It makes no sense. How are they going to tie Adira back into the plot? Surely she would have lost them after they got stranded.
Why bring the magical leaf people in at all? It's a silly departure from the more "low fantasy" vibe the rest of the series and the movie gave off. Same thing with the fish people coast guard and to a lesser extent Seraphina. Tbh this was even before the island thing- the forest of no return was silly too and honestly the only saving grace of freebird was that Raps and Cass were cute in bird form.
I admit I might be a bit blinded in my venting but so far it seems like the entire second season has just been filler, except for keeper of the spire
