I am wondering why the 5 pillars were not there.
They were the ones that planted the seed.
It would have been nice to get reactions from them.
Also now that the tree is still going. What about the tree with its original role protecting the forest from overtaking the land?
I think the writers are running out of ideas and this is a stretch.
This will be the end of the current FIM season and I guess they didn't want to leave the Magical crystal tree dead.
