Teen Wolf, Season 5

[Scott and Deaton are examining Belasko's talons]

Scott:
Find anything?

Dr. Deaton:
Maybe. Are you sure this guy was a werewolf? As far as I can tell, these claws are actually talons. In fact, they're the talons of a harpy eagle, one of the largest known birds of prey.

Scott:
[confused] How does a werewolf get talons?

Dr. Deaton:
Personally, I'm more interested in how these talons somehow were able to absorb your powers. The only one who should be able to do that is a Beta of your own making.

Scott:
Someone like Liam?

Dr. Deaton:
Exactly.

Scott:
And what if I let someone into my pack? Like another Beta?

Dr. Deaton:
I would normally say no... But, I'm starting to wonder if the rules to our supernatural world aren't as rigid as I once thought. Or maybe someone's trying to change those rules.
