Guy in Black Cloak emerges Protagonist

Protagonist: "Whoa, dark clothes, menacing aura, oddly cool black cloak? He's clearly a bad guy."

Black Cloak: "Wait what? Hold on, I'm-"

Protagonist 2: "Oh shoot, he's probably one of the generals the minions warned us about!"

Black Cloak: "Hold on, I'm trying to warn you-"

Protag 1: "To give up and cower at your might? Never!"

Then a white blade carves through Black Cloak.

White Knight: "He was trying to warn you about me."

Black Cloak: "Protags," holding on for dear life, "run."
