The comic has Beatrice give several Did You Just Flip Off Cthulhu? and Badass Boast moments.
Beatrice: Yes. For now I understand. You need me. I do not know why. You are incapable of love, and simple lust is something you could force upon any held within your sway. But for some reason, you must marry me. And that means you are not the one with power here. I am.
Lucifer: You will do as I command, woman!
: Of course, for I gave my word. But do not seek to frighten me, Lucifer. Though it surprises me to say, you have no ability to do so.
Beatrice: My god... I understand. You may deceive, manipulate, cajole. You may lie and bargain and trick. But you are as much a prisoner as any soul here. In all the ways that matter... the Devil is impotent. But I am not. In life and death, others have used me for their own ends. But now I have the power to do what they could not. If Lucifer cannot defeat Dante... if Malacoda cannot... I shall.
