Avina is going to struggle with sharing her alpha title. Being alpha has been her protection  against men and sharing that will feel like giving up her protection. Devin is gonna have to show her that he is not like the men of her first pack.

I think she is also going to struggle with the balance between hunting as a pack and also being greedy with her food.

And like Devin, she is used to dealing with change on her own so it will be a while before she allows him to help.
