In "The End Part One" even while Raven has accepted her fate and the end of the world, she still manages to take out some of her anger on Slade as he escorts her to the chamber in which she is destined to summon Trigon to Earth. She speaks to him, with a kind of bitterness you don't ordinarily see in Raven, and demonstrates that his own army shows more obedience to her than him. And her demon mode is on during this whole exchange, amplifying the sheer kickassery.
Raven: You're a fool. Whatever he promised you, he won't deliver.
Slade: Dear child, you don't know what you're talking about.
Raven: You think I don't know my own father?
Slade: You are merely the portal. An insignificant pawn in Trigon's game.
Raven: Then I guess we have that in common. And once he gets what he wants... you'll be insignificant, too.
Slade: Shut your mouth! (His minions grab him) Get off me! Do as I command!
Raven: Come to think of it, Slade, you're already insignificant. Even your own army won't listen to you.
