Hedda is afraid of more than one scandal here – not just the obvious downfall of her role in Eilert's death, but also the general social transgression of getting too involved with a man of questionable repute. ("Questionable repute" is Victorian for "raging alcoholic.")
| Quote #5
Hedda imagines Eilert living life to the fullest, which in her mind means disregarding (or being "fearless" of) the rules of society.
| Quote #6
Here we see the rules of society being used as front for ulterior motives. Brack doesn’t really care about the Tesmans’ reputation; he just wants to be the only other man in Hedda’s life.
