The secret is a simple one.
Even though one of my peeps worded my speculation last week on why Shione made a 180 better than I did it was simply because if the ultimate wish the group made seven years ago was granted Noel would disappear. Just as I suspected.
The majority of the episode was dedicated to the gang setting up the planetarium, hoping Shione would come and Shione getting ready to move back with her father because there are still a couple of episodes left before the series finale and the writers started relying on the old “Teenagers are angsty and do not like to discuss their feelings” padding material.
“I can’t properly explain my actions because teenagers love bottling up their true feelings and there are still 2-4 episodes left on the show before it ends. Instead I’m going to waste everyone’s time dragging this nonsense along for as long as time permits it. Also calling the saucer here seven years ago was MY idea, not Nonoka’s.”
Oh and Noel fainted because she went to the see the planetarium anyway and her being far away from the saucer too long was not a good idea.
Reviewing this anime when it ends will be very easy. I just have to copy/paste my AnoHana review and make some tweaks here and there. The shows are nearly identical.
