She is not afraid to dig for the truth and expose it; politics and social issues rank high in her interests. Isabel treats her nephews like young adults and expects the best from them.
It takes her a while to accept that the quest and the Seven Stones of Power exist, but once she does, she is supportive of the boys' role in finding the remaining stones.
Isabel is also instrumental in keeping the boys' cover story intact each time they go on another leg of the quest. Secretly, Adam and Justin hope she never has her own kids because they
consider themselves the sons she never had. Adam is especially close to his aunt.
"We're not looking for trouble, lost archaeologists, or hidden treasure. We're going on a nice, safe tour with nice, safe people and that's all. Adventures only happen in books."
