Hiro and Autumn ran out the door after telling Cass they were going to register.
As they left, they heard some SFIT students on their way to school saying "There's his sista," while pointing at Hiro and then at Autumn. A few others were saying things like, "Yonder's some Hamadas," and "Orange hair, green eyes, wearing dresses all the time. Yup, that's her."
Somehow, they had found out Wasabi and Autumn were in a romantic relationship. Even though no 'drastic' things had been done yet, everyone had been saying things about Autumn.
"Autumn, why are they saying things about us?" Hiro asked; him and Autumn running after Baymax.
"You remember Wasabi?" Autumn asked.
"Yeah, what about him?" Hiro replied.
"He and I are… in love." Autumn replied.
Autumn half-expected Hiro to whack her on the head, but instead, he gave her a pat on the back. "Autumn Lee Hamada… I'm so happy for you! How far apart are you in age?"
"He's 18, I'm 14." Autumn replied.
Yet again, Autumn thought Hiro was going to slap her, but he didn't. He said, "Does Aunt Cass know? Did she tell you two to wait until you two were older to do anything 'drastic', if you know what I mean?"
"Yes and yes." Autumn replied. "Look, there's Baymax!"
They ran after him until they found him at an abandoned warehouse. "Baymax!" Hiro yelled. "Are you crazy? What are you doing?"
"I have found where your tiny robot wants to go." Baymax replied.
"I told you! It's broken! It's not trying to go-" He noticed that the robot was NOT broken after all. The door was locked, but Baymax pointed out a window. That gave Hiro and Autumn an idea.
"Please exercise caution." Baymax warned Hiro and Autumn as they climbed up him to the window. "A fall from this height could lead to bodily harm."
Hiro and Autumn made it through the window. They looked around. The place seemed dark. They heard Baymax try to get in, but he got stuck. "Oh, no." He said.
"Shhh!" Hiro hissed.
"There might be someone in here, a bad guy if I guess." Autumn whispered.
"Excuse me while I let out some air." Baymax said. He let out some air, which made a high-pitched noise every now and then. Hiro then pulled Baymax through. It took him a little bit to re-inflate.
"Keep it down." Hiro warned. He and Autumn went down a flight of metal stairs. They saw a conveyor belt putting microbots into trash cans. "My microbots…?" Hiro said in shock.
"Someone's making more." Autumn added. She and Hiro saw a symbol of a red bird. Before they could take a closer look at it, Baymax spoke up. "Hiro? Autumn?"
They jumped and turned around. "You gave me a heart attack!" Hiro said.
"My hands are equipped with defibrillators. Clear." Baymax proceeded to shock Hiro's heart, but he stopped him. "It's just an expression."
Suddenly, the microbots rose out of the trashcans. "Oh, no." Baymax said again.
"RUN!" Hiro and Autumn yelled. They realized Baymax was behind. "Come on!" Hiro whined.
"I am not fast." Baymax said.
"Yeah, no kidding!" Hiro exclaimed, pulling on the robot's arm.
They ran into the locked door. "Kick it down!" Hiro ordered. Baymax tried, with no luck. "Punch it!" Baymax punched the door, but it didn't work. That earned a groan from Hiro.
Hiro, Autumn and Baymax continued to run from the microbots. They crawled through a hole and were thrown onto a bridge. They saw the person responsible for controlling the microbots: a man dressed in black wearing a kabuki mask.
The Hamada twins nearly escaped with their lives, with the help of Baymax, who held the twins in his balloon arms, shielding them from a bad injury.
Shocked by the attack, Hiro and Autumn decided to report the incident to the police.
"All right, let me get this straight." Sergeant Gerson said. "A man in a kabuki mask attacked you and your sister with an army of miniature flying robots."
"Microbots." Hiro corrected.
"Microbots…" Sergeant Gerson said, typing in the issue.
"Yeah," Hiro went on. "He was controlling them telepathically with a neurocranial transmitter!"
"So Mr. Kabuki was using ESP to attack you two and balloon man." Sergeant Gerson realized.
Baymax took some tape and taped the holes he was getting.
"If we don't alert the public now, everyone could be in danger!" Autumn said.
"Baymax was with us!" Hiro said. "Tell him!"
"Yes, officer." Baymax said. "They're telling the…"
Baymax began to deflate and sway on his feet.
"What's wrong with you?" Hiro asked.
"Looooooow battery." Baymax said.
