Once the boys and Alya gathered up their things upstairs unaware that waiting outside for them was Hawkmoth and his men ready to attack.
"Adrien are you sure you won't come?" Marinette asked.
"No."
"Then I guess this is goodbye."
"Yes it is and just so you know you can't ever come back! Ever!"
"Adrien-"
But he just flew off to his room. She sighed, sadly. "Adrien staying here means being young forever but what's the point if you're alone?"
He didn't respond, Marinette left some medicine for him and sadly went upstairs. But once she was out of the house she found it surrounded by pirates along with Alya and the boys tied up and gagged.
"Surprise!" Animan said.
"Adri-Mmmmph!" She tried to scream by Simon gagged her with a cloth before she could.
"Take them away!" Hawkmoth ordered.
Simon threw Marinette over his shoulder and carried her away while the other children were forcibly dragged to the ship by the ropes that bounded them. Hawkmoth then slipped into the fort however it was so small and slender that he could hardly get through and was unable to reach Adrien who was fast asleep. He then saw his medicine on the table, he pulled a vile from his jacket and poured five drops of deadly poison into his medicine.
Back at the ship Chloe managed to bust her way out of the cage she was in and escaped just in time to see Hawkmoth leaving and the poison in his hand. She flew as fast as her wings could carry her hoping she wasn't too late.
Adrien woke up a few minutes later. The entire house was empty, he was alone. It made him feel hurt. He then saw the cup of medicine Marinette had left, feeling guilty for not saying goodbye he decided to take it for her. He had just picked it up when Chloe flew in.
"Adrien! Don't!" She cried.
"Chloe go away!" He said.
"Please! It's not safe!"
But he ignored her and brought the medicine to his lips, in act of desperation, Chloe flew between Adrien's mouth and the cup forcing her to drink every last drop of the poisoned medicine.
"Chloe!" He shouted angrily. "How dare you drink my medicine!"
But his anger changed to worry when Chloe fell to the floor coughing and choking.
"Chloe? What's wrong?"
"It...It was poisoned Adrien." She choked. "Hawkmoth did it and he's taken the others!"
"How? How did he get here?"
"It's my fault! I helped him find out where you lived! I didn't mean for this to happen! I'm sorry! I...just...didn't...want." Her light started to dim. "To..." It grew dimmer and dimmer. "Lose you." Then her light went out.
Adrien picked her up in horror, the sky began to darken and winds blew hard as a storm was started. On the pirate ship, all the children were tied together in a big huddle on the deck.
"You know." Hawkmoth said lifting Marinette's chin up with his hook. "There's room for one more pirate."
"I'll die first." Marinette retorted.
"So be it then. Pidgeon!"
"Aye sir." Mr. Pidgeon tied Marinette to the mast and made the ropes extra tight. "My apologies Miss."
The other pirates and the children looked up to see the change in weather and atmosphere leading the pirates to believe that Adrien was finally dead much to Marinette's heartbreak.
"At last!" Hawkmoth cried triumphetly. "Adrien Agreste is no more!"
"No." Marinette whispered as tears began to fall from her eyes.
The other pirates cheered but the children mourned greatly.
"Chloe! I'm so sorry!" Adrien sobbed. "I don't hate you! You're like a sister to me, don't go!" The sad boy could only think of one thing that just might revive her.
"I do believe in fairies, I do, I do." He whispered into the wind and it carried his cry through Neverland and out into the world. Urging others to do the same thing.
"I do believe in fairies." Marinette said. "I do, I do."
"I do believe in fairies." Nino said.
"I do, I do." Erik said.
"I do believe in fairies! I do! I do!" Chanted Alya and the lost boys.
Soon all the children of the world and some adults including Mr. and Mrs. Dupain-Cheng were shouting the same thing.
"I do believe in fairies! I do! I do!"
And their strong faith combined was enough to revive Chloe who was brought back as a kinder, gentler, and more understanding fairy.
"Oh Chloe!"
"I'm sorry Adrien. Can you ever forgive me?" She asked.
"Yes. Now what happened?"
"The pirates! They took Marinette, Alya, and the boys. I think he plans to kill them or worse."
"Akumatize them, that's what could be worse." He said. "This time he's gone too far!" He grabbed his sword. "It's Hawkmoth or me this time."
The darkened skies faded and the clouds were cleared as sun began to shine.
"He's alive!" Hawkmoth shouted angrily. He marched furiously over to Marinette, cut her loose and seized her by her neck. "How?"
"I...I don't know." She squeaked.
"You know something! Tell me!"
"I um...Well I know that he was very lonely and he wanted friends."
"He needed a lady?"
"I need a lady." Guitar Villain said.
Hawkmoth shot him causing everyone to scream in horror. "Why did he bring you here girl?!"
"I told stories."
"Stories?"
"Yes ones where good defeats evil."
"He taught you how to fly! How?"
"Just think happy thoughts and have positive emotions."
"I have none!"
"Then that brings you down!"
He held his hook to her throat and turned to the other children. "What about you all? One of you must know."
"No!" Kim said.
"We don't know anything!" Alya said.
"Leave her alone!" Ivan demanded.
"Tell me!" He yelled. "Or I will gutt this pretty girl until she's nothing but bones!"
"Fairy dust!" Erik cried. "You need fairy dust."
"Erik!" The other children scolded.
Hawkmoth turned back to Marinette. "Will negative emotions bring him down?"
"He has none. You said so yourself he has no feelings."
"Ugh! How is it that he cannot feel!" He shouted in frustration. "I mean it's-" Just like that realization hit him like a cannon shot out of long Tom. "Of course, how did I not see it sooner?"
"See what?" Marinette asked.
"The way he smiles all of a sudden, the protectiveness he shows. He does feel." Giving her a wicked grin. "He feels for you."
