In three early episodes of Star Trek Discovery's first season (Context is for Kings, The Butcher's Knife Care's Not for the Lamb's Cry, and What's Past is Prologue), viewers are briefly introduced to Lorca's right hand woman, Commander Landry, being Chief of Security of the USS Discovery vessel.

But given the ruthless nature of the character and given the revelation of about

Season 1 Lorca being form the Mirror Universe

I was wondering if it's possible for this version of the character to derive from the same place?

Has there been any confirmation given on which universe this version of Commander Landry was from?
