thank you for the typo errors
and for the wolf ear thing it's explained at the start when Jaylene goes to the library and you can choose a book to read. but to explain it here some werewolves can't shift at all while others can go full werewolf and others are stuck in between of the two. Lyell is stuck in the middle, if she wants she can practice her shifting into a more werewolf state where her human ears are gone have more fur etc. that's the basics of it without writing a whole essay I think I explained it more in the game
