Mortal Sins examines the motivations of the characters in this episode with a flashback analysis of episodes 1-4. Lucifer, Maria, and Levi all have different needs and desires, but they still came together as a team to help fight the Mortal Sins. There's plenty more to come.
I'm going to defeat you, and from now on,
Ich werde euch besiegen
und fortan werde ich, Luzifer,
Te venceré y desde ahora,
Te venceré y desde ahora,
Je vais te vaincre.
Aujourd’hui, la grande Lucifer
Io ti sconfiggerò, e da questo momento in avanti,
Vou te derrotar e, a partir de agora,
Ты падёшь, и с этого момента, я, Люцифер, 
встану во главе Семи смертных грехов.
