Marc: Well what should we do now? We can't let him in my house like that!
Iris: But Marc! He's dead! We can't do anything now!
Tanya: You said we can't do anything? Well speak for yourself! Because someone have a time machine! But first here's the plan!
Marc: Okay Tanya! Shoot!
Tanya: We need to go in the past and bring this spirit inside of Mephisto mind so he can be able to be a good guy and be against his twin sister for good!
Marc: Before we do that, I want this guy stay with us!
Iris: I don't like this idea at all!
Marc: Alright men! You want to revive?
Mephisto: What? You can revive me?
Marc: Euh yes! By removing the evil spirit in your mind! Once you are in your body, I want to you to be against your twin sister!
Mephisto: It's that very necessary to do this to her?
Marc: WHAT OTHER CHOICE DO WE HAVE?
Mephisto: I guess I don't have any choice! After that, you're not gonna eat me right?
Marc: Of course I won't eat you or beat you up!
Tanya: Let's go see Stewie for this!
Later...
Brian: Oh hello Tanya! What's bring you here?
Tanya: Well we need to go back in the past and do something fast!
Stewie: Well let's go then!
Marc and his gang go through the past.
Marc: Here's the fight scene!
Tanya: Alright! Brian and Stewie, stay here! Marc release the spirit!
