Charlie Morningstar and Lute were arguing about something

Lute: "Angels don't make mistakes"

She said in a serious tone

Charlie furrows her eyebrows and says;

Charlie: "You REALLY think that?"

Lute immediately strikes back in a serious and kinda angry tone;

Lute: "I know that."

Adam butted in with his usually arrogant tone

Adam: "Yeah! I never made a mistake in my fucking life!"
