At the end of Warbound, Faye reads Francis's mind to discover what the Nix's power looks like. While she's in there, she stumbles upon how he really feels about her. She's so touched that she's nearly reduced to tears.

For the climax of Warbound, Faye needs to use several different powers at once. She achieves this by thinking of all her friends and allies, and trying to imitate them.
