As someone who wanted to be a doctor in the future, there is no way that Arit would not know all about Jeanne! Jeanne was one of the most popular healers in the country, and so Arit has been following all of her actions for some time now. Jeanne wasn't like the other superhumans who just wanted money; Jeanne joined the NSA instead of joining any independent guild because the NSA promised her freedom to act independently whenever she wanted. That has allowed Jeanne to travel to many different parts of the country to help out whenever there was a disaster that was too large to be handled by normal doctors.
Arit really looked up to Jeanne, but she also knew that Jeanne was impossible to fool. Jeanne's power centered around healing, but she also had an alternate minor power called Analysis that allowed her to easily diagnose injuries and diseases with only a touch.
