In the next day, Shadow helps Danny and Abby to capture Skulker and Thrasher and Abby acts more grateful than the other times Shadow helped her.
"Thank you, Shadow." Abby says.
"You're welcome," Shadow almost calls her 'sister'. "Abby. Friends now?"
"No. Just allies. At least as long as I'm willing to give you the benefit of the doubt." Abby responds.
"I see the lecture from your grandparents helped you to be more open-minded." Danny comments.
"Talking about them," Abby says and then directs herself to Shadow. "Shadow, my grandparents want to meet you."
"What for?" Shadow asks, worried.
"They just wanna meet a full ghost and since all other good ghosts Dad knows barely leave the Ghost Zone you're the perfect candidate." Abby lies, seeming to be convincing enough.
Danny whispering on Shadow's ear. "Go ahead, son. Maybe you'll even feel confidant enough to tell them the secret."
"Alright, Abby. Let's see the Fenton Seniors." Shadow says.
"I'm going with you." Danny says.
"NO!" Abby screams and then pauses to make up an excuse. "I mean, you need to help Mom with Aunt Jazz's surprise party."
Reasoning that it would help his children's ghost halves to get along he leaves them by themselves and joins Sam with the preparations for the party.
"Danny, do you really think it was a good idea? What if your daughter and your parents are up to something?" Sam asks worried.
"Sam, during all the time my parents hunted me they never were clever enough to pretend to trust me." Danny explains his optimism regarding this. "Even during the temporarily alliance Dad and I formed when Plasmius put a bounty on my head as part of a plan to steal the Fenton Portal he didn't hide the fact he hated the idea of us working together."
"I hope you're right, Danny." Sam says, still preoccupied.
Abby and Shadow arrive at Jack and Maddie's home and head to their lab.
"Hi, Abby. And you must be Shadow." Maddie says.
"Nice to meet you, Ma'am." Shadow responds, being careful not to call her Grandma before trusting her into the secret.
"Grandma, where's Grandpa?" Abby asks.
"Oh, he's in the kitchen helping himself with some fudge. Why don't you call him while I show Shadow around the lab?" Maddie says.
"Sure, Grandma." Abby replies.
After Abby flies away from the lab, Maddie activates a device that cancels out some of Shadow's powers. He tries to fly away but can't phase through the wall. He even considered revealing his identity but unfortunately he can't turn human again. He's captured and locked inside a cage.
"Lemme go! Lemme go! You tricked me." Shadow demands, upset about being tricked.
"Did you really think I had trusted you? Or that my grandparents actually believed a ghost could be good? Specially one so bent on destruction like you?" Abby asks with an evil smile.
"Maybe Danny would fall for your tricks because of how he was unfairly hunted in the past but for the same thing be true with us, you would have to be a half-ghost and since we accept half-ghosts you wouldn't have hidden it from us. And the only one who would know how to become a half-ghost is Jake and you can't be him because Abby saw you both together and you can't be in two places at the same time." Jack explains.
"Duplication powers, duh." Shadow says, annoyed.
"Oh, fine. There's it." Jack admits, a little angry that a ghost pointed it out. "It wouldn't be the first time a half-ghost pulls that stunt to cover up. Plasmius did the same in the past. But I still don't believe you're Jake."
"Your device prevents me from returning to my human self but if you remove my bandana," Shadow himself can't do it since he's tied up in an examination table. "you'll see my face."
"We won't fall for your tricks, ghost." Maddie says with an angry look. "Now you'll tell what evil plan you have on your mind or else we'll torture you for the truth even if we stay here the whole night."
"But what about Aunt Jazz's party?" Abby asks.
"You don't need to worry about that, Miss Abigail." A mysterious voice says.
Abby prepares a fighting stance. "Who are you, stranger?"
"Don't worry, Abby. This is a government agent from the GiW. He planned the whole thing." Jack says happily.
"GiW?" A confused Abby asks. "I thought they were out of comission even before I was born."
"We remained out of comission for a few years, Miss Abigail, but the recent presence of an evil ghost who managed to trick our ghost hero caused the government to secretly reinstate us." The GiW agent explains.
"And I admit you guys had a clever plan. Will you take him away now?" Jack asks, not really wanting to lose a ghost after capturing him. "I didn't have too much time to make experiments on him."
"Actually, the government trusts your capable hands to keep him locked away." The agent explains. "Just don't tell anybody about that. We don't want this to be of the knowledege of anyone who thinks Shadow is a good guy. Now enjoy the party while I stay here and torture, I mean, interrogate the ghost boy (does anyone still need an explanation?) to learn his evil plan."
"You can torture him, too. We don't care." Abby happily says.
Abby and her grandparents leave for Jazz's party.
"I'll fly the way to Aunt Jazz's, Grandpa." Abby says, not wanting to be driven there (or anywhere else) by her grandfather.
"Abby, I'll drive us there faster then you can fly." Jack proudly says.
"No offense, Gramps. But your driving is the main reason I would rather fly my way." Abby says, a little afraid of hurting his feelings.
Back into the lab, the GiW agent is about to make a shocking revelation.
"Please, Mr. Government Guy. Let me go. I'm not the bad guy." Shadow desperately pleads.
"I know you're not the bad guy. I am the bad guy." The GiW agent says with an evil smile. "And you're gonna pay for betraying me."
"What are you talking about?" Shadow asks, confused by hearing such thing from someone he never met before.
Plasmius leaves the GiW agent's body.
"This is what I'm talking about." The fruitloop explains.
"Plasmius!? How did you overshadow a GiW agent?" Shadow asks, angry.
"This is just some random bystander I overshadowed as part of my plan. The funniest part of it was the fact you actually believed your family would accept you as an ally. Nobody will accept you. You have no choice but truly joining me." Plasmius says, willing to break Shadow's non-literal spirit.
"You seriously crazed up fruitloop. My dad accepts me." Shadow responds.
"You fool! He lied. He was just too afraid of your powers to face you in a direct confrontation. Your Father was just tricking you into a false sense of safety." Plasmius lies, wanting to turn Shadow against his family.
"Liar! Stop it! NOOOOWWWWWWW!!!" Shadow screams, causing a totally unexpected reaction.
With that scream, Shadow not only developed his Ghostly Wail but somehow restores whatever ghost powers were previously cancelled. The Ghostly Wail not only releases Shadow from the table and partially reverts him back to Jake Fenton but also knocks Plasmius unconscious. Shadow goes ghost again and drags Plasmius away. Meanwhile, Jazz arrives at her home and gets surprised by Danny, Sam, Abby, Jack, Maddie, Dani, Tucker, Ashley (in Adventures after a Mistake, Tucker married a woman named Ashley), Matt, Valerie and Tori, who yelled "Happy Birthday".
"Thank you, guys. But where's Jake? Do you think Shadow kidnapped him again?" Jazz asks, worried.
"Don't worry, guys. We can torture him to learn where Jake is." Jack says, forgetting he should keep it a secret.
"What are you talking about, Dad? Do you know where can Shadow be found?" A confused Danny asks.
Before Jack can utter some excuse, Jake appears and shows a tied-up Vlad Masters. Jake's eyes are red with anger and Danny, Sam and Matt are worried.
What do you think it's gonna happen? Please R&R.
