Perfectly understandable! Nick certainly wouldn't fault anyone for their bitterness, but rather he would think poorly of anyone who might let it control them. He's not very sympathetic, obviously. Lol
Right now, Nick is more curious to see what Westin plans to do and is keeping as many tabs on them as a whole as he can. He's not concerned about any one person, but more the pack in its entirety. One person is easy to take care of, but several? Not so much, especially if they're unorganized and unpredictable and running solely off emotion.
