Chapter Three

The Fentons Have Landed

Three minutes before the Fentons arrived

In the living room, Ty was lying on the lounge while Abby sat on an armchair, both bored waiting for their aunt, uncle and cousins to arrive.

"What do you think our Aunt Maddie, Uncle Jack, and our cousins Danny and Jazz are like?" Ty asked Abby, mostly out of curiosity, partly out of boredom.

"Well, Mom and Dad said that Aunt Maddie and Uncle Jack are professional ghost-hunters," Abby answered.

Ty snorted. "Pretty lousy job, since ghosts don't exist."

"I couldn't agree more, Ty, until I did some research," Abby answered, pulling out her computer.

At that, Ty sat up with interest. "Really? What kind of research?"

"I'll show you," Abby said, standing up and heading to her brother, sitting down next to him. On her computer, she typed, "Amity Park." Almost immediately, news headlines detailing ghost attacks popped up.

Ty's eyes widened when he saw some of the headlines, but that turned to a look of disbelief when he read some of the headlines. "Ghost Cops Invade? High School Students Claim That Weird Illness Gave Them Ghost Powers? Amity Park Gets Sucked Into Ghost Dimension Thanks To Ghost King? Jewellery Store Robbed Thanks To Ghosts? Crazy Weather Linked to A Maniac Meteorological Ghost? Amity Park Gets Overrun Thanks To Overgrown Plant Ghost!? Those are nothing but articles about cheap hoaxes and tourist traps, meant to draw in people who are gullible enough to believe in things like ghosts."

"Why do you think it's a hoax? Seems to be too elaborate to be one."

"Abby, no known scientist has proven that ghosts exist. Unless there is solid proof that ghosts do exist, then I won't believe these articles. After all, the Internet can lie."

"That's true, but they do seem legit. I'm sure we could always ask Uncle Jack and Aunt Maddie though when they arrive, see if they are right about these ghost attacks that happen to Amity Park."

Ty didn't say anything, but Abby could still feel the disbelief coming from him. And, she couldn't blame him. Ty was a scientist, and believed in cold hard facts; not newspaper articles floating around the Internet claiming that Amity Park, their mom's sister's family's hometown, was the most haunted town in America. Unless he saw proof that he couldn't ignore, he wouldn't believe that maybe ghosts did exist.

Abby, on the other hand, was on the neutral side. True, she didn't believe that ghosts existed, but those articles had made her curious. Not only because of the ghost attacks and invasions that the articles boasted, but also because, if she remembered correctly, that ghosts were mostly a combination of an obsession and ectoplasm. And it sounded like this ectoplasm was a slimy, gooey substance.

That alone had nagged at her curiosity at the possibility that if ghosts existed, then this slimy, possibly gross otherworldly substance existed too.

But, like Ty, unless there was actual proof that couldn't be denied or faked that ghosts did exist, then Abby didn't trust that the news articles and video clips she had found were the real thing. Especially the ones about this ghost that frequently appeared called Danny Phantom. But, that was subject in of itself, though.

Suddenly, the doorbell rang.

Abby closed her laptop and set it down on the coffee table as Ty scrambled to the door, opening it, Abby just behind him.

Their eyes widened at seeing who was on the other side.

There was a large man in a blinding orange jumpsuit that would put Ty's own orange slime suit to shame with black gloves, boots and collar, and having a huge grin on his face as his dark blue eyes twinkled, a woman wearing a blue jumpsuit with black gloves, boots, collar and utility belt with auburn hair in a bob and violet eyes, an eighteen-year-old girl with waist-long carrot-coloured hair held back by a turquoise hairband, who had aqua blue eyes and wearing, thankfully, not a jumpsuit, but a long sleeved V-neck black shirt, turquoise pants and black flats, and a boy about Abby's age with messy, spiky black hair, icy blue eyes, and wearing a white shirt with short sleeves, red collar and a red circle in the middle, blue jeans and red and white sneakers. The boy had a large duffle bag slung over his shoulder and the jump-suited man and woman were holding suitcases, along with the ginger-haired girl.

In other words, their uncle, aunt and cousins were here.

