After Katie's duel against Sandra, the white-haired Luna joined her mate in training the werewolves, leaving the hunters to the Mighty Warriors, Elders… and oddly enough, Sandra.
This happened partly due to Aunt Marie's insistence. It was now known that humans simply weren't built to handle training from a werewolf who didn't fathom the concept of pain and limits.
That didn't make the alternative any better though. Having heard this fact, the werewolves were stiff around her, at first.
After interacting with her though, they found that she was easy to talk to and insanely tolerant. They quickly got used to her as she made them go through drills much more dire than what Alpha Phillip had been putting them through.
Well, it was either they suffered through the drills or tried to salvage the situation. Katie turned out to be prone to jokes and easily warmed up to any banter they offered her.
