TADASHI

I wake up in a small, dark room sitting in a chair. My head hurts. I bet I banged it on the computer when I got knocked out.

I try to move and wince as rope cuts into my skin. Everyone complains about people using too much slack, but I think it's the opposite in this case. The ropes around my ribcage are so tight I think they're constricting me. It's hard to breathe.

A door at the other end of the room opens and a familiar figure walks through it. My eyes narrow as the man Hiro calls Obake approaches me.

"And what do you want?" I ask belligerently as he comes to a stop in front of me.

He grins. "Careful, Mr. Hamada."

I scowl at him. The only other person who called me Mr. Hamada was Professor Callaghan, and he killed me. Essentially.

"So, Mr. Hamada." Obake pulls up a chair and falls into it. "I am working on a new piece of technology, one that is nearly finished. I simply need to know one thing and my plans will be put into full operation. So tell me. Where will Hiro Hamada be at eleven o' clock this evening?"

I clench my jaw. "You seriously think I'm going to answer that."

"Yes, I do."

"Why, exactly?"

"Right now, I have power you can't imagine and likely don't want to. So I suggest you answer me now, before things get ugly. I would hate to be responsible for any injuries you had sustained."

I feel the color drain from my face. "I'm not telling you anything about Hiro."

"That would be unwise, Mr. Hamada."

I roll my eyes. "You can stop being cryptic. I get it, you'll torture me if I don't tell you what you want to know. It's sort of obvious. So you can drop the act."

Obake's mouth quirks to one side. "Very good, Mr. Hamada. You are intelligent…perhaps too much for your own good."

"I don't need flattery, or threats, or torture. I'm not telling you anything."

He breaks into a full smile. "I thought you were smarter than that."

The words ring in my head. The same words Krei said to Hiro when he was trying to get him to sell the microbots to KreiTech. The same words Callaghan responded to by manipulating Hiro into leaving his microbots in Callaghan's hands, leaving Callaghan free to set the fire and get out unharmed. The words that, ultimately, led Hiro to fall into depression and nearly commit murder.

I study the copper cuffs on my wrists, trying not to think about what Hiro did to himself after I died. Almost got back into illegal bot fighting. Pushed away his friends. Starved himself. Refused to let Baymax help him.

Refused to let anyone help him.

I push the memories away, concentrating on the cuffs. I wonder what they're for. They must have a use, but they're not connecting me to anything. All I know is that copper is in group Ib of the periodic table, its atomic number is twenty-nine, it's a great electricity and heat conductor, and its density is eight-point-nine-six grams per centimeters cubed.

I stop. I know a lot about copper.

Obake's grin widens. "I've taken a liking to you, Mr. Hamada. I don't want to hurt you. But if that is what it takes, I will."

"Fine." I lift my chin. "Do it, then."

"Very well."

Obake crosses to a mechanism on the wall and turns a small knob for a few moments. He presses a button beneath it.

The cuffs on my wrists spark to life, crackling with electricity. It travels up my arms and through my body, filling me with a fiery, burning pain. I don't realize I'm screaming until the pain fades, not as bad but still there.

"Well, Mr. Hamada?"

I grimace at the lingering pain, but my jaw remains clenched. "I'm not telling you anything."

"Pity."

His smile doesn't change as he presses the button again.

The pain is more intense this time, coursing through me like fire in my veins. I close my eyes, but the sight of Obake's cold, indifferent smile is burned into the inside of my eyes. I can't think, can't see even if I opened my eyes, can't hear anything but screams of pain echoing off the walls—

Someone is screaming.

My first instinct is that I have to help them. Then I realize it's me.

The pain dulls enough that I have control of my senses again, and I open my eyes. My face feels wet. It takes me a second to realize that tears are streaming down my face. Obake glances at me with his frozen smile, one eyebrow raised in an invitation to tell him everything and save myself.

"I won't—"

The electricity surges, and I scream again. Obake's expression doesn't change.

