Chapter 1

Fred couldn't stop grinning. His dad was a superhero. He was busy saving the world. Best of all, his dad was proud of him. The pair walked side by side through the halls of the mansion. Fred's dad was beaming at his son as Fred recounted Big Hero 6's first adventures. "… And then I realized that they weren't actually my arms! I mean come on, how dumb am I?" Fred said spinning his arms excitedly.

"So how's he doing?" Mr. Lee asked, interrupting his son.

"Hiro? He's doing a lot better, going to SFIT and he just finished rebuilding Baymax," Fred replied, confused.

"That's good, but I meant the tall one. Is he out of the hospital yet?" Mr. Lee smiled. Fred froze. His dad could never seem to keep his friends' names straight. GoGo was the spunky one, Honey was the sweet one, Wasabi was the neat freak, and Tadashi was the tall one.

"What… He's… Dad…" Fred stammered, unsure how to say it.

"I was passing through, to pick up supplies for a job on the East Coast when I saw the fire. I'm sorry I didn't get there earlier. The nurses at San Fran Hospital said he had a decent chance of survival. I haven't had a chance to check up on him yet."

"Tadashi's alive?" Fred breathed. His dad gave him an odd look.

"You didn't-" he started to ask, but Fred cut him off.

"HE'S ALIVE! Come on Dad, we have to go see him!" Fred took off for the front door at a dead sprint, leaving his dad to catch up.

Fred stared through the glass at the figure in the bed. Gauze covered most of the figure's face. Tubes disappeared beneath the blankets and a dozen different monitors blinked. According to the nurses, the John Doe was left at the hospital with no identification. He matched no missing person reports and they'd kept him heavily sedated since his arrival because of the severity of his injuries. His lungs had been damaged by smoke inhalation and he was on oxygen. Most of his body was a mess of second and third degree burns. Chances are he'd never walk again. He had two shattered vertebrae in his lower back and nerve damage from the third degree burns on both legs. The skin grafts were healing well. Fred leaned back from the glass as his breath began to fog up the window. The moment he'd seen the guy in the bed he'd know it was Tadashi. He'd recognize that face anywhere, even half covered in gauze. The nurses had offered to let him go in, but Fred preferred to stay outside. Hospitals made him nervous. His dad had left a half hour before. Fred knew he had a phone call to make, but he didn't know what to say. He could hardly tell anyone that his dad, a superhero, just happened to be passing through and decided to save Tadashi. Fred had been sworn him to secrecy. With a sigh Fred pulled out his cellphone and dialed the Lucky Cat. Hiro answered on the third ring.

"Hey Fred."

"Hiro… You need to come to San Fran Hospital. Bring Baymax and Aunt Cass," Fred ordered. Fred's voice was dead serious and that scared Hiro.

"What's going on? Is everyone alright?!" Hiro asked. There was a frantic edge to his voice.

"The gang's all good. Just hurry," Fred replied before hanging up.

Twenty minutes later Fred met Cass, Hiro, and Baymax in the hospital lobby. Cass was going off on him for making her close the café early. Hiro was nervous. Fred's serious demeanor had him on edge. When Fred stopped joking it was a clear sign that something big was up. Fred ignored their badgering and led them to the third floor intensive care unit. He pointed to Tadashi's room. Hiro shrugged and opened the door. He and Baymax went in. Cass followed her nephew. Fred held the door open and tried to dodge Cass's death glare. This wasn't something he could just say. They had to see it for themselves. Hiro took tentative steps towards the bed. When he was close enough to see the unbandaged part of the patient's face he froze.

"No…" Hiro whispered. It was all he could get out around the lump in his throat.

"What's going on?" Cass asked.

"Tadashi!" Baymax announced happily. Hiro it to the bed before Bayman even finished. He hovered over his brother. Tears were running down his face, as he gently took one of Tadashi's bandaged hands in his own. The world around Hiro faded. All that mattered was his brother's hand in his and the steady beep of the heart monitor.

Aunt Cass was crying and demanding answers from the nurses. Fred stood out of the way. Baymax went to stand beside Hiro.

One of the nurses brought Hiro a chair. He let go of Tadashi just long enough to slide the chair next to the bed.

"I don't know what to say other than thank you," Cass told the doctor. Her eyes were red from tears, but she couldn't keep a smile off her face. Tadashi was alive.

"Just doing my job," the doctor replied. He turned to look at Tadashi. "He's got a long road ahead of him," he muttered absently.

"Yeah," Cass agreed. "We'll figure it out. I can get a reverse mortgage on the Café and I've got some money saved away. Whatever you need to do, do it. I'll find a way to pay for it."

Up until that moment, Fred had been leaning against the wall across the hall, forgotten. "That's not going to be an issue, Ms. Hamada," he said. Cass blinked in surprise. She hadn't realized Fred was still there. He pulled a folded slip of paper out of his pocket and handed it to Cass. "My dad says to move him to Hilltop when he wakes up. They've got the best burn ward in the whole San Fran valley."

Cass unfolded the check and stared. "This is a lot of money Fred," she whispered.

"Tadashi's my friend and I don't think he's going to be getting out to the hospital for a while. Plus there will be follow up stuff. Physical therapy and that kind of stuff," Fred explained. He shuffled his feet and looked at the floor. Cass nearly tackled him in a hug. She didn't say anything, just squeezed him until Fred was sure his ribs were going to break. When she finally let go, Fred was gasping for breath. The tears in Fred's eyes weren't lost on Cass.

"I don't know how to thank you, Fred," She said.

"You don't need to. Just let me know what's going on." The two stared at each other for a moment. "I should probably go tell the others," Fred excused himself. Cass let him go.

The nurses brought in another chair and she took a seat beside Hiro and Baymax.
