"Professor Callagahn!"

The group stands on top of a nearby building where Callagahn was forcing Krei to watch the new SFIT building be destroyed. Nina stood on her hoverboard, flying in place besides Hiro who demanded Callagahn to let Krei go. Callagahn turns to him with an angered look.

"Is this what Abigail would've wanted?" Hiro questions.

"Abigail is gone!" Callagahn answered.

"This won't change anything." Hiro shakes his head. "Trust me, I know."

"Listen to the kid, Callagahn." Krei speaks up. "Let me go. I'll give you anything you want!"

"I want my daughter back!" Callagahn puts his mask back on and outstretches his left arm causing microbots to fly in that direction right where the gang were standing. Nina quickly flew above the mirobots while the others ran away.

"Go for the mask!" Hiro exclaims, getting on Baymax while putting his helmet on. Baymax takes off towards Callagahn once Hiro was in place, but Callagahn moved out of the way before he could get hit.

He shot some more microbots at Hiro and Baymax, attaching the microbots to Baymax's foot and swings them into the side of the SFIT building. Nina's eyes widen, noticing Hiro crash through the windows of one of the rooms. Some microbots grabbed Baymax and threw him on the ground. Nina realized that the portal above the SFIT building was pulling everything inside which meant Hiro was also being pulled inside the portal.

While the rest of the gang jumps at Callagahn and try to get the mask Nina flies over to where Baymax was at, dodging microbots that were shot at her. She manages to get near Baymax and unharmed. She presses a button on her new and improved watch and aims it at the microbots keeping Baymax captive.

A laser beam shoots out of the end of a opening on the watch towards the microbots, slicing them apart and freeing Baymax. She made the watch be able to shoot a laser beam that could cut through anything. Her old watch could only send a small laser beam to zap whatever she aimed at. She decided to remake the watch and add some improvements to it. The new and improved watch was a secret project she has been working on in her free time that she didn't tell anyone about because she wanted to make it just right and not get anyone hopes up if she couldn't make it.

"Thank you, Nina." Baymax told her and she smiled. "No problem, buddy."

She could hear the others saying that Callagahn couldn't be beat and she glanced over her shoulders, frowning when she saw each of them were trapped. Could they really be giving up?

Then she hears Hiro over the intercom on her helmet which connects to the intercoms in the other's helmets. "Listen up. Use those big brains of yours and think your way around the problem. Look for a new angle."

"Baymax, we gotta go save Hiro." Nina said to Baymax. She then looks where Hiro was holding onto a loose wire, trying not to be pulled into the portal. Baymax then does a rocket fist and takes off flying towards Hiro.

Nina smiles once Hiro is back on Baymax and she goes to fly right beside them. "Glad you're okay!"

Hiro smiles back at her. "Yeah, you too! I saw the laser beam from your watch. That's new?"

"Yeah. Been working on it." Nina replied with a proud smile.

"It's pretty sick." Hiro complimented, looking back at her with a toothless grin.

Nina ignores the butterflies she feels in her stomach and grins at him. "Yeah, I know."

They fly back down to where the others were standing and then they all start heading towards where Callagahn and the microbots are. "Okay, new plan. Forget the mask. Take out the bots! They'll get sucked up into the portal."

"Now, that's a plan!" Wasabi exclaims.

Honey and Fred then give them some cover by doing a smoke freeze causing Callagahn to go up higher so he could see. Hiro and Baymax went towards the mask as Callagahn shoots microbots around them, but they manage to fly around them with some help from Nina using her laser beam on her watch. The microbots followed Hiro and Baymax towards the portal and at the last minute they dive down and break the microbots into pieces, letting them be sucked into the portal.

As Hiro and Baymax keep breaking the microbots, Nina shoots the laser beam at the ones that were left behind. Nina manages to dodge the microbots that were flown at her just in time as she notices Callagahn has got a hold on Hiro and Baymax right in front of the portal. She stays off to the side, watching with worry, not really knowing what to do.

"This ends now!" Callagahn yells, pushing his arms forward, thinking more microbots will come, but is confused when none show up. He keeps trying, but nothing happens and Nina smirks, happy to know that they won.

"It might help if you weren't out of microbots." Nina spoke, flying in place beside the portal.

"What?" Callagahn looks down at the ground where no microbots were. The only ones that were left are the ones he stood on and the two sets that kept Baymax in place.

Baymax then easily breaks out of the microbots' hold. The microbots get sucked into the portral while Hiro and Baymax fly towards Callagahn with Baymax's fist outward. For a second there, Nina thought they were actually going to hurt Callagahn. Right before Baymax would've hit Callagahn, he stops.

"Our programming prevent us from injuring a human being." Hiro stated, glancing over his shoulder when he noticed Nina flying over to them and they share a smile.

Nina flies over to Callagahn, taking his mask and hands it to Baymax to let him break it. "Yeah, we'll take that. Thanks."

