Castiel comes to talk to Erica

Erica: Who are you?
Cass: I am more of a what
Erica: Ok I'll bite what are you?
Cass: I'm an Angel of the Lord
Erica: There is no such thing
Cass: That's what your brother said
Erica: Which one?
Cass: Dean
Erica: Ok why are you here and how long have you been standing there.
Cass: For a long time
Erica: You know I can kill you right
Cass: You can't kill an angel with that knife.

Then Erica pulls out her knife

Erica: How did you know I had a knife?
Cass: Remember I am an angel
Erica: So that don't mean anything I can still kick your ass.
Cass: Fine go ahead and try
Erica: Ok don't say I didn't warn you

Erica tries and fights Castiel but he keeps disappearing.

Erica: Come out and fight
Cass: I told you, you can't kill me
Erica: If you bleed you can die
Cass: Fine go ahead and keep trying
Erica: Ok

Again she tries but he just keeps disappearing

Erica: You know what I don't got time for this I got a brother to save.
Cass: Ok
