A/N: OKAY so you know how in big hero 6 the series (season 2!) Hiro gets those magnet glove things? He uses them for the first time on the bridge and basically just uses them to trap villains and climb and jump and shit. That's what Rena has! Exactly what she has! Except instead of fancy magnets or whatever it's just slime or plasma or something so she can stick to stuff! (I didn't steal that from the series I literally just finished watching S2 today and ahhh oh my god the finale had me crying tbh.)

I fell out of love with writing for a bit but ever since going back to school I've realised how calming it is to be writing shit that's not for academic purposes. Also I love these characters with my whole heart and they're so fun to write with. I really love their chemistry ahhh.

SO a bit of a time skip in this chapter cause I got bored of hospital chapters lmao. As always, enjoy but also please review or DM me your thoughts! I genuinely love hearing about what people have to say about my dumb little fic! :)))

It had been exactly two weeks since the cafe had been robbed. Rena, Hiro and Tadashi were sat on the floor in Hiro and Tadashi's room. Rena had been let out of the hospital a week before, much to her delight. She was finally able to get back to SFIT and stay at home.

The cafe had been repaired. The damage was extensive, but luckily due to their insurance it was fixed rapidly. Everyone was still a little shaken up about what happened, and the SFPD had not yet managed to apprehend the criminals that did it. Nevertheless, the Hamada siblings were trying their best to remain positive.

'Where's the pencil sharpener?' Rena asked, staring at the many scribbled she'd made on the paper. 'I think I've made a miscalculation.'

Tadashi passed it over without a word and she sharpened it quickly. She drew a neat line over a line of calculation and sat back, chewing the end of the pencil thoughtfully. 'Christ, why does robotics involve so much math?'

Tadashi didn't respond, he was so deeply immersed in his laptop that Rena doubted he even heard her. Hiro lent over her shoulder and pointed to an equation.

'You need to square that. And then do this... yeah... add that to that... square root it... divide this by 4...'

His hand flew over the page and the problem Rena had been struggling with for the past half an hour was solved in under a minute. 'OHHH I get it now! Christ, how'd you do that so fast?'

Hiro grinned. 'I like maths.'

'Can't say the same.' Rena sighed, placing the paper to the side and stretching. 'Boring subject to be honest. If it weren't for the fact that I need to take it, I would've been rid of it years ago to be honest.'

'I feel the same about English.'

'Writing's fun! You're just boring.'

'Yeah yeah. Whatever.'

Hiro adjusted his sling before grabbing another textbook from the huge stack and began frantically scribbling in another notepad. 'Oh, I ordered the stuff we needed for Baymax a couple of days ago by the way. I covered the money though, you don't need to worry about it.'

Rena stared at him. Even Tadashi looked up from his work to gawp at their little brother.' 'How... how did you manage to cover it? Didn't it come to a few hundred dollars?'

Hiro shrugged, his cheeks slowly going red. 'Oh! I had uh... I had some money saved from a while back.'

Tadashi squinted at him suspiciously. 'How much? You said you spent it all on that new computer.'

'Oh... not ALL of it...'

Rena's mind drifted back to the death threats. They'd been plaguing her mind for the last couple of weeks, but neither her nor Tadashi had told Hiro. They hadn't even had a chance to discuss it with one another, mainly due to the fact that Rena was trying to avoid thinking about it. She knew it had a connection with how she had almost died, but the idea that this was linked to Hiro was hard to swallow.

She gripped his non-injured hand. 'Please tell me you're not botfighting. Please.'

'Wha... No! Where'd you get that from? Of course I'm not!' Hiro spluttered, pulling his arm away from her.

'Then where's the money from?' Tadashi asked, attention now completely away from his computer.

'I already told you! I had it saved! Can we please stop talking about this?'

Tadashi gave Rena a Look which she translated in her mind as 'we need to investigate' but for now decided to drop it. 'Okay fine. We need to be at SFIT soon anyway, I told Gogo we'd be there before seven.'

Tadashi reached over and grabbed his prosthetic. 'Well, might as well get going now then. Baymax still has a lot of work that needs doing!'

Rena tossed her homework to the side and stood before helping Tadashi to his feet. 'I'm already dying of excitement.'

