The wano arc is a portrayal of 'Destiny and Fate' and that's why it's linked to the moon so heavily. Necko and Inu have won because of the moon and its importance is going to be mentioned further down the road. Calling this 'bad writing' without the context of the later story is just stupid at this point. Nevertheless , oda has given a great conclusion to the Jack and Perospero fight. After these panels, i think its just useless to come here and look at 12 year olds bitching and crying all the time.
