How old is Falck

not that it makes any real difference. I’m just confused and it gives me the uncanny valley effect sometimes because her hair says she’s like an 80 year old but when you look at her in the face she looks like a 40 to 50 year old when I look at her, I get the impression I’m looking at a skinwalker that’s confused of what it needs to look like in a combat zone. So how old is she?
