Transforming someone and evolution has always been a problem for the Silverstar Pack.
Mainly, there were uncertainties involved.
Not to mention, the Werewolves within the Silverstar Pack always had a unique bloodline due to the System being a part of their transformation. It was always new bloodlines that Rex and the others needed to learn and adapt.
Preparations are preferable, but they couldn't prepare for something like this.
It was random, the path of evolution can't be predicted.
Just like now, there was no way of knowing Evelyn turning into a Purple Regalia Werewolf.
Upon Adhara claiming to be the host, Evelyn's state calmed down.
She was not moaning in pain anymore—but even then, she passed out when the Luna mark was deactivated. Rex checked on her vitals, and he found that there were no abnormalities, and that alone was a relief.
But now, their attention turned to Adhara who had no clue of what had happened.
