[Future mishap]

*Exits through her silver portal in the office* Alex, Beans I'm home. *Sees the ZG Cipher twins*

Will: Oh, Miss. Yang!

Bill: Hey Swift!

How did you guys get here? I didn't leave any portals behind, did I?

Bill & Will: Uhhhh...

[Earlier that day]
[Zero Gravity]

*Wounded* Out of fields. *Opens her portal and jumps in*

Bill: Jackpot, the portal. Come on Will.

Will: But won't Miss. Yang find out?

Bill: Nonsense, she's too busy protecting our home. Now let's go. *Jumps in*

Will:*Hesitate* *Jumps in*

*Jumps out with more biotic field emitters* Now you Haters are in my sights.

[Present time]

Bill: That's how we got here. I never knew this place is awesome!

Okay yeah but you didn't snoop around right?

Bill & Will: Ehhh........

Kill: These things are awesome!!! *Runs around with Graze's shotguns*

Kill!

Kill:*Accidentally shoots Swift*

Bill & Will:*Gasps in horror*

*Losing blood* You idiot. *Fell on her knees*

The Triplets:*Freaking out*

Will: I knew this would happen!

*Gasping for breath and quickly sets a field up* *Healing* Kill...

Kill:*Afraid* Yes Yang?

Come closer.

Kill:*Walks closer to her*

*Punches him* That's for shooting me dumbass!

Kill: You startled me!

You fooled around with my boyfriend's shotguns! You're lucky I didn't get my sights on you and shoot your ass! You immature- *Headlocks the red head*

Bill & Will:*Tries to break them up*

Graze:*Shadow steps in the room* Hey hey! *Tries to pull his girlfriend away from Kill* What's going on? What happened?

Kill started it!

Kill: She tried to break my neck!

He took your shotguns!

Graze: Who's fault for opening the portal?

*Stops resisting and raised her hand*

Graze: Thought so.

But I needed more emitters from my last fight.

I told you before, you need me.

Bill: May we leave? I think we caused enough trouble.

Graze:*Creates a golden portal*

The Triplets:*Leave*
