"Finally! School's out, and that means no more no responsibility or work for two months!" Danny exclaimed, as he and his two friends, Sam and Tucker, walked out of the school. It had been a difficult year, with balancing ghost fighting and school work, but it was over, and all students at Casper High were relieved.

"And no more of your lame excuses for leaving class," Sam added. "I'm pretty sure most of the grade thinks you have intestinal problems." Tucker laughed as Danny blushed from embarrassment.

"They don't! I occaisonally provide a different excuse," he huffed. Sam rolled her eyes.

"Sure you do."

"Hey Danny, as sorry as I am to break up this conversation, where did you say we were going again? For the trip you've given us so many details about?" The three teens had decided to visit a remote city in Michigan. Originally, the three had wanted to go to separate places, but Jazz had convinced Danny to visit the city.

"Right, that..." Danny thought for a moment, trying to recall what he had read online, and heard from his sister. "Well, it's the home of Professor Membrane, and I know my parents would love to talk to a scientist. Even if he probably isn't a paranormal one. If they're out of the way, I can go ghost whenever I want, and we can hang out unrestricted. I'm sure there will be cool stuff to check out."

"Go ghost whenever you want? Won't people be suspiscious if Danny Phantom, the ghost is supposedly haunting Amity Park, suddenly appears in another town?" Sam asked, confusedly.

"I'll be fine," Danny replied. "What could possibly go wrong?" Sam and Tucker shared a look, as if they knew exactly what could go wrong. "Anyway, my parents are driving us, so meet at my house tomorrow. I'll text you the time." Tucker gulped nervously.

"Is your... dad driving us there?" He questioned. Sam looked at Danny curious for the answer.

"Don't worry. I'll make sure he stays far away from the wheel." Tucker and Sam both looked relieved.

The trio continued walking in silence, eventually splitting as their houses where in different locations. After a short walk alone, Danny approached his house and let himself in. No one was there. He sighed. His parents were most likely in the lab, still making objects of ghostly doom, even before a trip like this. Jazz had most likely packed their luggage, even though she was too busy with school work to come, even though she had provided the location. Danny walked up the stairs and peeked in to his parent's room to confirm. Their belongings were packed neatly in a way only Jazz could accomplish. He smiled softly, and walked to his room. He hadn't packed his own luggage yet, depite being reminded by a certain older sibling. Danny almost wished that Jazz had packed his, but he didn't want to give the redhead an excuse to snoop around in his room.

Danny started to fold clothes and pack items into a beat up neon-orange suitcase. He had previously wanted to visit Florida, but with Tucker and Sam also wanting to go to separate locations, going to this one place really was best. A sharp pain pierced his head suddenly, making him drop a messily folded shirt. Danny held his hands to his head, shrieking with pain. After a few moments, the feeling mysteriously vanished, leaving him still clutching his head. He sat there for a moment. Footsteps could be heard approching from down the hall.

"Danny! What was that?" Jazz asked him, bursting into her younger sibling's room with concern. Upon seeing him on the ground in pain, she walked over and gave him a hug.

"I'm too old for that, Jazz," Danny said quietly, not wanting to aggravate his head. Jazz backed up slightly.

"Sorry." Danny looked at his sibling, lowering his hands from his head, and saw a surpring amount of concern on her face.

"It's fine, Jazz. I just had a bit of pain for a second. Nothing serious. This seemed to worsen the look on her face, however.

"Head pain?" She asked. Danny nodded. Jazz appeared to process this information, before coming to a conclusion. "I'm coming with you then." Before Danny could protest, she added, "I'm your big sister Danny. I'm allowed to be concerned about your health. Don't worry about Tucker and Sam. It'll be like I'm not even there." He still wanted to protest, but the look on his sister's face warned him otherwise. "Listen. Tell me right away if that ever happens again. Please." And before anything else could be said, she stood up and exiting the room.

'What was that all about?' Danny wondered silently. The look on his sister's face... she looked like she was on the verge of tears. 'But why?'

Standing outside her brother's door, Jazz paused and tried to slow down her breathing. 'This is too soon for this to be happening!' Jazz thought, a frantic tone evident in her mind. After a few shaky breaths, she counted to ten, and started walking down the stairs for a glass of water. Her parents were still in the basement, oblivious to what had occured upstairs. Jazz took a cup, filled it with warm water, and began to slowly drink it. 'It'll be fine,' she assured herself mentally.

'I promised this would be the last time.'

A/N

This is my first multi-chapter fic, it is a crossover between Invader Zim and Danny Phantom. I welcome any and all constructive criticism and suggestions, so please don't be afraid to review! Hopefully future chapters will be longer, but I can't guarantee that, (or a constant upload schedule).
