I was doing some digging and I stumbled across the Bigender identity, wher an individual shifts between one gender identify to another. In Alex's case the child of Loki shifts from male to female. Where as genderfluid can identify as a non binary gender as well as male and female. But Alex has only been shown to be male and female. I know Rick Riordan probably did this to introduce individuals to shifting gender identities but since it is only between male/female gender identities I’m wondering if Alex is actually bigender. I know it is different for each individual but this just got me thinking. What do you think?
