Who Are The New Cast Members In Grey'S Anatomy Season 20 On Disney+?

Yara Ellis is a medical student, hiding in a human university while she studies to become a doctor. Unlike most, Yara is majoring in human medicine, veterinary medicine, and minoring in zoology. Since the packs are constantly at war, there are never enough doctors to help injured pack members. She’s been on her own for several years now, escaping from her previous pack and making her own way in the world, hoping to one day return to her roots and become the premier doctor of the packs. Warren Hill is an Alpha, caught up in the constant wars that abound between the packs and the battles that are never-ending. He’s a strong and powerful Alpha, but because of the constant fighting between the packs, he’s never been able to find his mate. One day when Yara is letting her wolf run, she comes across Alpha Warren, caught in a bear trap. She’s heard of this, packs leaving traps so that other pack’s members will get caught and either die a slow death or are easily killed. Warren is in his wolf form, unable to shift without ripping his leg off. Yara carefully springs the trap, releasing him from his metal capture. However, Warren recognizes her as his mate and when his pack arrives, he’s unwilling to leave her behind. Yara doesn’t want to return to Warren’s pack but is unable to fight against the Alpha and his warriors. When she hears that the one who desperately wants her, the one she ran to get away from, is now Alpha of his pack, she realizes that the safest place for her may be with Alpha Warren, even if he is her mate and even if he is unwilling to ever let her go.

But then I discovered a shocking truth—the fated mate the new Alpha had been searching for, the one he marked that night, his future Luna, was actually me?!

Yet the weight of the decision—to carry a child for strangers under such pressured circumstances—leaves her reeling.