"Uncle Jack, Aunt Maddie. Uh, hi," Abby greeted awkwardly, while Ty was still looking at his mom's sister's family.

Jack smiled and boomed, "Abby! Ty!", before pulling them into a bone-crushing bear hug. "Good to see you two again!"

Abby and Ty, not used to Jack's bear hugs, began gasping for breath as Danny smirked and Jazz rolled her eyes, while Maddie said, "Jack, dear, I think you may be cutting off Ty and Abby's air supply."

Jack, noticing how uncomfortable his niece and nephew were and how they looked they might faint from oxygen deprivation thanks to his hug, said, "Oops," and released them.

Ty and Abby immediately held their sides as they groaned.

"Ow… I think one of my ribs cracked," Ty muttered in pain.

"I think I nearly fainted from having my breath cut off," Abby gasped, panting.

Jack, meanwhile, looked surprised at seeing how tall his niece and nephew were.

"WOW! I can't believe how tall you two are! I remember when you were this tall," Jack reminisced, showing Ty and Abby how tall they were last time he, Maddie, Danny and Jazz were here.

Ty and Abby smiled awkwardly. Even though Jack, Maddie, Danny and Jazz were family, it had been eight years since the Fentons had visited. Things kinda felt… awkward.

Maddie, picking up on the awkwardness, smiled kindly at her niece and nephew.

"I know it's been a long time since we visited, but I'm sure we'll all get along soon. We're family, after all," Maddie said kindly to Ty and Abby.

"Let's just hope that nothing like the Incident happens again," a familiar voice said.

Ty and Abby turned to see their parents standing behind them, meaningful looks on their faces.

Maddie looked at her sister for whom she hadn't seen in eight years and replied, "I don't think anything like the Incident will happen again this time. But, it could have been worse."

"Yeah; we could've accidentally covered the kids in ectoplasmic goop!" Jack exclaimed. Danny and Jazz looked uncomfortable at this, having at some point in their lives being subject to being covered in ecto-goop, most notably Jazz.

Petunia and Harvey gave Jack a look, as did Maddie, before the adults left to talk and catch up in the living room, leaving the cousins still standing awkwardly in the front hallway.

"So… still recovering from our dad's bear hug?" Danny asked.

Instead of answering, Ty and Abby nodded. They had, during their last two years of being Grossologists, taken some pretty hard hits, but they were nothing like their uncle's bear hug.

"Don't worry, you'll get used to it. Me and Danny have, though sometimes they can be pretty rib-crushing," Jazz assured them. She smirked, and added, "And I still see you and Danny still look kinda similar, Ty."

"What?" both Ty and Danny asked at the same time, before looking properly at each other. Their eyes widened when they discovered that, despite different clothing choices and hairstyles, they looked very similar; it was like looking into a mirror. "Oh, yeah."

"And that means I can still call you Ty's long-lost twin, Danny," Abby said, smirking playfully. Because Ty and Danny looked so similar, Abby had decided to call Danny Ty's long-lost twin brother when they were younger. It had been like a joke between the cousins, and when Danny and Ty were younger, they had done some switch-a-roos, pretending to be the other. When they did that, they would ask their parents who was Ty, and who was Danny. That had been the cause of both confusion and laughter as their parents tried to guess who was who.

And now, eight years later, Ty and Danny still looked nearly identical, much to the cousins' amazement.

"Wow, that's actually pretty cool. I mean, what were the odds?" Ty said, amazed that he and Danny still looked nearly identical.

Danny shrugged and replied casually, "Probably like the same odds of ghosts haunting Amity Park and my parents actually not crazy."

That reply caused a mix of varied reactions. Ty folded his arms and frowned in disbelief, Jazz looked a bit nervous, and Abby's reaction was hard to read, but Danny could detect some disbelief in her reaction.

"There's no such thing as ghosts."

It was a simple statement, but for some reason, it rubbed Danny up the wrong way.

Looking at Ty, Danny argued, "Really? Then how do you explain all of Amity Park's frequent ghost attacks? You can ask my parents; they've hunted and even caught a couple."

