Chapter 6
Finn, Jake and Princess Bubblegum were stuck to a nearby wall in an ice trap.
Finn: You mean you guys are the fanatics that worship these things?
Flame Princess: I wouldn't say "fanatics". I would say, "The future of mankind".
Princess Bubblegum: Marceline. Why you?
Marceline: It all started when it was just me and Simon. One day, while we were wandering, we found a Marker. It spoke to us, it said, "Make Us Whole". It showed us the way and enlightened us to Unitology. Now, we await for the day of Convergence.
Ice King: All shall be made one.
Flame Princess: I would have expected Ellie Langford here to know what we worship. You don't think there was a reason I was the first one to get attacked?
Ice King: Or how I was the second one to get attacked?
Marceline: Now thanks to you, we have found the Black Marker, and with it, we can construct Red Markers. The Brethren Moons are coming. They will lead us to a brighter path.
Ellie: You people are absolute maniacs!
Finn: The Brethren moons won't bring a brighter path. They'll just kill everybody.
Flame Princess: That's the point. Once we have all been made one, this planet will join the circle of Brethren Moons. Nothing will stop them.
Jake: We will.
Ice King: You. Ha ha ha! I find that hilarious. Isaac Clarke couldn't even destroy one without killing himself, and he knew how to kill a Necromorph. He even had help from someone as equally skilled, and he couldn't do it without dying either. You two are just little brats. You, Ellie, are the true enemy. You have been a threat to what we stand for since Isaac died.
Ellie: Because what you stand for is suicide!
Ice King: Exactly.
Flame Princess: Looks like we're done here. Let's go you two.
The three of them flew away, leaving the other three trapped.
Finn: Well that's just great.
Jake: Well what do we do now?
Ellie: I don't know.
Suddenly, a grenade flew into the cave, and the shockwave from the explosion shattered the ice, freeing Finn, Jake and Ellie.
Finn: Where did that come from?
Male: Me.
They looked up and saw a tall male in the same suit they were wearing.
Jake: Who are you?
Finn: And why do you have the same suit as us?
The helmet on the suit clicked and slid apart revealing it to be...
Ellie: Isaac? Isaac Clarke?
