Chiyo: Izuku dear I've made an arrangement so you can see All Might tomorrow at Takoba Municipal Beach Park.
Izuku: Really granny Chiyo?! Thank you so much! I can ask him if I can be a hero! Um why am I meeting him at Takoba Municipal Beach Park? Isn't that place a literal dump?
Chiyo: It is so no one will be there. All Might wanted to meet someplace discreet. That way he wouldn't have to go through a hoard of fans to speak with you.
Izuku: I think I understand granny Chiyo. I can't wait to meet him!
Inko: Thanks for setting this up mom. It really means a lot to us.
Chiyo: Don't mention it Inko dear. I just wish Izuku would take our word that he can be a hero.
Izuku: I believe you and mom, but you two love me so much. I just want to hear it from someone else. Katsuki and everyone else are always saying I could never be a hero.
Chiyo: I understand dearie. Well you should head to bed. You have to be up early to meet All Might.
Izuku: Okay granny goodnight!
Chiyo: Goodnight dearie.
Inko: Goodnight Izuku.
Inko: Do you think All Might will tell Izuku what he needs to hear? I can't help but worry he'll hurt Izuku.
Chiyo: That oaf better know what to say. If he hurts my precious little grandson he'll have hell to pay.
The next day at Takoba Municipal Beach Park.
Izuku: I'm here but where's All Might? Maybe a villain attacked and he's running late. I'll wait for him.
Several hours later.
All Might: I AM HERE! SORRY I'M LATE YOUNG MIDORIYA! I GOT CAUGHT UP IN SEVERAL VILLAIN ATTACKS. SO RECOVERY GIRL TELLS ME YOU HAVE A QUESTION TO ASK ME. WHAT IS IT YOU WANT TO KNOW?
Izuku: Wow All Might you really came! I I want to know if I can be a hero.
All Might: WHAT'S YOUR QUIRK YOUNG MIDORIYA?
Izuku: It's called nervous system check. I can see the nervous system of any living thing. See.
Izuku's eyes begin to glow.
Izuku: A-all Might your chest. You're hurt really badly.
All Might: ?! YES I WAS INJURED IN A VILLAIN ATTACK A FEW YEARS AGO. PLEASE KEEP THIS A SECRET AND DON'T TELL ANYONE. HONESTLY YOUNG MIDORIYA I THINK YOUR QUIRK MAKES YOU A GOOD FIT FOR THE MEDICAL FIELD. I DON'T SEE YOU BECOMING A HERO WHO COULD SAVE THE DAY. I'M SORRY BUT I NEED TO GO NOW. GOODBYE YOUNG MIDORIYA.
All Might jumps away. Izuku begins to cry.
Izuku: S-so I can't be a hero?
Izuku heads home.
Inko: Izuku?! What happened?!
Izuku: I-I can't be a he-hero.
Inko: Oh my baby yes you can be a hero!
Chiyo: I should have known that oaf would louse this up. What did he say to you Izuku?
Izuku: He said with my quirk I-I should go into the medical field. He didn't think I could be a hero who could save the d-day.
Chiyo: That idiot! Izuku dearie listen to your grandma my quirk only heals people and I'm a hero. And Rag Doll from the wild pussy cat's quirk just tells her how strong someone is and where they are. Mandalay is just a telepathic. They're basically quirkless when it comes to actually doing hero work. You can be a hero.
