Confrontations, First Four Chapters

Couple of things that I wondered…

What if Hazel meets a good friend who’s got really low self esteem, and she tries to push him or her to be more assertive… and then it blows up into a squabble?

Hazel hasn’t been corrupted by this power like in Mistress of the House, has she? If she has, what would be the result if she met someone who had muscle/power/something she wanted… but her victim was perfectly cordial, friendly, mellow, and a true believer in "blessed are the peacemakers"?
