they come from old money, so they're very well off, they have an older half sister from their father's first marriage and there are a few niblings in the comm that are her children. ethan was the oldest son and a lot of pressure was put on him and he basically noped out of the family as soon as he got his inheritance. the younger brother got away with a lot more so they didn't really get along as kids, but as adults they have a somewhat better relationship even if ethan is still slightly jealous of him being able to take whatever path he wanted in life just because of his birth order.