"No offence, Danny, but they're probably just a tourist trap, hoaxes meant to draw sightseers in. There's no scientific evidence proving that ghosts actually exist, after all. As for your parents… maybe they didn't actually catch any ghosts, but think that they did."

Danny couldn't help but a feel a tiny bit irritated. He knew that there were people out there who believed that Amity Park's regular ghost attacks were faked, but he knew for a fact they weren't; after all, he fought most of the ghosts that attacked himself. Heck, he was half-ghost. And he also knew that his parents had actually hunted down and captured some ghosts, even though for a limited time on the capturing part, with Danny Phantom being their main target. But still, it annoyed him that his cousins and possibly his aunt and uncle thought that the ghosts constantly terrorising Amity Park were fakes, and that his parents were crazy, being ghost hunters. He was sorely tempted to change his eye colour to a ghostly green and say, "There's also no scientific evidence for half-ghosts existing, but I'm half-living proof that they do." He hated to admit it, but Ty's firm belief in ghosts not existing actually reminded him of Jazz's disbelief and her insistence that their parents were crazy, because of their job, until she saw him transform into his ghost form. And it really annoyed him, and made him want to defend his parents.

Jazz, sensing her little brother's irritation and the growing tension, asked abruptly, "Uh, Abby, which rooms are me and Danny sleeping in?"

Abby, who seemed relieved in the change in subject, answered, "Jazz, you're going to be staying in my room with me, and Danny's going to be staying in Ty's room."

"Thanks, Abby," Jazz thanked, and with a meaningful look to her brother, she headed to Abby's room, which she'll be sharing with her blue-eyed cousin, Danny following.

When their cousins were out of earshot, Jazz hissed to Danny, "What happened back there? You looked like you were going to give Ty the 'Scary Eyes' at any second."

"I don't know. Ty believing that ghosts not existing really irritated me for some reason. It… actually reminded me of when you didn't believe that ghosts didn't exist and when you thought that our parents were crazy since they were ghost hunters before you saw me go ghost," Danny whispered.

Jazz nodded. "That makes sense. But it may be wise if you avoid the subject of ghosts while you and Ty talk in the near future while we're here."

"Duly noted."

Soon, the two were standing in front of Ty and Abby's respective rooms, which they would be sharing with their respective cousins. Jazz opened the door to Abby's bedroom so that she could set down her suitcase and unpack. When it opened, Jazz looked around the room.. and her eyes landed on a poster of a certain singer.

Stifling her smirk, Jazz turned to Danny and said, "Danny, you're not going to believe which singer Abby's a fan of."

Danny frowned, confused, before his eyes widened in realisation.

"Wait, are you saying…"

Jazz, instead of answering, moved aside, letting Danny see the poster that she had seen. Danny's eyes widened before he frowned slightly.

"Great. One of my cousins is a fan of one of my enemies."

Jazz sniggered as Danny scowled at the poster of Ember McLain, which was on the wall just above Abby's dresser. The flame-haired rockstar was singing into the microphone, a crowd cheering her name in front of her.

Oh, the look on Ember's face if she was here right now and saw that Danny Phantom's cousin was a fan of hers…

Giving the poster one last scowl, Danny headed towards Ty's bedroom, which he will be sharing with him. Opening it, he walked inside.

Inside, Ty's room looked pretty normal. There was a closet, a desk and a bed. There were some posters of cars, a poster of the solar system, and a chemistry set on Ty's desk. On the floor, in the middle of the room, was a blow up air mattress, with a sheet, blanket and a couple of pillows on it.

Danny headed towards the air mattress and sat down on it, putting the duffle bag beside the bed. Inside was some clothes that he had packed, and ghost-hunting weapons that he had managed to stow away, just in case; his trusty Fenton Thermos, a wrist ray, a blaster and a Jack-O'-Nine-Tails. Danny knew that it was highly unlikely for his enemies to know he was here, but he had come prepared just in case they did.

Speaking of his enemies…

Danny pulled out his phone from his pocket and checked the Amity Park news.

