Did he learn that he is an omega orr when will he

Eventually..

I think he's supposed figure it out at the end of the season cause I'm pretty sure someone said that Etienne has a surprise heat while in the garden with Rishar

I just checked he's gonna find out in 2 chapters

The last chapter for the season he funds out

Thank youu

Is the next season out already

I don't think so, at least it's not uploaded yet on the illegal websites.
