As Izuku begins his internship with the Langstroms, he's tasked to learn how to grab one of the bats with Dr. March. Dr. March teaches him how to care for the bats and how to properly move them from their cages.
"Alright, kid when you're grabbing one of the Bats remember to be calm & quite the smallest movement can set them off." Dr. March spoke irritably, wanting to spend as little time teaching Izuku so he could get back to his work.
"Yes, Dr. March," Izuku said anxiously, not wanting to annoy Dr. March. Izuku followed Dr. March into the room containing the bats holding a cage in his hand, Dr. March instructed Izuku to Bentley grab the bat and put it in the cage. Izuku's palms started sweating profusely as he carefully grabbed the bat and put the sleeping Bat in the cage making sure not to startle the animal. Dr. March waited impatiently with a scowl on his face wanting to get it over with so he could go back to his research.
"Good job kid now if you're done take the bat to Kirk he'll examine the specimen and he'll give you more work to do." Dr. March said irritably, "And don't forget to lock up the room before you leave." Dr March threw Izuku the keys to the room. Izuku failed to catch the keys in time causing them to fall on the floor causing Izuku to pick up the keys off the floor.
As weeks pass Izuku starts to get a hold of the job and impress Kirk & Francine with how fast he is completing the jobs with impeccable speed, skill, intelligence, & ingenuity. But one day while Izuku was grabbing some paperwork from downstairs for Kirk he was stopped by his former childhood friend Katsuki Bakugo.
"WHAT ARE YOU DOING HERE NERD?" Bakugo yelled, "I-I-I'm doing an internship here Kacchan that's all." Izuku said scared for his life. Bakugo eyed the paper he was holding and snatched them from Izuku's arms "What's this Deku? Some important documents." Bakugo said as a twisted smile spread across his face "Hey give it back Kacchan they're really important." Izuku cried out In anguish Bakugo simply responded "Oh really, then it would be a shame if something bad happened to them…" & with those words, Bakugo Put the papers between both palms of his hands & activated his quirk destroying the papers in a small explosion.
Izuku looks in shock as he sees the papers burnt to a crisp almost illegible, Izuku tries to stand up to Bakugo saying "What have you done, Kacchan?" only to be pushed down as Bakugo taunts him saying "You're pathetic, Deku. Always trying to play hero." He spat, Bakugo decided to walk away leaving Izuku covered in cuts & bruises
As Izuku lies on the ground crying, Kirk comes down the stairs to see the commotion that is going on. He sees Izuku covered in cuts & bruises crying on the floor, "IZUKU!" Kirk yelled out "Izuku what happened to you?" Kirk said worry filling his voice as he looked at Izuku. Izuku sniffled as tears ran down his face like waterfalls, unable to talk about what happened, Kirk took him to his office to clean some of the cuts.
As Kirk cleans Izuku up he asks Izuku "What happened Izuku, did someone hurt you?" Kirk asked, trying to comfort Izuku. Izuku didn't want to speak and just sat in front of Kirk sniffling still "(Sighs) We'll Izuku I'm going to have to inform your mother about this I'll let you take some time off. You need to collect yourself & when you do tell me what happened here today, only then will I let you back in the lab." Kirk said reluctantly he didn't want to let Izuku go home but it was clear he needed some rest after whatever happened today.
While Kirk is on the phone ringing up Izuku's mother Dr. March walks in carrying a beaker full of a purple liquid as Dr. March walks through the lab Dr. March stumbles & breaks the beaker. Izuku goes over to help clean up, grabbing a dust pan & brush. As Izuku cleans up the broken glass he doesn't notice a small cut from the glass not feeling the initial cut, unbeknownst to anybody a small amount of the liquid enters Izuku's bloodstream. When Kirk hangs up the phone to Izuku's mother he takes over the cleaning saying "Izuku it's time to pack your things your mother will be here to pick you up in 15 minutes." Izuku solemnly nods and begins to pack his things all the while Dr March's liquid is slowly taking its effect on Izuku.
