I don't remember, but I think that a hatzeg ate the baby zalmoxes in ep. 5

There's a zalmoxes laying dead between the 2 hatzegs

And there's a zalmoxes alone on a nest-like thing on the water

Maybe the Zalmoxes in season 3 will get the good ending. Maybe its raft drifts away to a new island where it can live... and then get eaten by something else

Zalmoxes are like dogs in sad movies.
