A/N: Hi guys! So I know it's been a while (sorry). I was in Disney! And I got so much BH6 merch while I was there and it's been inspiring me. Then I had my wisdom teeth removed which wasn't so inspiring…But you don't wanna hear about that. The idea of this fic came from a line I spotted in a San Fransokyo tour brochure that was included in a BH6 book in Barnes and Noble. Apparently San Fransokyo was destroyed by an earthquake (the same kind that often hit San Francisco and other areas of North California) and the city in the movie is on the cutting edge of technology deliberately as a result of the rebuilding efforts to make it that way. Well that got me thinking: earthquakes are pretty common in Cali, including big ones. What's to stop another earthquake from occurring? And I know buildings in San Francisco are over-engineered to handle the added stresses of earthquakes and it stands to reason San Fransokyo is the same way…but what if it was a REALLY bad earthquake that overwhelmed their infrastructure?

So this is set sometime after my fic "These Are The Things." For those of you unaware, all of my BH6 fics are on one continuous timeline so go read These Are The Things for more details! But long story short, Tadashi is alive. I'll allude to the previous story on occasion so it'll probably make more sense if you've read my other stories, but you don't need to. Also, thanks for all the prompts! Seems like many of you want more Tadahoney, more Hiro and Tadashi brotherly moments, Tadashi helping the team, and more Aunt Cass being her badass self so I'll see what I can do on those fronts and incorporate them here and future works! Please let me know what you think. (And apologies for the long ramble)

ALSO REALLY IMPORTANT: Most sources are saying Tadashi is 21 during the time of the movie events, so that's what I'm sticking with. I didn't just make that age up, I swear!

"Turn it down, we're trying to study!" GoGo practically snarled at Fred as a hyper-realistic explosion noise rang out from the television where he was playing his video game.

They were in Hiro and Tadashi's garage, studying for finals, which started the following week, and it was safe to say everyone was a little stressed. Tadashi had developed a disturbing caffeine dependence, Hiro couldn't sleep fitfully and stayed up late into the night studying, Wasabi was always teetering on the brink of a meltdown when faced with studying for his advanced linear algebra course, GoGo was moody, and even Honey Lemon was a lot less perky. Only Fred, whose final grades consisted almost entirely of essays and term papers that had already been turned in, was able to carry on as normal.

There was quiet for a few minutes, then suddenly another series of loud, cartoonish explosions and gunshots.

"FRED!" GoGo got up from her chair so quickly it fell over. Everyone seated around the table looked up, faces registering shock and even fright at the girl's sudden outburst. Even Fred, who was usually unfazed by GoGo's aggressiveness during finals week, looked afraid. He fumbled for the remote and turned the volume down as low as it would go without breaking eye contact with her for fear she would strike without him seeing. She paused, waited until she was sure he wasn't going to crank the volume back up the second she turned away, then slowly righted the chair and sat down again, thumbing through her Physics III book.

"I can't do this anymore!" Hiro exclaimed, a note of desperation in his voice.

Tadashi glanced over at his little brother, whose face was dominated by the dark bags under his eyes. He couldn't help but think the boy was too young to look this tired and this stressed.

"If I don't get a break soon," Hiro continued, gesturing wildly, "I'm going to go crazy!"

Tadashi genuinely felt bad for the boy. This was his first semester at college after all. It was to be expected. "You get used to it," he tried to encourage his brother. "It's a bit of a…rough adjustment at first, right guys?"

GoGo scoffed. "Try no adjustment. You just gotta woman up and get it over with." She snapped her bubblegum for dramatic effect and returned to her textbook.

"Tadashi's right, Hiro," Honey Lemon glanced up from a biochemistry textbook. "It'll be less stressful after your first few semesters."

"You guys should lighten up," Fred paused the game and joined his friends at the table in the center of the garage. He put an arm around Wasabi and another around GoGo. "Take a break, eat something…"

Wasabi pulled away. "No! I can't take a break! Do you see this?" He held up a study guide as thick as the textbook itself. "I need to know all of this cold by next Tuesday!"

"Just a quick one, please?" Fred asked. "I'm bored and hungry, man!"

Honey Lemon looked up, thought it over a minute. "Guys, maybe we should get something to eat…"

GoGo sighed, deciding to humor Fred. "Fine. I'll go to Radical Ramen, pick something up, and be right back."

"Yes!" Fred whooped. "I'm coming with!"

"No," GoGo insisted. "It'll be faster if I do it myself." She made for the door and Fred followed her out anyway.

Wasabi sighed. "I better make sure she doesn't kill him."

Tadashi chuckled, rising to his feet as the physics major got up from the table and followed the other two out of the garage. "I need a coffee refill," he stretched, grabbing his mug. "Can I get anyone else anything while I'm up?"

"I could use some coffee," Hiro sighed.

"I…don't think that's such a good idea. Besides, you don't even like coffee!"

Hiro yawned. "At this point, I'll do anything to stay awake."

"You're not drinking coffee," Tadashi decided. "Honey Lemon?"

"I have my green tea," she replied brightly. Tadashi nodded with a small smirk of his own and disappeared through the garage door to return to the house.

