Pina: "...because carnivores are weighed down by their instincys and desires, they can't be beautiful." Bill, Aoba, Kai, Tao, Juno, Sheila: "And we took that personally." Riz: *confused staring*
Despite Bill and Legoshi's backlashes in the past, you can see they still care for each other and can put their differences to rest. I like that about their friendship.
In the stage rage episode, Legoshi got instinctually triggered by the whole blood thing so he got super mad and as such his judgement was clouded but in the end they're friends. They have their ups and downs but at the end of the day, both of them will help each other.
Legoshi has growled before, right before him and Gouhin intercept the Shishigumi hide out in season 1 episode 10 or what about when he's about to kill haru and he's repeatedly saying "I'll eat you"
