Attempted Murder

Both Luna and Headmaster Blake were flabbergasted at Number One's words while the old Alchemist almost exploded. 

"Who is this kid?! How dare you offend me like this?!" the old Alchemist cried out in anger while turning to Headmaster Blake for help. "Get this bastard out of here before I lose my temper!" 

"You should definitely lose much more than that. How about losing your life for being such a shitty Alchemist?" Number One added fuel to the fire with more insults. "Honestly, where did you study Alchemy? We need to find your master and kill him too for teaching such garbage to you." 

"Number One! That's enough!" Headmaster Blake finally stepped in with his voice raised. "You better explain yourself! This man is a well-respected Alchemist. He came to help Luna with her injured arm."

"Help? With this garbage?" Number One questioned while rolling his eyes which made the old man flip.
