Hiro tossed and turned in his sleep. His trauma-riddled brain was trapped in multiple nightmares at once. One minute, he's watching his brother burn to death in the SFIT explosion. Then he's dangling from a cable above Callaghan's portal, hanging on for dear life as multiple saw blades hack at his arms until he just can't hang on anymore. He falls through the portal into a universe where Callaghan killed all his friends; Wasabi was crushed by two concrete slabs, GoGo was suffocated in a sphere of microbots, Fred had all of his limbs ripped off, and Honey Lemon was stabbed by a giant spike of microbots while hiding in a pink dome made from various chemicals. Baymax's armor was in pieces, his vinyl body ripped to shreds and showing the carbon-fiber skeleton beneath. Callaghan shoots a wall of microbots at Hiro, then everything goes black.
Hiro yelped as he shot upright in bed, clutching the bandage covering his throbbing injury. Sweat rolled down his forehead, his dark hair clinging to his skin. He looked around the dark hospital room, illuminated only by the moon showing through the thin curtains.
"Hiro!" GoGo said softly from the chair she'd been sitting in a few feet away. Aunt Cass was curled up in the one by the window, sound asleep with a blanket on her legs. The others had gone home a few hours ago; they tried to convince GoGo to come with them, but she'd refused to leave Hiro's side.
Hiro glanced over at GoGo as she came over and sat on the edge of the bed by Hiro. "What's wrong?" she whispered. "Are you okay?"
Hiro nodded. "I-I'm fine..." he whispered back. "J-Just a nightmare. Well, more like three nightmares rolled into one."
"Are you in pain?" GoGo asked, noticing the way Hiro cradled his injured arm. When Hiro seemed confused, GoGo nodded towards the aforementioned injury.
Hiro followed GoGo's gaze and nodded slightly. "Just a bit...it's not unbearable though. I think I can handle it." But GoGo was already looking through the tray of medicine that Hiro's nurse had left on the table, trying to find the pain relievers she knew the nurse had brought. "GoGo, it's fine, really...you don't have to do that..."
"Hush," GoGo scolded, locating the pain medication and pulling out a small pill. "You should know better not to argue with me." She walked over to the sink at the other end of the room and filled a small glass with water. When that was done, she brought the glass and small pill over and set both in Hiro's hands. After he'd taken the pill, she helped him drink the water, since his left arm was all but useless and his right was shakier than a leaf in the wind.
"You didn't have to do that..." Hiro mumbled.
GoGo lightly punched Hiro's shoulder. "You needed it, and you know it."
Hiro rubbed his shoulder, wincing slightly since the motion involved moving his bad arm. GoGo gently wrapped her arm around him, pulling the boy close to her. "Just relax," she said softly. "You're alright, it's okay."
"You know," Hiro looked up at her, "I didn't think you were the comforting type."
GoGo snickered softly. "Ever heard of the phrase 'don't judge a book by its cover,' genius?"
Hiro smiled and rested his head on Gogo's shoulder, closing his eyes. She adjusted herself on the bed, pulling Hiro into her lap. She wrapped her other arm around him and held him close.
Hiro sighed. "I'm sorry."
GoGo pulled back slightly to look at him. "Sorry for what?"
"For everything. You all could have died. Baymax is gone because of me. Tadashi is gone because I let him go in that stupid burning building!" Hiro's eyes started to brim with tears and his breathing quickened with barely controlled sobs.
"Hey, hey," GoGo pulled Hiro right back into the hug, holding him close as he let go of all the emotion he'd been holding onto. "It's gonna be alright, Hiro. I promise."
Hiro clung to GoGo, gripping the 18-year-old's biker jacket tightly in his fist. Right now, she was his anchor, the thing he clung to when reality was pushing him over the edge and he needed something to hang onto. He'd never say it out loud, but he'd fallen in love with GoGo, despite the four year age difference. But he knew better than to tell her unless he wanted a punch in the gut.
"Thanks, GoGo," Hiro said softly, relaxing in her arms.
GoGo smiled softly. "Of course, genius."
Hiro closed his eyes, nestling his face in the crook of GoGo's shoulder. Together they lay back in the bed, GoGo still with her arms around her little hero.
"Don't leave me..." Hiro whispered as sleep began to overtake him.
GoGo kissed the top of Hiro's head, gently rubbing his shoulder. "Never."
A/N: Whoo! Finally finished this oneshot! This should be the final part, unless you guys want me to add an epilogue. But for now, that's the end of this little headcanon/oneshot! Next up on my list: Stalka fanfic.
