Winter had arrived to San Fransokyo, and the team decided to take a little skiing vacation to Fred's parents' mountain Chalet. Hiro had just bought a new snowboard and was more than happy to test it out.

"Race you to the bottom, again!" Hiro started running back up the snow-capped mountain, the others following close behind him.

"No fair!" Wasabi called up to Hiro as he ran ahead of the other teens.

"The snow's really starting to pick up," Honey pulled her scarf closer around her mouth.

"Yeah, but that's what makes it fun," GoGo dragged Honey by the hand and dragged her up with her.

"Ready?" Fred placed down his snowboard right beside Hiro's.

"I am," Hiro replied, As for the others? I don't know.

The others lined up and Hiro gave the countdown.

"3... 2... 1!"

The teenagers shot down the hill at high speed, Hiro jetting ahead of them. However, unknown to Hiro, a rock, that was square in his way, caught the front of his snowboard and he tumbled in the snow. He screamed in pain as he felt the force of his body twisting against the wedged snowboard, breaking his legs and hip, and the collision of his left shoulder colliding with the harsh stone of the mountain. He continued rolling at high speed, striking several sharp rocks, and then crashing into a tree.

"Hiro!" Honey slowed herself and quickly leaped from her skis, kneeling by his bleeding body, "Hiro! Don't be dead! Please don't!"

Hiro groaned weakly, unable to speak in his pain and Honey had to shush him and comfort him as the others gathered about.

"We need to get back to the chalet," Honey spoke shakily, unzipping her jacket and wrapped Hiro in it and lifting him up. Despite her lanky frame, she could be strong when she needed to be.

The teens made their way back to the chalet, Fred using his snowboard as a stretcher for Hiro and carrying him on it with Honey's help. when they got back, they rushed in and laid Hiro on the couch, Aunt Cass covering her mouth in horror and shock.

"Quick! Activate Baymax!" Honey ordered, but then realized he was only activatable by sounds of distress, "Ow!"

Baymax inflated in an instant.

"Baymax, scan Hiro," Honey spoke shakily. Luckily, Baymax understood and scanned Hiro in a second.

"Scan Complete!" Baymax spoke, "Hiro has broken both legs, shattered his left shoulder, broken his left arm, broken his hips, broken four of his lower left ribs and two lower right ribs as receiving multiple cuts, a large gash on his left side and a concussion. We must call a doctor immediately."

"Already tried," Aunt Cass fussed, carrying both the landline phone and her cell, "They can't get up here until the storm ends. We'll have to make use of what we have. Honey. take off Hiro's jackets. I'll grab the first aid kit."

Honey did as she was told and Fred quickly cleared the dinner table of the plates of food that was to be their dinner and laid a sheet on the table so Hiro could lay on it while they patched him up. Meanwhile, Wasabi carried Hiro in and GoGo helped Cass to bring in the first aid kit. Baymax started by spraying Hiro's cuts and gashes with disinfectant, which caused the unconscious teen to hiss in pain. Then, Aunt Cass worked on setting his broken legs before splinting and wrapping them in sterile white gauze. Meanwhile, Honey was wrapping Hiro's wounded abdomen and lower chest in gauze, helping to set his broken bones with Baymax's help. Fred had set Hiro's arm with some help from Wasabi and was now wrapping and splinting the arm while GoGo wrapped Hiro's forehead and shoulder until she was sure it was the best she could. Wasabi was wrapping Hiro's hips and making sure the others were setting their respective wounds properly. Finally, Fredd finished tying a sling for Hiro's broken arm and Baymax rescanned Hiro.

"Good," Baymax spoke, "Hiro's wounds have all been set, so he will make a full recovery. Now, we must let him rest."

"Oh thank goodness," Aunt Cass sighed and helped Wasabi to carry Hiro upstairs to his room. There, she tucked him in and knelt by his side.

The teens brought up the food and offered Aunt Cass her dish, but she was too worried, she couldn't even eat the food, despite her stress levels. They just sat about, waiting, praying Hiro would wake up. They remained there for several hours until he started to stir.

"Aunt Cass?" Hiro weakly spoke, exhausted and in extreme pain, "Wh... Where am I? What h... happened?

At this, Hiro tried to sit up, but a shot of pain from his broken ribs and hips caused him to grunt in pain. Aunt Cass gently pushed him back down so he wouldn't hurt himself anymore.

"Take it easy, Honey," Cass fixed his sling and pulled his blanket back over his chest, "You had an accident on your snowboard. You meed to rest."

"Okay," Hiro nodded, allowing her to stroke his hair, "Did anyone else get hurt?"

"No," Aunt Cass replied, "Everyone else is fine. they all helped to bandage you up."

"That's good?" Hiro smiled, turning his head to smile at his friends and chuckling at Baymax, who was stood on the other side of the bed, stroking Mochi in his arms.

"Hello, Hiro," Baymax greeted happily, "On a scale of 1 to 10, How would you rate your pain?"

"Like a 20," Hiro weakly smiled, "Nothing some rest can't help fix."

"Well, you can have a good sleep now," Aunt Cass stroked his hair, "You'll need it."

The other teens bid goodnight and Baymax set down Mochi and deflated into his case once Hiro claimed he was satisfied with his care. Soon, Mochi left too, leaving Aunt Cass and Hiro alone. Aunt Cass sat on the bed and kissed Hiro on the cheek.

"Night, sweety," Aunt Cass stroked his hair as he drifted off to sleep, "Sleep tight."

"Night, Aunt Cass," Hiro, pecked her cheek and closed his eyes, "I love you."

"I love you too," Aunt Cass replied and laid by his side, hugging him until she too drifted off to sleep.
