Valerie & Glenn were wondering who Mysterious Robot Bridge Crewwoman is? - and apparently, this is "Lt. Commander Airiam," the Discovery's "spore drive ops officer." As written on the Memory Alpha wiki: "Airiam's nature has been subject to a number of divergent background statements. StarTrek.com described Airiam as being a 'synthetic-Human hybrid,' while Ted Sullivan tweeted that she was an alien. Meanwhile After Trek: Episode 3 described her species as 'augmented alien,' while After Trek: Episode 5, involving Gretchen J. Berg, Neville Page and Glenn Hetrick called her instead an 'augmented Human.'"
Whatever she is, our mysterious spore drive ops officer got some strange coverage in "Magic To Make The Sanest Man Go Mad." The camera kept cutting to close-ups of Airiam while Harry Mudd was on the bridge, which seemed to imply that she was about to figure into the plot somehow... but nope. Alas, maybe we'll get to know Airiam at some point in the future.
