Meaning that it could be Momma Mi is in fact a duskwight, but due to the stigma around them, she chooses to tell people she is wildwood instead, so she is recorded as being a wildwood in things like the lore book. Which in and of itself gives us a good idea on just how the duskwights are perceived. If you have some of them denying their heritage and "passing" for wildwood, that means things are worse than we think, which mirrors the real world if you look up the history of "passing" before, during and after the civil rights movement in the US.
