Loud crashing accompanied by Hange's frantic screams and giggles echoed down the dark hallways. If one didn't know the science loving freak they might assume some other not-to-be-named activity was going on, but was going on was just what science made her do. Sometimes, an emergency experiment popped up that just couldn't wait. Hange was a bit of an insomniac, and so these experiments usually happened to be around midnight, occasionally three in the morning.

This late night experiment, however, was different from the rest. It happened to be hazardous enough that if even the slightest thing were to go wrong, the entire headquarters could be filled with toxic, flammable gas (otherwise known as Arsine). Now, Hange didn't seem to think this was such a big deal, as she ran the experiment without even thinking twice. But, Inevitably, something was going to wrong.

"Uh oh," Hange pulled down the gas mask that had been resting on her head. "Better luck next time, I guess." She shrugged and took her time leaving the room, the disappointment of the experiment having failed taking away from her usually hyper attitude.

"I suppose I'll have to evacuate headquarters now," she mumbled boredly. "What a bother..."

The chilly evening air flowed through the hallways as the Survey Corps began to evacuate. They would have to do it quickly as well, Hange happened to be the only one with a gas mask. Eren hoped everyone was okay. He squeezed the hand of his lover as both of them (without pants on, thankfully they had boxers) ran through the hallways toward the entrance, and finally, the front yard.

All of the Survey Corps was there, even Sasha, who had stopped in the kitchen to grab food.

"Eren!" Mikasa ran toward the two of them, followed by Armin, Connie and Sasha.

"Wait a minute..." Connie looked confused. Why was Eren shirtless, and why was Corporal Levi wearing his shirt?

"Oh shit!" Connie looked away. Armin was blushing, and Mikasa looked like she was going to kill the corporal. Sasha was indifferent.

"What?" Eren wondered why everyone (excluding Sasha) was staring. Suddenly, he noticed he was shirtless and Levi had his shirt on, not to mention they were both in their boxers. "Oh..." Eren started blushing with the rest of them.

"Does anyone have a problem?" Levi spoke calmly, an eyebrow raised. There was silence.

The loud footsteps of the commander sounded behind them. Erwin Smith was smiling as he put a hand on Eren's shoulder.

"Well well, what do we have here?" Erwin could barely contain himself. For the first time, Levi joined the blushing.

"Ya know Levi, if you're having a rough night I'll allow a few days off," By now, Connie was smirking too.

"Shut up Erwin," Levi's voice was menacing, deadly.

"I'll make sure there's Advil in your supplies,"

"Erwin-"

The commander laughed.

"I'm just kidding, Levi," He smiled and winked.

"Noooooo," Levi buried his face in Eren's chest.

Eren smiled and played with his hair.

"Mikasa!" Armin yelled, restraining the soldier.

This was going to be a long night.

"Why was everybody making fun of Levi and Erwin," Sasha asked Connie innocently as they made their way to training.

"Because..." Connie blushed.

"IT'S BECAUSE CAPTAIN WAS GETTING THE D!" He hadn't meant to be so loud about it, but the subject made him uncomfortable and thinking Eren and Levi...

Sasha looked clueless.

"They were having sex, Sasha!"

She had no idea what they were talking about.

"What's that?"

Connie had an idea.

"Why don't you ask Commander Erwin?"
