Quote 10
A brave man's blood is the best thing on this earth when a woman is in trouble. You're a man, and no mistake. (12.28)
We don't want to tell Van Helsing how to do his job, but we can think of a lot of things that are more useful to a "woman in trouble" than "a brave man's blood."
Quote 11
She is one of God's women, fashioned by His own hand to show us men and other women that there is a heaven where we can enter, and that its light can be here on earth. So true, so sweet, so noble, so little an egoist—and that, let me tell you, is much in this age, so sceptical and selfish. (14.52)
Van Helsing really thinks highly of Mina, doesn't he? She represents a feminine ideal: She's intelligent, but also submissive and nurturing.
Quote 12
[Mina] has a man's brain—a brain that a man should have were he much gifted—and a woman's heart. The good God fashioned her for a purpose, believe me, when He made that so good combination. (18.22)
Mina's combination of masculine intellect and feminine sweetness makes her almost saint-like in Van Helsing's eyes.