Thankfully, there was nothing on invasions or uber-powerful ghosts trying to take over Amity Park. There was some reports on a couple of ghost fights, but nothing too major. Sam, Tucker and Valerie really were handling the ghosts alright.

Still, he couldn't help but feel nervous, especially when he remembered how during yesterday and the last week of school before summer, his ghost sense hadn't gone off once. Plus, now that he thought about, he hadn't seen Vlad at all since he had last encountered him when he had tried to melt Dani into ectoplasm. That made Danny grit his teeth and his eyes burn a furious green at what Vlad had nearly done to Dani. Even though he was slightly relieved that he hadn't seen, much less fought, Vlad since then, it made Danny edgy. Because when Vlad was quiet for too long, that meant he was concocting a plan to defeat Danny, gain power, and kill his dad and marry his mom, and-

Fenton, relax. You're being paranoid, Danny thought, but he still felt on-guard.

Wanting to relax, Danny checked to see if Ty or Abby, or his aunt and uncle or his parents were coming to the bedroom. When they weren't, Danny used some of his telekinesis to close the door. When it had shut, he muttered, "I'm going ghost."

The familiar blue-white rings of light washed over Danny, transforming him from Danny Fenton to his ghostly alter ego Danny Phantom. Turning invisible and intangible, Danny phased through the ceiling of the bedroom. Turning tangible but still remaining invisible so as not to cause a panic, Danny flew through the air, the relaxing flight through the night air with the stars around him and the wind in his hair and running over his face calming him down, a relaxed smile on his face.

He flew around for several more seconds, enjoying the refreshing, cool night air, before returning back to the Archer residence. Turning intangible again, he phased back into the room, turning tangible and visible. Checking to see if Ty hadn't come into the room while he had been out flying, Danny was relieved to see that he hadn't, and changed back to human form. As soon as he did, Danny was unaware that the bedroom door was opening…

…

Meanwhile

After Jazz and Danny had walked away, Abby fixed her younger brother with a look.

Ty, noticing it, asked, "What?"

"Ty, that was a bit harsh."

Ty looked at her, and Abby continued.

"Look, I know that you don't believe that ghosts exist, that Amity Park being haunted is a lie. But Danny looked really annoyed back there, and I think that, despite you not meaning to, you offended not only him, but also Aunt Maddie and Uncle Jack. I know that you didn't mean to, but it sounded like you did when you argued against Danny's point."

Abby knew her brother didn't mean to offend Danny; she guessed that the articles about Amity Park being haunted reminded Ty of when, a few months ago, the sewers had been supposedly the lair of a giant alligator, when in reality it was a giant alligator robot made by Lance Boil. Still, Ty had firmly argued that the urban myth of alligators being flushed down the toilet and surviving in the sewers didn't fit with scientific fact all the while during the case, especially when the Detective had believed it to be true because of his own guilt toward him flushing his own pet alligator down the toilet, and that salesman, Professor T.P Skinner, just fuelling the urban myth with his Gator Trap 5000.

Maybe Danny reminds Ty of the Detective; believing in something that isn't actually true?

Ty, who had been thinking over what he said and feeling really guilty that what he said had possibly offended Danny, said to Abby, "I guess I should probably apologise to Danny since I kinda offended him, right?"

"I think so, but maybe tomorrow; it's pretty late," Abby replied back.

With that said, the two siblings walked back to their rooms, which they were sharing with their cousins. Abby opened her door and entered inside, where she saw Jazz unpacking. She also caught her glaring discreet daggers at the Ember McLain poster that Abby had(what? She was a good musician!), but Abby had no clue why. She was about to speak to Jazz when Ty ran into her room, panicked.

"Danny's gone!" Ty exclaimed before Abby could even ask what was wrong.

Abby frowned, while Jazz froze.

"Are you sure that he's actually gone, Ty?" Abby asked her dark-haired brother.

Ty scowled. "I couldn't see him anywhere, so yes he's gone!"

"Maybe he's not actually gone and in another part of the house?" Jazz suggested.

"That makes sense," Abby said, and Ty quickly countered, "Then why didn't either me or Abby see Danny leave my room?"

