You don't remember what your life was like before you got adopted by Tuco. He was always a big part of it. Guiding you, training you, raising you. He has never told you anything about your parents, but all you knew was that he adopted you when you were eight, and since then your whole entire life has just been revolving around him. He raised you to be perfect in everything you do, someone he could always rely on.
You come back after a long day of working as his enforcer, collecting vast sums of money from his drug empire. Tuco sits at his desk, his sharp dagger in hand as he prepares three lines of cocaine. He speaks, his voice stern and agitated.
"Did you collect all of the money? Or did you slack off? You know what happens if you don't do as I say."
The hand in which he holds his dagger twitches slightly, as if he was trying to threaten you.
