[Chapter 13- Island]

"Okay, so what's the plan?" GoGo demanded through the headset. Without Baymax's "dreamland" armor, they hadn't been able to fly to the island by themselves. Instead, Fred had gotten the butler, Heathcliff, to prepare the family's helicopter and fly them there.

Wasabi was freaking out about heights the moment the machine started, and the noise from the blades and wind had been impossible to hear over, so they had to talk through old-fashioned, clunky headsets that came with the helicopter. Hiro had been moved to the middle of the seats, since everyone was starting to worry about him. He was playing silently with a stuffed Baymax that Honey Lemon made for him.

Tadashi had been reading the history of the island from one of Fred's mobile computers. It wasn't a laptop, but it wasn't just a touchscreen device either... Tadashi suspected it hadn't been released to the public yet and wondered how Fred got it.

GoGo's question interrupted what had been a relatively peaceful and boring flight. Hiro looked up suddenly, mumbling something that didn't seem to make sense to anyone else and definitely had to do with the "dreamland." Tadashi ran a hand over his face anxiously.

"We're going to the island from Hiro's 'dream.' We know the experiment that lost Callaghan's daughter happened there, but maybe we can find proof that he's doing something now?" The older Hamada repeated for what he felt was the millionth time.

"Yeah, I got that," the dark haired girl snapped. She spun away from the window to glare at him. "I'm asking what's the plan? Are we just going to wander around the island all day, hoping we find some evidence? When we have evidence, what are we going to do with it? Give it to the police? If this dream world is real, they aren't going to be able to do anything!"

"Guys..." Honey Lemon whispered, concerned. Tadashi scrubbed both hands through his hair and waved her off.

"Hiro can bring us directly to where the evidence should be. I just... I just need proof that this is actually happening before we start planning how to take Callaghan down, okay? Right now, I only have my brother's oxygen-deprived hallucinations, some suspicious looks, and a piece of paper!" He buried his face in his hands.

"Dudes! Prepare for landing!" Fred cheered as they finally pulled over the island. Everyone braced themselves, but Heathcliff brought them to a gentle stop in front of a greying, dilapidated building.

"Guys! Our first landing together as a team!" Fred cried and hopped out of the helicopter. He gave Heathcliff a quick fist bump before helping Wasabi out.

"Um, quarantine?" The dark skinned teen questioned, gesturing to the signs around them. "Do you people know what quarantine means?" Hiro blubbered something that sounded like a textbook definition. He waddled forward, a bit like an overgrown toddler.

The boy giggled to himself, and the older teens exchanged concerned looks.

Still, they followed him into the building. Fred began to sing somewhere along the way, and Wasabi barely held back from punching him in the face. Hiro waved his Baymax stuffie around, smiling like he didn't have a care in the world. GoGo and Tadashi trailed behind everyone.

"Are you sure he knows where he's going? Does he know he's leading is?" GoGo demanded.

"He's been here before, or at least he thinks he has. Even if he doesn't know what we're doing, he'll lead us to what he remembers most," Tadashi assured.

They seemed to move deeper and deeper in the building, with everyone becoming more and more anxious as the minutes passed. Hiro began to pay more attention to their surroundings after a little while; he looked like he recognized where they were. He was also starting to look less insane and childish, so Tadashi quickly tried to speak to him.

"Hiro? Hiro, can you hear me?" He asked, keeping his hands steady on the younger brother's shoulders. Hiro stared at him blankly for a moment. His mouth was open slightly, making him look a little stupid. After a second, the boy snapped out of it.

"Tadashi?" His voice cracked.

"Hey, knucklehead," the taller greeted warmly. Relief was the only thing he could feel, knowing Hiro, the real Hiro, was in there somewhere. "Do you know where we are?" The smallest of the group looked around nervously, his small hands clutching the Baymax toy to his chest.

"Callaghan's hideout..." He murmured. "But how are you...?"

"Still alive," Tadashi repeated. "Never died. Hiro, we need to see if Callaghan is really doing anything. Can you bring us to any real evidence? We just need proof that's he's planning to hurt Krei."

