19. How did Wolf know so much about Chelsea's third wolf?
Wolf was told by Wyatt... when Wolf tries to talk to Chelsea/Gabriel he tells them in unconditional.

20. Did we ever find out who was watching Chris and his family for all
those years and had Seth take Rainy and why?

Seth was watching Chris... he saw when Wolf's mate left the children in Chris' pack. He continued watching until finally realizing that to get back at Chris, he'd hurt Rainy.

21. Whoever was behind taking Rainy they took Chris's sample, but Anna
had one too. Could she have been working with them more than we
realized? Maybe she was the one who helped steal the samples.

Anna was working with no one but her crazy self...

22. Why are the memories of JAX always just black faceless shapes? This is a tricky one to answer... so I'll give you guys the answer I had when I was creating this JAX person.

First, I had to think of the gifts the Chosen one would have... she can read minds, so that means if I want he or she to be anonymous, I had to counteract what she could do. Meaning...

A. JAX can either spell people to not remember(deducing that he's Fae or knows one)

B. Was once maybe tampered with and the testing, like with Kaden and Kieran, changed their abilities.

C. Has the ability from the get go to be seen that way making he or she their own supernatural scrambler

D. Has someone around he/she with that ability – a supernatural scrambler

I've toyed with idea that JAX is like Wyatt (Jade's father – Etta's mother). Why? Well this story line is going to be toyed with in Loving Ashlynn.

JAX is a mystery, but super important.
