Ti'Ana
Vulcan/El-Aurian Hybrid, She/They
Lt. Commander Ti'Ana is the Command Duty Officer for the night shift on the USS Sally Ride, which basically means she gets to be acting captain and executive officer while the captain and executive officer are asleep.
Ezmi Idaris
Bajoran/Trill Hybrid, She/Her
Lt. Commander Ezmi Idaris is the Engineering Duty Officer for the night shift. Since about half of the night shift is maintenance crews, this is kind of a big deal.