"Maybe he was invisible?" Jazz joked, but the light tone sounded nervous and forced.

Abby and Ty exchanged strange looks before Jazz sighed.

"Look, maybe he went back into the room while we were talking? We could check right now," Jazz suggested.

Seeing no reason why to not go with that plan, Ty, Abby and Jazz walked out of Abby's room and headed to Ty's room, which was separated from Abby's room by a bathroom. As Ty stood in front of his bedroom door, about to open it, Abby swore she heard Jazz mutter very, very faintly under her breath, "Danny, if you're still out there relaxing, or if you are inside and just invisible to cause me, Ty and Abby to panic, I'm gonna to fully kill you."

That caused Abby to raise an eyebrow, but she decided to question her cousin's strange wording for another day; or, at least, until Ty opened the door and she and Jazz could see if Danny was indeed gone or not.

Slowly, Ty opened the door, and when it finished opening, it revealed his room, the air mattress lying in the middle and the duffle bag next to it… and Danny, standing right in the middle, a relaxed smile on his face and his hair looking like it had been blown by the wind.

At hearing the door opening, Danny jumped, before he relaxed at seeing it was only his cousins and sister.

"Oh, hey guys," Danny greeted, though despite his relaxed air he had a slightly wary and nervous look to his face.

Abby turned to Ty and asked, "Danny's gone, hmm?"

At hearing that, Danny frowned in confusion. "Wait, what?"

"B-but he was!" Ty protested, eyes also wide in confusion. "I saw this bright flash of light from the crack underneath the door, and when I looked inside, he was gone!"

At hearing that, Danny frowned even more and folded his arms, though he still had an air of nervousness to him, while Jazz was glaring at her brother meaningfully.

"Ty, your eyes were probably playing tricks on you. I was here the whole time. What am I, a ghost?" Danny reasoned, the last sentence both a rhetorical question and a jab.

Ty, at a loss for words, gave his cousin a look.

"Maybe you're right, Danny. Maybe you were here the whole time. But I swear, you weren't here. And I swear I saw a flash of light. I know what I saw," Ty muttered, still looking at Danny.

Danny gave an equal look back. "Do you really?"

With that, both cousins continued to look at each other as Abby and Jazz stood there awkwardly, until Abby decided to ask Jazz one of her questions about her strange word choice.

"So, Jazz… what did you mean by Danny being invisible just to make me, Ty and you panic?"

At that, Jazz suddenly looked nervous, but answered, "I meant that Danny, uh, is sometimes so quiet that he may as well be, um, invisible. But, he didn't actually turn invisible. I mean, nobody can turn invisible unless there's special tech involved for that, right?"

Abby wasn't entirely convinced, as she felt like Jazz was lying, but didn't question it. Jazz, who was giving her a weak smile, looked relieved that Abby wasn't asking her any more questions.

Eventually, Jazz and Abby got tired off the stare-off between Ty and Danny and Jazz said, "I think we, um, should be getting to bed now. It's getting pretty late."

Ty and Danny, who's eyes had been seconds away from briefly flashing green for a more intimidating effect, broke eye contact, finding logic in what Jazz had said. Abby nodded in agreement, and with that, the two girls walked back to Abby's room, leaving Danny and Ty to look at each other once before turning their backs to the other, Danny walking out so that he could get changed into his pyjamas and brush his teeth in the bathroom. Once he had finished, he walked back, passing Jazz on the way.

The ginger-haired girl fixed Danny with a look, that clearly meant, Talk tomorrow, that Danny received, before she entered the bathroom. Danny then walked back into the bedroom, noticing that Ty was already in bed. Thankful that he didn't need to deal with his cousin who had come too close of suspecting Danny's secret, the halfa laid down on the air mattress bed and stared at the blank ceiling, before, eventually, he drifted off into a dreamless sleep.

So… this chapter was a pain.

*bangs head on desk*Curse you, writer's block! Curse you, OOCness! Curse you, procrastination!

Yeah, you can blame me if Ty acted OOC. Abby too. And Danny. And Jazz. It was just… argh! It was so, so hard to write Ty and Abby's views about the ghosts attacking Amity Park, and how Danny and Jazz would react to that!

