I'm so ashamed of not realizing that up until now! 

Gen 9 will introduce the first region with TWO primary professors. Of course, there were regions with more professors (Unova had Aurea, Cedric and Fennel; Alola had Kukui, Burnet and Samson; and Galar had Magnolia, Sonia and Hop {to some degree}). But only 1 of them was the main one, while the new one will have two. 

We don't know if they will be version-exclusive or be in the same game but one of them is going to be our mentor and the other not, but we know that their names are Sada and Turo. 

And only now have I realized that their names come from Spanish words "pasada" and "futuro", which mean "past" and "future" respectively, with the first one being used in "feminine" form and the other in "masculine", since in Spanish nouns (and adjectives) have two forms, if they can refer to either masculine or feminine objects. And that matches well since Sada is a beautiful, wild female, and Turo is a hot, chad man. 

Still... I feel stupid for not realizing that despite being learnt Spanish for 6 whole years!