'You are going to clean that up right?' He asked, gesturing to her discarded books on the floor, 'this isn't your bedroom.'

'Yeah, yeah I'll do it.'

Tadashi was still fiddling with his leg when Hiro had grabbed his hoodie and darted off down the stairs. Rena stood and waited for her brother. Tadashi straightened out and as she turned to leave he grabbed her wrist.

'Rena. He's doing it again isn't he?'

Rena swallowed anxiously, her eyes drifting towards the stairs. Knowing Hiro, he was probably crouched there listening in to their conversation. Suddenly, an image flashed in her mind. She was crouching in the bathroom cupboard, searching for antiseptic. She blinked and the image moulded to Hiro stood in the doorway, a wild look in his eyes and blood dripping down his leg.

'I... shit.' She muttered under her breath. She was so out of it she hadn't thought to make the connection until now...

'What?! What is it?'

He'd been botfighting. Clearly. How had she not thought about that until now? Her mind had been so preoccupied it had completely slipped from her head. Of course he was botfighting!

The only question was why. Was SFIT not enough for him? Was he just bored? Or was there something else going on? Either way - she had to find out. For his own safety.

'He's definitely botfighting. I...' She paused, uncertain whether or not to tell Tadashi. However, she realised that he'd probably kill her if he ever found out he kept that from her. 'Remember like... the night I got... uh... poisoned? Yeah well... I woke up and he had come back in the house. His leg was bleeding... but I was too out of it to make the connection. I... I completely forgot.'

Tadashi's face went white. 'Oh.' He whispered quietly. 'We have to do something!'

'GUYS? You coming?' Hiro yelled up the stairs.

Rena jumped. 'Yeah! In a sec!' She called back down. She turned back to Tadashi, twirling a strand of hair around her finger. 'There has to be a reason!' She hissed, 'I... let's follow him. When he next goes out.'

Tadashi nodded, face determined. 'Yeah. Then we can confront him.'

Rena didn't like it, but she didn't want to accuse her little brother of doing something when he might not be after all. 'Yeah. Okay.'

Rena sat on the edge of Honey Lemon's desk, holding a stopwatch and peering closely at a conical flask for her.

They were at SFIT - all of them. The friends hadn't had much chance to see each other in the past few weeks, especially seeing as most of them were a little worse for wear after the incident at the cafe.

Fred was lounging on one of the couches as usual, a bandage around his shoulder. Wasabi had a line of stitches running across one arm and a cheek, and Gogo had been on crutches much to her fury. Hiro still had his arm in a sling and Tadashi had a bandage around his arm as well. Honey Lemon had broken her collarbone. However, the team were still in positive spirits and were all determined to put the incident behind them. Well, apart from Fred, who was still giving his wild theories on who could have been responsible.

'... Yeah but... what if it was Krei this time? I'm being serious!' He added loudly as Gogo laughed at him from her corner.

'Yep Fred,' she said, sitting on the side and tapping on her laptop, 'it's definitely Krei. Yep, because there's tons of benefits of sending a load of armed robbers to a tiny cafe!'

'Gogo's right.' Rena said, 'just give it up Fred. Honey, this is done now.' She handed the timer back to the taller girl and strolled on over to Fred before collapsing onto the couch beside him.

'Thanks Rena!' Honey Lemon called, scribbling some numbers down into a notepad.

'Don't you have some work to do?' Wasabi asked Rena dubiously as she sat back and pulled her phone out from her pocket.

'Maybe.' She replied, sighing. 'Eh, I'll do it later. Besides, I came to help with Baymax.'

'Then you could come help!' Tadashi called from the corner. He was crouched awkwardly on the floor next to a huge pile of parts, tools and bolts. Hiro was in the very far corner of the lab, soldering together some circuits.

'In a minute!' She called back, logging onto Twitter. Her feed was flooded with rainbows and pride flags. She sighed and clicked off the app almost immediately.

It wasn't like she was scared of how everyone would react when she came out. She knew deep down that everyone would be fine with it. Rena didn't know what was holding her back - but in that moment she thought she'd rather drink a bucket of cold sick than come out to all her family and friends.

