Deucalion and Hayden in “Unfinished Business”

Deucalion

I know the talons were created by the Dread Doctors.

Hayden

So, what?

Deucalion

So, Theo believes he can fit them onto his own claws like a couple of press-on nails? Use them to siphon the power from the Beast? [He chuckles] Good luck with that.

Hayden

What do you mean?

Deucalion

The Dread Doctors would have designed those talons with a specific frequency. For a specific person. As a genetic chimera yourself, I would have thought you'd understand how often the body rejects an organ, especially one from an outside donor.

Hayden

[horrified] If he puts them on, then...

Deucalion

Yes, Hayden. They'll kill him.
