be home~" The blonde grinned, making her way over to the bed.

"Luce..." A small voice spoke and the girl turned in it's direction to see Natsu, he looked kind of pale and like he was struggling with something.

"Are you alright?" Lucy asked immediately, rising from the bed and walking over to him. The boy shook his head and slapped his cheeks lightly, looking up with wide eyes he smiled at Lucy.

"No! I'm fine." He reassured her. There was no reason for her to be worried about him. He was probably hot because of the heat radiating from the apartment, as for the tiredness...well... he HAD run rampant around the guild today.

Lucy looked concerned but nodded, walking off towards the bathroom, probably with the intention to take a bath. As she walked she mumbled something about him catching a cold then disappeared behind the bathroom door. Once she was gone, the dragon slayer sighed heavily and fell backwards onto the bed.

Something just didn't feel right...