The all the microbots break apart causing the portal and Callagahn to fall. Baymax catches Callagahn and the four of them fly back to the ground where the others were at. Nina jumps off of her hoverboard, pressing the button on the side of it to turn it back into a cube and puts it in her pocket. Baymax drops Callagahn on the ground as he lands and Hiro gets off of Baymax, standing beside Nina.

They turn around to look at the portal behind them that was still going. "That's not good." Nina muttered.

Hiro nods. "Yeah, it's still on. We have to shut it down." He said, turning to face the others along with Nina. "We can't! The containment field is failing." Krei explained. "The portal is gonna tear itself apart."

"I take that as a cue to leave." Nina says, looking at her friends who nod in agreement. They all start running away from the portal, but stop and look back when they realized Baymax wasn't with them.

"Why is he staring at the portal?" Nina furrowed her eyebrows, watching Baymax with confusion.

"I don't know." Hiro shook his head. He runs over to Baymax. "Baymax!"

"My sensor is detecting signs of life." Baymax stated. He points to the portal. "Coming from there. The life signs are female. She appears to be in hyper-sleep."

Nina's eyes grow wide, her lips curving upwards, glad that Abigail was still alive. Maybe there was a way they could save her. "Abigail."

"Callagahn's daughter." Hiro added, glancing back at her. "She's still alive."

Callagahn looks over at the portal with a longing expression. "Abigail."

Hiro then runs over to Baymax and gets on him. "Let's go get her."

"The portal is destabilizing. You'll never make it." Krei said to him which made Nina's nerves grow.

Hiro looks back at everyone. "She's in alive in there. Someone has to help."

A small smile made its way to Nina's face at the last sentence he said, making her remember the time Tadashi said that to her and Hiro. The smile then fell when she remembered Tadashi died right after he said that and she doesn't know if she could be okay without having Hiro in her life.

"Hiro." Nina gains his attention, looking at him with worry. He sends her a reassuring smile. "I'll be okay. Don't worry."

She's worried about what is going to happen, but she nodded her head while she bit her lower lip. Honey stands beside her and wraps an arm around her shoulder in a comforting manner as Hiro and Baymax fly into the portal.

It seems like it has been hours since the two have been in the portal even though it has only been a few minutes. At one point Nina and the others had to hide behind a block of debris from the SFIT building because the portal was getting so strong. The longer she had to wait, the more anxious and worried she got. Nina peeks over the debris along with her friends to look at the portal and they share worried looks with each other.

A few minutes later have past and they look over the debris when they hear a loud explosion and see that the portal had broke. Nina let out a sigh of relief when she saw Hiro on top of Abigail's pod.

"Hiro!" Wasabi yelled, getting Hiro's attention. Nina grins as she runs towards Hiro along with her friends.

"Yeah! They made it!" Fred exclaimed.

Hiro slides off the pod, looking at them with a sadden expression and that was when she saw Baymax wasn't with him. "Wait...where's Baymax?"

Hiro didn't say anything as he shook his head in response which caused her lips to curve downwards into a frown. The gang all had equally upset expressions on their faces while Hiro looks through the window at Abigail who's asleep.

The gang had eventually called the police and an ambulance to take care of Professor Callagahn and Abigail. The six of them now stood on top of a nearby building, watching everything happen below them, still upset for the loss of their robot friend.

****

It was finally the first day of Hiro going to SFIT. The gang were all excited about it and they decided to head to school together. Nina sat between Gogo and Fred at Lucky Cat Café. On the tv, the news were talking about the event with Professor Callagahn and a group of unknown heroes.

"Hey."

Nina looks up from fiddling with the watch on her wrist and a smile formed on her face at seeing Hiro. "It's about time you showed up."

"Yeah, we were waiting for you, slow poke." Gogo said to Hiro.

"Sorry." Hiro apologized.

"Ready to go?" Nina asks him and he nods. "Ready."

Nina gets up and puts her backpack over her shoulders while the others get up. The gang heads towards the door, conversing with each other. Nina stops when she realizes Hiro hadn't followed them yet. She turns around, smiling at seeing him and Cass hugging.

They pull away from the hug and Cass hands Hiro his lunch. They both go to turn away before Hiro suddenly turns back to Cass and hugs her. "Last hug."

Cass looks surprised, but smiles and hugs him back. Nina smiles at the aunt and nephew duo while the two pull away from the hug. Cass points at her. "You. Get over here. I want a hug from you, too."

Nina giggles a bit and heads over to her, giggling more when Cass pulls her in for a bear hug. "Take care of Hiro for me, okay?"

"You know I will, Cass." Nina replied, pulling away from the hug and they share a smile.

"Come on, they're waiting for us!" Hiro told her. Nina let out a surprised yelp when he grabs her hand, ignoring the way her heart flutters as he pulls her towards the door. "Okay, I guess we're leaving."

Cass chuckles at the two, thinking they are a good pair. Cass waves back at Nina and Hiro before they leave the café.
