Isabella has a friendly crush, on her neighbor, for all we know she married neither brother. How is that possible, one of three ways:

1. Amanda's father has a brother who married Isabella 2. Candace marries the unseen never mentioned older brother of Isabella's 3. A close friendship with Candace developed over the years culminating in Candace's children referring to Isabella as an aunt despite no familial attachment.

I prefer option 3 myself because such situations are rather common in a modern age. Plus so few people would expect it