"Oh…" Autumn groaned. "Of all times, he had to have a low battery now."
"How about we call your parents and get them down here." Sergeant Gerson said. "What?" Hiro exclaimed.
"Write your names down and we'll get to you as soon as…"
But they were already gone. Outside, Baymax was saying a bunch of stuff he was programmed to say.
"We need to get him to his charging station, and fast!" Autumn exclaimed.
Soon, it was dark. Hiro and Autumn got Baymax home.
"If our Aunt asks we were at school, all day, got it?" Hiro asked.
"We jumped out a window." Baymax said.
"No, no, quiet! Shhh!" Hiro hissed.
"Shhh! We jumped out a window." Baymax whispered.
"Don't say things like that when we're around Aunt Cass!" Hiro whispered.
"We must stay quiet, or Aunt Cass will be in our beeswax!" Autumn quietly added.
Baymax shushed himself and Autumn nodded, giving him the thumbs up. Hiro and Autumn tiptoed up the stairs. Baymax tripped. He shushed himself again, this time, Hiro nodded and gave him the thumbs up.
"Hiro? Autumn?" Cass called. "You home sweeties?"
"Yes, Aunt Cass!" Autumn called.
"Uh, that's right!" Hiro replied.
"I thought I heard you." Cass turned to face her niece and nephew.
"Hey, Aunt Cass." Hiro said sheepishly.
"We love you, Aunt Cass." Autumn said.
"Look at my little college man and young woman." Cass began to cry tears of joy. "I can't wait to hear all about it! Oh, wings are almost done." she turned away.
"Whee!" Baymax squealed. "Will you be quiet?" Hiro whispered. Thinking it was Hiro who said it, Cass replied, "I know, whee!"
While Cass's back was turned, Hiro and Autumn went up the next flight of stairs shoving Baymax. "Get ready to have your faces melted! You're gonna feel these things tomorrow, know what I'm saying? Ok, sit down and tell me everything." Hiro and Autumn came back down.
After some more chit-chat with their aunt and getting their supper, Hiro and Autumn went upstairs to their room and found Baymax petting Mochi. "Hairy baby." He called the cat. Hiro guided Baymax to his charging station.
"Tadashi." Baymax said, noticing Tadashi's absence. "Tadashi." He said again.
"Tadashi's gone." Hiro replied.
"When will he return?" Baymax asked.
"He's dead, Baymax." Hiro answered, closing Tadashi's divider.
"Tadashi was in excellent health." Baymax said. "With a proper diet and exercise, he should have lived a long life."
"Yeah." Hiro agreed. "He should have."
"But there was a fire. That's one of the things I'm afraid of now." Autumn added.
"Tadashi is here." Baymax said.
"No." Hiro objected. "People keep saying he's not really gone, as long as we remember him."
"Tadashi was such a great brother." Autumn said. "Hiro and I both miss him so much. Annie is also dead."
"Annie?" Hiro asked.
"My Raggedy Anne doll. Mom gave it to me when I was two. She was buried with Tadashi." Autumn replied.
"It still hurts." Hiro said.
"I see no evidence of physical injury." Baymax said.
"It's a different kind of hurt." Hiro replied.
"He means emotional pain, Baymax." Autumn added.
"You two are my patients. I would like to help." Baymax said.
"We can't fix this, buddy." Hiro said sadly.
"Tadashi's gone, Annie's gone, and so is Professor Callaghan." Autumn finished.
Hiro noticed Baymax doing something. "What are you doing, Baymax?" He asked.
"I am downloading database on personal loss." Baymax replied.
Baymax then contacted Fred and the others, despite Hiro's objections.
Autumn smiled sadly. At least she would get to see Wasabi again.
Baymax then enveloped Hiro and Autumn in a comforting hug. "Other treatments include compassion and physical reassurance." Autumn sighed.
"You will be all right." Baymax said, patting the twins' heads. "There, there."
Hiro and Autumn returned the robot's hug. "Thanks, buddy." Hiro said.
"I'm sorry about the fire." Baymax said.
"It's ok. It was an accident." Hiro said.
"Or maybe it wasn't…" Autumn added.
Hiro looked at his microbot, picked it up, and examined it. "At the showcase, the guy stole my microbots and set the fire to cover his tracks. HE's responsible for Tadashi."
"We have to catch that guy and bring him to justice." Autumn declared. "But how…?"
She and Hiro looked at Baymax. They had an idea.
