It's new character time! Who could it be?
Also, no spoilers, but Cori is trying to make a movie, and her camera is running the entirety of this story, from the beginning until the final chapter, so remember that.

Cori: It's been so long since I've seen you. Days, months, possibly even years. Why have you decided to return here?

Fenton: Uh, Cori? What are you doing?

Cori: Oh, just acting.

Fenton: Well, if you're really acting, what are you acting for?

Cori: Just making a movie.

Fenton: Cool! What genre?

Cori: Suspense and found-footage.

Fenton: Sounds interesting. It'll only be interesting if something suspenseful actually happened.

Cori blushes.

Cori: Shut up! I am keeping this...

Fenton: Whatever you say, Guillermo del Toro.

Fenton leaves the room, while Cori continues to come up with a REAL idea.

Cori: Looks like I'm gonna need reference. Hey, Sylvia!

Sylvia enters the room.

Sylvia: Yeah?

Cori: I need reference for a suspense movie I am making. Any other suspense movies you know?

Sylvia: Disturbia?

Cori: I'VE MADE A MISTAKE.

Suddenly, the door to the base begins to unlock.

Sylvia: Uh oh. Guys, the door is unlocking! FROM THE OUTSIDE!

Cori: (Now's my chance)

Cori quickly goes to grab her camera and begins to record.

Derek: Who could this be?

Cori: I don't know...

Sylvia: Me neither...

The door opens and there at the end is...

Cori: ...a new girl.

?: Hi...

At the end, there is a girl with a top hat.

Sylvia: Who are you?

?: Just here to talk to you.

She points to Sylvia.

Sylvia: Me?

?: Yup, you. I know who you are.

Sylvia: No offense, but it seems awfully unusual that I don't know you, but you know me.

Cori: Can somebody explain what is going on here?

Derek: I don't know either.

Fenton walks in.

Fenton: Guys, I think Cori hit her last nerve- oh heck no I'm out of here.

Fenton walks out.

?: OK.

Sylvia: Back to my statement, who are you?

Emma: Emma. Emma Karaline.

Derek: What are you even doing here... Emma?

Emma: I'm here because I was told to keep watch here.

Cori: Keep... watch...

Emma: Yup. They said you were wanted.

Sylvia: Wanted?

TBC...
