However, “Carlin almost decided to abandon the journey and liquidate Half-Safe, but was convinced by his wife to continue.”
Sounds like she was – at least for a time – just as invested.
Well, she did accompany him for the first five years. She just kept getting seasick. Too bad they ended up divorcing but that's the power of obsession right there.

I came to the bit about his journey taking ten years and thought "his poor wife".
I later saw that they divorced.