Speaking of Ty and Abby's views to ghosts… I can imagine Ty have a strong disbelief that ghosts exist. Despite the news articles claiming that Amity Park is indeed haunted, he still doesn't believe that ghosts exist, kinda like with how he didn't believe that alligators were in the sewers in the episode "Flushed Away", mostly because science proves that they couldn't survive down there, just like science proves that ghosts don't exist, and therefore his aunt and uncle being ghost hunters when there's nothing to hunt doesn't make sense to him. So, he's kinda like Jazz in that aspect, until she found out her brother's secret identity. Abby, she's more on the neutral side. True, she doesn't believe that ghosts exist as well, but she also can't ignore the strong evidence supporting that Amity Park is indeed haunted. Plus, when she asks Jack and Maddie if they are indeed ghosts, their answer will mostly likely be yes, and they will use Danny Phantom as an example. So, she is also like Danny, before the portal accident that made him half-ghost. And another reason is that if ghosts do exist, then ectoplasm does too. Another gooey, slimy thing that will be exciting to both Abby, and Ty and Lab Rat.

Speaking of Danny and Ty… has anyone ever noticed that they look kinda similar? I know I mentioned it above, where it's described they look near-identical, but they do! They both have spiky black hair, both have blue eyes(if one is to look closely at Ty, they would see that Ty has blue irises), they both have a similar face shape, and both are shorter than their sisters, despite Danny being the same age as Abby. I'm thinking, since Grossology aired in 2006, during when Danny Phantom was still airing, that the writers of Grossology took inspiration from Danny Phantom for character concepts. I mean, think about it. Not only do Danny and Ty look similar, save for clothing styles, but Professor T.P Skinner has the same hairstyle that Technus had in Season One, Sarah Senia is kinda like the female version of Undergrowth, Far-Ty(Ty's evil persona thanks to Fartor)reminds me of Dan Phantom, Danny's evil alternate future self, Chester/Kid Rot(one of my favourite Grossology villains, along with Insectiva and Lance Boil)reminds me of Johnny 13, especially since they both have powers that cause harm to others(Kid Rot's rotting touch, Johnny 13's bad luck Shadow)and they showed an attraction to the main character's sister(although, Johnny 13 was using Jazz, but it still counts!) and both Lance Boil and Fartor remind me of Vlad Masters/Plasmius! Coincidence, I think not!

Also, yes, I made Abby an Ember McLain fan. Of course, she doesn't know that Ember's a ghost, and she became a fan of Ember because she actually liked her music, not because she was mind-controlled into liking it. Of course, this is gonna drive Danny crazy, knowing that his cousin is a fan of one of his enemies, while she's confused about Danny having a huge dislike towards Ember.

Also, speaking of dislike… it looks like Ty and Danny don't get along, but that's mostly because Danny was anxious to get rid of any suspicion towards his secret, and Ty felt embarrassed and a bit anxious that Danny was saying that Ty's eyes were probably playing tricks on him and that he'd been there the whole time when he had claimed that Danny had disappeared. Not to mention, when Ty accidentally offended Danny when he said that Amity Park's ghost attacks are hoaxes and that, in a subtle way, that his parents are crazy for hunting ghosts, despite meaning no offence. They'll try to bond, and they will, but their relationship is gonna be rocky at the start, especially with them both trying to keep secrets from the other(Ty being a Grossologist, Danny being half-ghost). Although, I can't wait for the eventual chapter where Ty and Abby will learn Danny's secret and Danny will be all like, "So, believe in ghosts now, Ty?" Although that chapter is far, far into the story…

Yes, I know that Ty, Abby, Danny and Jazz were acting OOC in this chapter. I tried my best to keep them in-character, and will do so in the chapter after next. Because, in the next chapter, we'll see who the major villains for this story…*grins evilly*. Any bets though, on who they will be?

If anyone can get what the chapter title was referencing to, they will receive a virtual cookie.

Hope you enjoyed, despite Ty, Abby, Danny and Jazz being a bit OOC in the middle and last parts.
