This.. is pretty scary.
Sarah, Uber-Were that she is, still is heavily biased towards her human side.. and humans tend to really really like deferring to authority if they can, whether that authority is officially sanctioned or in the form of one simply having more knowledge and experience.
Gus is a police officer, And an older and more-experienced were. And, well, as much as becoming a were has inconvenienced her she has been even more of a pain back to Peter and everyone else with her lack of control over herself. Perhaps, maybe, for Peter's sake, she should take the nice gentleman's offer so she can be less of a load to her boyfriend and the rest of the people who are bending-over backwards really to protect her. After all, he's in Law Enforcement, and could not possibly have any wicked ulterior motive...
This.. can only end in tears.
