Hernandez's last assignment prior to taking command of Columbia was on the Republic, under Captain Jennings. When she left the ship, Jennings told her that she could have anything that she wanted. Hernandez ultimately chose to take his chef. (ENT: "Affliction")
Hernandez was promoted to captain in 2154. She was then assigned, along with several other officers, to audit Archer's debriefing subsequent to Enterprise NX-01's return from the Delphic Expanse. After Archer was ordered to take some time off by Admiral Forrest, Hernandez joined Archer as he went rock climbing.
