The Overlord, The Automata, and The Silver

Hey guys, so I realized something. I don't know how to write Aeskell. I know how to write Ainz, I know how to write Albedo, but not Aeskell. though, she is a original character that I wrote on a whim, so that's fine. But, her personality has kind if shifted all over the place. first, she was analytical, then she was kind of emotional and there to be a support, but now I've just had her make references to Hellsing abridged, and kind of be dick-ish. So, how do you want her to act? What do you think makes the most sense?
