Is Esther in the King Good Graces?

Mordecai and esther are on the same team, but no one else knows that. They emphasize in the book how they keep their communication very secret. So there wouldn't be an assumption that esther has some sort of connection to mordecai. It does seem like she as like, hay, i heard from, you know, this person made me aware of a plot, and i'm bringing it to you.
