So I was thinking:
So Tau has a daughter
And that Daughter's appearance is used as Edda's Avatar.
Some of those Eddas turned blue.
One of them then built a teenager (young adult?) human body, seemingly with all the normal organs and functions since she could bleed, drown, needed to drink and could get stomach cramps when she was in panic.
So, this was a full or mostly biological body.
But this body was made using the Daughter's data, right?
So this means her DNA has to be mostly the same as the Daughter's excepting the stuff like eye and hair color.
Wouldn't this make the current Sapphire biologically Tau's daughter?
