I think Ms. Morrell is part of the Alpha Pack.
I went back to the last scenes of the last episode to see if I could make out any faces of the Alphas.
No, I couldn’t get faces. I’m sure Jeff had the editors black them out and turn them into silhouettes. However, Jeff did nothing with the outline and figures of the Alphas.
While watching I noticed one Alpha looked slightly similar to Ms.Morrell.
After the Alphas cornered Erica & Boyd, the next scene shifted to Deaton analyzing black goop when Ms. Morrell walks up.
Very strangely, she is wearing a leather jacket, skinny jeans and boots. Just like the female Alpha in the forest was wearing.
What really got me was how Ms.Morrell’s hair style looked identical to the Alpha’s in the forest.
So I just explained some screen grabs and posted them for you to think about. Sorry for the bad quality photos.
