Patty: Spengler? Hell kinda name is Spengler?

Erin: Is that a first name or last name?

Jillian: Last. First name, Egon.

Abby: Wait, you’re Hungarian?

Jillian: American. But not exactly from here. I was a Ghostbuster like you in my former life where the year is still Nineteen-Ninety-Six of a different world, but now I am here in your world to deliver a dire warning of wretched demons that are threatening to arrive. Dead souls with an evil temperament from my world are gathering with those you have apparently already banished from this world. What they wish to bring is Hell to both my Earth and yours. I have fought this battle in spirit form. I have refused to cross over until this war has finally been won.

Patty: Wait, what do you mean “cross over?”

Abby: I’m guessing that’s the afterlife.

Erin: And why can’t you get away from Jillian???

Jillian: Because I lost my voice. In order to relay my message I need a conduit.  I am peaceful to you and this team. I will be in need of you to destroy the demons that threaten us. You will be in need of myself as well. My team will be in need of you. You will be in need of my team. They can still bust ghosts. Collectively we will need to work together or both our worlds will be doomed. I’m working on being able to transfer the living from one universe to the other in order to fight these battles. Be ready. Be vigilant. You still have time to prepare for Halloween.

Erin: Excuse me, did you say ”Halloween?”

Jillian: That is when they plan to strike.

Abby: Let me get this straight! You’re possessing Holtzmann to tell us about a bunch of demons that are gonna get together and destroy us and some other Earth in another universe? On Halloween?

Patty: Why they gotta choose Halloween? Man, demons are buzzkillers.

Erin: All Hallow’s Eve. It makes perfect sense. Traditionally that’s when evil spirits rise up in an effort to corrupt the living. It’s the night before All Saints Day when the evil is cast out.

Jillian: Correct. These ghosts want to capitalize on a night too many on your world and mine alike perceive as the most evil. I’m delivering this warning now so that we’ll still have time to plan our defense.
