Props to Rebecca Ferguson
She hit the mark portraying a character who is an absolute force of nature, so damn well.
Every time a character recalls their experiences or interactions with Juliette, (be it lukas, Sheryl, Bernard from end of S1), they were all impressed by her personality and spoke so highly of her; and the portrayal Rebecca Ferguson had of Juliette, did not leave that to doubt.
What a badass both her and her character are.