'Okay, Rena. Listen - the robber was Yama. Wanna know how I know?' Fred asked enthusiastically as soon as the conversation died.

Rena snorted. 'Yama's like the size of a house. Would be even be able to fit through the door?'

'Oh yeah? Hiro was terrified when he walked in - the little guy dropped a glass on the floor as soon as they were at the counter.' Fred said smugly.

Rena sat up straighter, her mind whirring. So it was connected to Hiro. The cafe. The death threat. It all linked back to botfighting -it had to. Surely. There was no other logical reason that her family would be threatened with death. 'Are you sure about that last bit? Absolutely positive?'

Fred nodded. 'Yeah! 100%!'

She sighed deeply. 'O... okay. I don't think it has a connection though... he was probably just scared.'

Fred didn't seem to be disheartened. 'Yeah well, I have a hundred other ideas so...'

'Great! Tell me later!' She said quickly before practically jumping out her seat and running over to her older brother.

She crouched down next to Tadashi and dropped her voice to a whisper. 'It's gotta be connected. All of this. We need to find out what's happening - and fast. Before anyone else gets hurt.'

Tadashi nodded, his face grave. 'We need answers. And we also need Baymax.' He nodded to the pile of materials that had collected on the floor. 'All the more reason to get this done as quickly as possible. I could finish the actual bot within a couple of days with Hiro's help. It's just the chip that's slowing us down.'

Rena nodded. 'Yeah. We definitely need Baymax before anything else happens. What do you need me to do?'

Tadashi considered for a moment. 'There's a black leather notebook on the desk in my lab. I'm also gonna need my laptop. If that's okay with you. I'd go myself but...'

He gestured to where his prosthetic was lying on the ground. Rena nodded and got to her feet. 'Okay. Fine. I'm going.'

She practically ran to Tadashi's lab, the importance of finishing the robot now the only thing on her mind. She flicked the lights on and scanned the room for the notebook.

'Black notebook... black notebook...' She muttered to herself. She backed away into the corner, rifling through a heavy looking stack of books on top of a filing cabinet.

Rena turned around, her leg smacking into something hard. She swore loudly before realising what it was. Baymax's old rocket fist. She smiled weakly and patted the side.

'Not long now buddy... not long now.' She whispered. As she did so, something caught the corner of her eye. Something green. Rena blinked in surprise and pulled back the robotic fingers to reveal...

'The chip!' She exclaimed in glee, not caring that she was yelling this to an empty room. She could've danced with glee. This might be the thing that could prevent anything else from happening to anyone! They could be safe!'

She scooped it up quickly and switched off the lights, running as fast as she could back to the main lab. Her shoes squeaked noisily on the floor but she could barely hear it over her own panting. Technically, she wasn't allowed to run at all. Doctor's orders. In her excitement though, she had completely forgotten.

By the time she reached the lab, there was no air left in her lungs. She kicked the door open and burst in, hands on her knees and panting.

'I've... got! The...' She gasped.

Someone's hand was on her back. Honey Lemon. 'You okay?' She asked kindly, eyeing Rena with concern.

'Yeah!' Rena breathed, walking unsteadily over to Tadashi.

'Damn you're really unfit.' He said, laughing. 'Hang on, did you even grab the stuff? Honestly I...'

He trailed off mid sentence as Rena held the chip victoriously in the air. 'Look what I found!' She exclaimed, grinning.

From behind her, Honey Lemon gasped and Fred let out a celebratory whoop. Tadashi stared, speechless at the tiny green chip his sister was brandishing.

Then, he sprang to his feet and tackled her with a hug, momentarily forgetting that he could barely stand on his own. The pair of them came crashing to the floor with a yell of surprise then a quick shriek of laughter.

'Get off!' Rena gasped, pushing him off her. Tadashi rolled away, grinning. He snatched the chip greedily from her outstretched hand and ran his fingers along the smooth surface, examining it.

'I can't believe it.' He whispered in awe.

'Baymax must have left it for you.' Honey Lemon said, grinning hugely.

'Got to hand it to you,' Gogo said, hobbling over on one crutch, 'pretty impressive coding.

'Yeah.' Rena said, grinning to her brother. 'It was.'
