Some chit-chat going on that Diana and Adalind are not who Black Claw really want, they want Baby Kelly, because he could turn out to be a Grimm and Black Claw want Grimms to join then.
How would a Grimm be helpful to Black Claw/? What's their power?
1.) Grimm abilities may or may not be past on from one generation to the next.
2.) They can see Weson
3.) They're good fighters.
4.) They've killed Weson for centuries.
5.) They had a really cool trailer filled with Grimm artifacts (but that's gone now).
What's so great about being a Grimm?
