NCIS: Los Angeles Season 1Edit
Hetty first appeared in the NCIS: Los Angeles Season 1 premiere episode, "Identity" where she was revealed to be the new Operations Manager, having presumably replaced Lara Macy in the aftermath of the move that had been triggered due to the attack on NCIS Special Agent G. Callen.
She was first seen talking to NCIS Special Agent Sam Hanna over some money he owed her which was revealed to be 61 dollars and a nickel.
After Sam paid her back, Hetty greeted Callen who she was surprised to see back at work a month early.