"No."

More pain. More screaming.

I know nothing about what he wants with Hiro, only that I won't give it to him. I will not give him the satisfaction of beating me.

And I will not let him hurt my little brother.

"Mr. Hamada." Obake comes forward until he stands directly in front of me. "You know this is useless. I will extract this information from you eventually. You cannot resist me forever; we both know that. Why not give up now? Save yourself all this time and pain? Just say the words, Mr. Hamada, and everything will be all right."

Baymax's voice echoes in my head as Obake presses the button and I start to scream again.

You will be alright.

But not to me.

Hiro.

Hiro.

My brother's name is the last thought in my head before I black out.

Hiro

As soon as Tadashi comes home, I know something is wrong.

He's not acting like himself. He throws his motorcycle helmet down and stomps inside, muttering to himself.

"Tadashi." I stand up from my spot on the couch. "What's wrong?"

"I'm fine," he says, not sounding very fine at all.

"Yeah, right."

"I'm fine, Hiro."

"You're not fine, Tadashi."

"I'm. Fine."

"Tadashi, what happened?"

"Nothing!"

"What was it?"

"Nothing, Hiro!"

"You're hiding something."

"No I'm not!"

"You are."

"I'm not."

"Tadashi, please. You can tell me. I won't judge."

"It's nothing!"

"Tadashi—"

He whirls around and shoves me against the wall. I gasp in both pain and surprise. Tadashi has never used physical force with me before—the worst he's ever hurt me is a playful punch on the arm.

He looks me in the eyes, and I know something is horribly wrong.

"I'm. Fine." Tadashi's eyes narrow into a glare as he steps back and lets me go. "Nothing's wrong."

"You're lying."

He slaps me across the face, so hard that it knocks me off balance and I fall to the floor, clutching my cheek. I hear the door slam behind him as he storms out of the house.

I push myself into a sitting position and video call Honey, Fred, and Wasabi. They all pick up immediately—probably thinking it's a superhero thing.

"Hiro! What is it? What's wrong?"

I stare after Tadashi. "I wish I knew."

"Listen up, guys," I say once everyone is gathered in the café. "I know we're not fighting a supervillain or saving the city, but we have to be superheroes now—maybe more than ever. Something's wrong with Tadashi. He's acting strange."

Wasabi breaks in. "So what you're saying is, Tadashi's out of his mind, you don't know where he is, and we need to find him before he does something stupid like throw himself into the ocean."

"I'm sure it's not that bad," Honey Lemon says hopefully. "I mean, he can't really be out of his mind, can he? Maybe he's just having a bad day."

"I think it's exactly that bad," I say. "I think Tadashi's out of his mind. Like, really out of it. As in it's not him doing all of this."

"Yeah," Fred says in awe. "He's a robot."

"No. Not a robot."

"Then what is it?"

"I think someone else is controlling Tadashi's mind."

Everyone gasps collectively. I pull up the tracking app for the GPS I installed in each of our motorcycle helmets.

"Guys." I search for the red dot that signifies Tadashi and my eyes widen when I find it. "He's heading for the bridge."

Honey gasps. "You don't think—"

I nod. "I think he might try to jump."

"We need a plan," Wasabi says.

"I don't think so," Fred puts in. "We follow our dear old Teddy Bear to the bridge and talk him out of jumping. That's all there is to it."

"It's really…not," Honey replies.

"Really? What else is there?"

"He's not jumping of his own free will," she explains. "If someone's making him jump, he'll jump. It won't matter what we say. We can't negotiate with him, so what we have to do is destroy whatever's controlling him."

Everyone stares at her. She fidgets uncomfortably.

"What?" she asks.

"That's…really good," Wasabi says.

She rounds on him, suddenly defensive. "What? I can't think up the plans because I'm a girl?"

"No!" Wasabi says, panicking slightly. "I think you're brilliant! It's just that I'm amazed you had a good enough plan to get all the way through it without Fred interrupting you. Even GoGo couldn't do that."