Honey Lemon was startled by Hiro's head bashing against the desk. "Hiro! What's wrong?"

"Expos," the boy mumbled cryptically into the table without picking his head up.

"You mean the writing course?"

Hiro picked his head up enough to respond affirmatively. "I have to go in, write an essay in two hours on a book I didn't read, and somehow I'm expected to pass this class." Another thud indicated his forehead was firmly planted in the veneer surface once more.

Honey Lemon shook her head ruefully. She didn't remember a thing from expository writing. "At least you're getting the requirement out of the way?" she offered hesitantly, as if trying desperately to find an upside. "Fred's an English major. Maybe he can help you when he gets back."

Tadashi returned with a mug of coffee and a can of soda and a pack of gummy bears, which he chucked at his brother. "I know I'm gonna regret this when you can't sleep later but maybe this'll perk you up."

Hiro tore into the candy with renewed gusto.

Tadashi sat back down. "How's it coming?" he inquired.

"Almost done with organic chem," Honey Lemon declared with relief, indicating a stack of bright pink flashcards she had made. "Then it's on to calc III. You?"

Tadashi flipped a page. "I'm almost done with my biomechanics course. I still have to study for physics. Finals are going to be the death of me."

Hiro was about to say something when he felt the table and chair begin to shake. It was faint at first, then subsided. "What was that?"

Tadashi shrugged, a frown creased across his brow. Honey Lemon looked around. "Maybe there was a truck passing by?" she offered.

Tadashi shook his head. "I don't think a truck would do that…"

Then a second set of shakes hit, stronger than the first. His coffee sloshed out of his mug and a few stacked textbooks fell over on the table. A startling realization hit Tadashi as the shaking got more powerful. Earthquake. The lights began to flicker.

"Tadashi?" Hiro's alarmed voice cried out.

"Earthquake!" he shouted in response. The tremors grew stronger still. Car alarms blared. Glass shattered as things began falling off shelves. "Get down!" Tadashi ordered, rising from his chair and pulling Hiro and Honey Lemon under the table with him as their textbooks tumbled and fell around them. He was desperately trying to remain calm but he couldn't remember the last time the tremors had been this forceful. He could feel the floors and walls vibrating with the movement of the earth, groaning in protest of the unnatural shaking. They weren't supposed to be making noises like that. They were meant to withstand something like this. But still the tremors intensified. Tadashi watched in horror as the far wall of the garage tipped perilously and began falling toward them. Thinking fast, he grabbed Honey Lemon and his little brother, pressing them flat against the floor and throwing himself on top of them. There was a loud crash and the sound of the wooden table splintering above them. Then blackness.

The last major earthquake in San Fransokyo had occurred over twenty years prior, before Tadashi or Hiro had been born. It had devastated the city, previously a major commercial and industrial hub. Reeling from the disaster and with so many lives lost, infrastructure destroyed, and buildings reduced to rubble, the city was forced to rebuild basically from the ground up. Aunt Cass talked about the day it happened. She had been in school and separated from her brother and parents for almost two days while the city worked to clean up the damage enough to allow people to travel safely. Neither brother could really imagine the chaos besides what they saw in history books. Afterwards, San Fransokyo emerged as a leader in green energy and technological advancement, bringing in the brightest minds from around the globe to create a sprawling metropolis of futuristic technology.

That was the San Fransokyo Hiro, Tadashi, and their friends knew and grew up in. They had earthquake drills from time-to-time in school but the buildings had been re-engineered to withstand even the most devastating of earthquakes. Every few years there would be tremors from the nearby fault but nothing serious enough to cause anything more than some trash bins falling over. This earthquake was uncharacteristic even for a city built along a fault line. The meters were registering quakes that were completely off the charts and unlike anything ever recorded. The city was caught entirely off-guard.

Hiro coughed and hacked as the dust settled. Honey Lemon was curled beside him, blinking dust from her eyes. Her pink-framed glasses had fallen off in the quake but she seemed otherwise unharmed save for a few scratches.

"Are you okay?" she managed to wheeze out. Hiro nodded. Tadashi. Where was Tadashi? The fourteen year old twisted around and spotted his brother sprawled out on the ground. The table had collapsed on them and he'd taken the brunt of the impact. Rubble and bits of roofing pinned the debris to his brother, who was bleeding from the side of his head.

"Tadashi!" Hiro frantically clawed at the debris, trying to pull it off his brother. "Tadashi!" Honey Lemon saw the young man's prone form and joined Hiro in trying to dig him out. The boy's mind was racing. He had just gotten his big brother back. There was no way he was going to lose him again. "Tadashi!"

A/N: So I'm ending here because I'm evil and want to toy with your emotions. Poor Hiro. He thought Tadashi was dead only to find him alive only to now maybe lose him because he was protecting him. And what about Fred, GoGo, and Wasabi? And Aunt Cass? And MOCHI! WON'T SOMEONE THINK OF MOCHI! And Baymax of course. Well all will be revealed in due time. I'm going to use this story to launch into a few more BH6 short series but first I'll add a few more chapters to this. Let me know what you think with a review? Pretty please?
