>>58817267Z-A establishes a pattern of multiple important characters having a reliable assistant who helps rein them in, and who specialises in a type immune to theirs
Canari uses Electric types, and her gramps is a Ground specialist
Ivor uses Fighting types, and his sister uses Ghost
Corbeau uses Poison types, and his lieutenant uses Steel
It's also implied for Vinnie, who uses Dark and Normal types (both of which have a type immunity)
Then you get to Jacinthe, a Fairy user, and the lieutenant who's supposed to keep her under control uses... Dragons. This is what we call a red flag.
