A/N Actually, this is my worst chapter. Oh well.
The (Mass) Realisation
What could be worse than phasing through your desk in front of the people you know? Phasing through the roof of the classroom below that desk in front of strangers, of course. Danny surveyed the classroom he phased into. This classroom was full of other freshmen, though he hadn't met them before. "Uh, sorry, just passing through." Apologised Danny through gritted teeth. And through the ceiling. And the floor of his classroom. And through his desk. If this was a 'normal' day at school, a few students would've laughed, maybe chucked some paper at him, but that would be all. Unfortunately for Danny, today was not normal. Today was his first day back as a ghost, so naturally, like most people do when they see a well-known superhero use their powers, cheers erupted and the classroom became a... well, anything but a classroom. Desks were flipped, students ran down the halls, and there were screams of "DANNY PHANTOM!" "There's that kid who saved the world!" "Sign my book!" "Sign my face!" "There is a literal ghost in the classroom." and, "EVERYONE! That Danny Phantom kid's in our class!"
Even the teachers thundered up and down staircases to meet the child with ghost powers, readying pens and paper for autographs and begging to see him in action. A very stressed Danny sunk lower in his chair, and looking to Sam and Tucker for approval, overshadowed the two of them and flew into a nearby cleaning cupboard. "Guys." He whispered in a barely audible tone. "I don't know how I'm going to cope with school now." The cleaning cupboard was ironically dark and dirty, which usually could stop anyone who wasn't a cleaner from going in. Unfortunately, the word 'usually' was in the sentence, and this was anything but the usual for the trio. They heard the stomping of students' and teachers' shoes coming down the storeys, and there wasn't a certain place to escape to without fans destroying it. As the first fleet of students raced down the hall, Danny calmly stepped through the closed door and sighed. He brushed his hands across his jeans and breathed deeply. These were only people who wanted to see him. They weren't threats.
As if the previous destruction and chaos hadn't happened, the excited people formed a line that went three storeys up before stopping, to the absolute confusion of Danny. He quietly cleared his throat. "So... Why is everyone following me?" He asked, defeated. Everyone shouted at once, though there was one key word: 'Autograph!'
Danny hurriedly signed slips of paper, books and assorted items to the surprise of his friends, who had peered out of the cupboard. Between signatures, Danny talked casually to his friends. "You're really going to sign three storeys' worth of autographs?" Asked Sam, incredulous. "I know it's dumb, but I don't get as tired as before, so I'll be fine." Danny reassured his friends. "It's just a few-" He paused. The ghosts had been reluctant to come back in the last few days, as some were recovering and others didn't want to fight someone who had helped them save their world. But that familiar sense of deep, bright, pure cold in Danny's chest rose through his body into his lungs, and his breath grew blue and foggy. "There's a ghost nearby." Danny handed the chewed, pink pen and sticky note back to the screaming fan, before grabbing hold of his friends hands and speeding intangibly out of the clogged school.
