Daniels (aka Dani) was a crewmember aboard the colonization spacecraft USCSS Covenant. She was the wife of Captain Branson. She was serving on the Covenant during its disastrous voyage to Origae-6, during which it suffered several catastrophes that resulted in the loss of most of the ship's crew and its hijacking by David.
Daniels was part of the expedition team that set down on Planet 4. She was one of two Covenant crewmembers to survive the incident, alongside the ship's pilot Tennessee. However, they were captured by David when he hijacked the Covenant, presumably to be used in his future experimentation.
