Bobby: I know I am not your dad but I think you should find a way to help him.
Erica: I am going out

Erica leaves Bobby's place

At a crossroad

Erica: I hope this works

Just put the box in the dirt road

Erica: Come out you little bitch
Demon: Well that is no way to talk to me
Erica: I heard that you are the one to help me for something important.
Demon: Yeah what is it that you need miss. Winchester
Erica: I know that Dean is going to hell and he would like to get that demon out of Sam before his time is out.
Demon: So what you are saying is that you would want to take Dean's place.
Erica: Yeah can you do it?
Demon: Yeah but you still need to sweeten the deal
Erica: What would you like me to do
Demon: When the demon is out of Sam you can't come after me that goes for your brothers too.
Erica: Fine so what do we do?
Demon: This

The demon kisses her

Erica: Ok so how long do I get
Demon: 1 year only
Erica: Fine
Demon: Ok

Then the demon left
