It's still unknown what Pete is. Josh is a normal omega from a mainly beta family.
And Chase had blue eyes before he manifested as a dominant alpha, so that is also possible for Pete. Actually it is normal for dominant alphas to have a different eyecolor before they manifest, only the born manifested which are very rare, have purple eyes from the start.

Sooo I just noticed that Pete has a green eyes and according to the story and other stories that is connected to this, if a person has purple pupils then they are those hyper dominant alpha. Is Pete an alpha?
