A/N: So, my first story! It's still a bit of a work in progress, obviously. I'm planning on making it multiple chapters because it'll be kind of difficult to make all of my thoughts fit into one. I know this is a bit short, but I can't guarantee that any of them will be very long. I hope you enjoy it, though! It's gonna become Eren x Levi down the road somewhere. Just be patient.
"Are you sure this is going to work, Hanji?" Eren asked as he rolled up his pajama sleeves. Hanji had woken him up at three in the morning because she had come up with an ingenious drug that she hypothesized would turn Eren into a titan at the point of contact. The drug was a clear, almost thick liquid that nobody in their right mind would put into anybody else's body.
But Hanji was never in her right mind.
"Of course it'll work, darling," Hanji said sweetly as she led Eren outside to the HQ's well, "Have I ever been wrong?" Eren tried to think of a time that she had been wrong, but after coming to no conclusions he just shook his head.
"I guess not." Eren said. He stared at the deadly-looking syringe in Hanji's hand, memories of his dad flooding into his head. The boy began to feel sick to his stomach. "Do you even know if this is going to work? I mean, did you test it on anything else before me?"
"Nope," Hanji sanitized the soft spot of Eren's arm and said feverishly, "So I guess it's just a do-or-die situation, right, Eren?"
Eren didn't have time to protest when Hanji stuck him with the syringe. She pushed down on the small pump, and the liquid formed a painful lump the size of a penny under Eren's skin. Against Hanji's hypothesis, the drug didn't turn him into a titan at the point of contact. The boy stared at the painful lump on his arm while Hanji watched him for any changes, although Eren didn't feel any urge to change at all. A very, very small stream of smoke trailed from where the needle had poked him. His titan powers were quickly healing the small penetration.
Hanji looked up at the white moon and made a muffled sound of concentration as she pulled out a small note book out of her jacket and wrote something seemingly important in it. She smiled and put it away before looking back at her test subject. "So, how do you feel?" She asked.
"How do I feel?" Eren began to feel panicky. He grabbed his upper arm just above the lump and thrust himself to Hanji. "How am I supposed to feel, Hanji? You injected some mysterious, possibly deadly liquid-thing into my arm! What if I die?"
"Oh, calm down Mr. Feisty-Pants. You're fine." Hanji smiled and at Eren and patted his shoulders. Eren looked down at the lump on his arm that showed no sign of going away any time soon. Hanji watched him.
"Don't touch it," she said, "Touching it may reverse whatever it's doing to you."
"But what if it's doing something bad, Hanji?"
"Jesus, Levi was right," the mad scientist laughed and shook her head, "You really are whiny, Mr. Feisty-Pants. Go back to bed, Eren. I'm sure that the lump will be gone by the time you wake up!" And with that, Hanji walked back to HQ and left Eren outside, standing in the blue-gray moonlight next to the well of the previously failed titan experiment.
