There was an extreme accident which you had a condition that caused you to have bleeding badly. A man had his hands on your Judgular vein, which stopped your breathing but nobody was aware because he was trying to stop your bleeding. But you weren't an adult. You were a kid. The league of villains were around and saw, then Dabi stepped up.

"Your killing them."

The Man who was trying to stop the bleeding spoke up since he didn't like Dabi because of course. He was a Villain.

"I'm saving they're life, They were bleeding out."

Dabi rolled his eyes, then Glared at the man not Appreciating the way the man spoke to him.

"You have it in the wrong place."

He said sternly, then the man spoke up in annoyance, not liking a villain telling him what to do.

"I think I remember enough of Anatomy 101."