The atmosphere in the room darkens as everyone remembers GoGo, our friend who was brainwashed into betraying us and later gave her life for Big Hero 6. Controlled by a chip in the kabuki mask she was given and forced to attack us. Then she crushed her mask and triggered the explosion that killed her—but also Callaghan and Krei.

The sadness only worsens when I remember how close Wasabi was to proposing to her when she died—just like Tadashi and Honey Lemon, only reversed. And GoGo isn't going to come back.

"Wait!" Honey stands up from the table. "That's it!"

"What?" I ask. "What's it?"

"She was being controlled with a KreiTech chip in her mask, right? Dashi talked her out of it long enough to get the chip away from her mind, and then she was herself again. What if that's what happened to Tadashi?"

"You're a genius," Fred tells her.

Honey blushes. "It all makes sense, doesn't it? Tadashi works at KreiTech. Krei would have had easy access to him. And he had a long shift today—probably just enough time for Krei to put a chip in his brain. He could be controlling Tadashi, maybe luring Hiro to the bridge so he could kill them both. But he won't expect the rest of us to come too, so we can overpower him, knock him out so he can't control Tadashi, and bring Tadashi home."

Fred looks around. "No one else is saying it, so I'll say it again—you're a genius, Honey."

Honey blushes harder.

"Yeah," Wasabi says. "I admire your ability to think under a lot of pressure, given that it's yourboyfriend we're rescuing from Krei-assisted suicide."

All the color drains from Honey's face.

I glance down at my phone and see that Tadashi's location has stopped in the middle of San Fransokyo Bridge. I feel my face pale at least three shades.

"Guys—" I stand up. "We should hurry."

We hurry. Less than three minutes later, we are on the bridge with our various forms of transportation. Wasabi and I are on my motorcycle, Fred is using his Super Jump to get around, and Honey is using a pair of GoGo's electro-mag suspension roller skates. We're at Tadashi's location in minutes.

Tadashi stands at a section of the bridge with no railing, staring at the water.

Poised to jump.

"Tadashi!" I edge along the bridge, trying not to let the wind or the rain sweep me into the ocean. "Tadashi!"

He turns, and something flickers in his eyes before they turn hard and empty again. "Hiro?"

"What are you doing?" I shout over the wind.

Tadashi's eyes flicker again, and I realize that his irises are now a dark gray, the same shade as the water beneath him. His face is set in a tight grimace—he's fighting Krei's control, and his brain can't decide whether it should listen to Krei or Tadashi.

"Well, well," says a sinister voice from about ten feet away. "Big Hero Six."

I turn, and it's not Krei I see.

It's Obake.

"Obake," Fred says in his superhero voice. "It seems we meet again."

"It would seem so," Obake replies evenly.

"For the last time, it seems."

"Seemingly."

Fred glares at him, having run out of "seems" statements to throw out.

I turn my attention back to Tadashi, who is still poised on the bridge.

"Tadashi—"

"Hiro."

I stop. I feel Honey Lemon's hand on my shoulder, steadying me.

"It's better this way," Tadashi says softly. "Trust me."

"How?" I ask, my voice cracking. "Why? Why would you leave me like this?"

He looks back at the water. "I have nothing left to live for."

"Really?" Honey breaks in, stepping toward Tadashi. "What about Baymax? What about Hiro? What about—" Her voice cracks too. "What about me, Tadashi?"

Tadashi looks at her, and his eyes shift back to hazel for a moment. Honey slowly moves toward him, her eyes pleading.

"Please, Tadashi," she whispers. "Stay with me."

Tadashi's eyes flicker between hazel and gray. I step forward, placing myself somewhere I can at least try to catch him.

Honey Lemon intertwines her fingers in his and whispers, "Please."

He clasps her hand in both of his and presses her fingers to his lips before his eyes turn back to gray.

Then he turns toward the water and jumps.