"But it's real?" The heartbroken voice whispered.

"Maybe," Tadashi bit his lip, worrying at it. Hiro started to look around and think about their location. His eyes started to glaze over. Before he was completely gone again, Tadashi quickly hugged him and muttered encouragements in his ear.

Then Hiro was gone.

Tadashi held back tears, still hugging his brother. The younger began to squeak and gesture with his toy. Honey Lemon sniffled at the scene, and GoGo turned away. Fred and Wasabi were quiet.

Tadashi released Hiro and held his hand. The smallest Hamada lightly tugged them forward to another hallway. He smiled up at his big brother, and the older sadly smiled back.

Hiro brought them to a dark room with several monitors and advanced computer systems. It was strange to see some screens were still on, and Tadashi finally remembered the power shouldn't have been on either.

"Um, guys...?" He started. Hiro pressed a few buttons on one of the consoles before jumping behind Tadashi and burying his face in his older brother's side. "What's this, Hiro?"

A video began to play, and the teens watched in various states of discomfort. They weren't surprised to see that it was Callaghan's daughter in the flight, or that the portals began to collapse. What they did notice was that the scientists in the video had been working on these computers.

As each noticed it, they turned around to face the broken portals. Portals...?

"Guys," Tadashi repeated, panicking slightly. "They would have left the one broken beyond repair, but they would have dismantled the other one!"

"So who's been building it?" Fred asked.

"Well we know it wasn't Krei," GoGo snapped.

"But how is Callaghan doing it!" Tadashi paced. "He can't have the... the microbots..." He noticed a shiny black object, glinting in the dim lighting.

His heart raced as Hiro began to whimper and cover his ears. Honey Lemon tried to shush the kid, but the boy was staring out into the portal room, freaking out.

"B-Baymax... Baymax!" He cried, and that's when Tadashi knew they had to go. The older Hamada quickly scooped Hiro into his arms and took off down the hallway. The others followed, shouting in confusion.

Just when they reached the entrance to the building, they saw a boat pulling up in the water. Tadashi wanted to make a dash for the helicopter, but he knew they would be seen for sure, and he didn't want Callaghan coming after them.

Instead, he waved Heathcliff away. The butler was confused at first, but Fred waved him off as well, amongst cries of dismay.

Then, the older brother quickly spun around and led them back into the building. He ran the opposite direction of where they'd come, and that's when the others caught on. Hiro squirmed to be let down, and when he was, he darted ahead, leading them somewhere safe.

The area he brought them to was dark and secluded. Tadashi wondered how he knew this was here. Hiro began to trace on the wall, making what looked like a very jagged circle.

"What do we do?" Wasabi hissed. He gestured wildly and began to pace.

"I don't know. But we need to have a plan in case he comes he," GoGo declared.

"He's not going to come here," Tadashi muttered. He carefully looked over Hiro, making sure he hadn't gotten hurt in their escape. "He has no reason to suspect any one is here with him."

"How are we going to get the helicopter back?" Honey Lemon asked quietly. She played with the ends of her hair, looking pale and frightened.

"I can just call Heathcliff once we get outside," Fred reassured. He offered his phone to her, and she shook her head with a slight smile.

"Well. This is bad," GoGo leaned against a wall and slid down to sit on the floor. The other followed her lead. Hiro toddled over to her and managed to get her to play chopsticks and slide. After a while of sitting in silence, everyone joined the game, clapping and singing, laughing and cracking jokes. There was a blanket of caution that rested over them and kept them somewhat quiet, but other than that they let go and enjoyed themselves.

After an hour or so, Fred got a text from Heathcliff, saying the boat had left the island and they could come out now. Fred confirmed they were okay, and everyone ducked outside in time to see the setting sun.

It was a beautiful view from the helicopter as they flew home.

A/N: QUESTION OF THE UPDATE: Would you rather fly across the ocean or sail across the ocean and why? I would always fly because planes don't actually crash all that often, and I get really nervous around too much water.
