They do deserve it tho, assholes that they are, not only in the dialogue but if you don't have a fire type fern's Ferroseed/Ferrothorn will absolutely wreck you with curse,gyro ball and power whip/pin missle. and i will never forgive him for the 2 times he sweeped out my main 6 pokemon in the nuzlockes i did!, Also the boss fight agains Fern and Blake is really freaking hard, since Florinia has only grass types (and 1 ground type) so Blake destroyes her and you are left to fight both of them on your own.
