What if Grave Of Maria is indeed Katerina Eve Campbell herself ?

The second page in particular strongly suggest that

Considering that Cross was revealed to be Cyrus Campbell , it's not out of the realm of possibility that Maria is just him carrying the body of his sister around using Sorcery and using her as a weapon

Idk about you guys, but this part strongly implies that Maria is actually just Katerina. Who is in this weird state between life and death and is only semi-conscious about the stuff happening around her

Especially the fact that Maria appears to care for Cross and Cross even remembers Katerina when Maria hugs him

I have a strong feeling the next chapter is going to confirm this

That next chapter, we're going to find out Maria was Katerina all along. I'm even willing to bet money on it.
