Because they could get away with not signing Rose on as a main cast member, same situation for Addy and (at first) Mekia, they all appeared in the same amount of episodes, Rose was (and is) relatively unknown, Addy is really only known for Reign, Mekia's about as unknown as Rose but she was upped to keep her off Chicago Med (IIRC for that one). The other regulars all appeared in a minimum 19 episodes, and those were all-show main characters Lana Parilla and Robert Caryle.
