Anti: "I... I-I..."

*Glitch replays the visions over and over in her mind, and a new one comes, continuing the story: *

Beta: "Anyways.  Gaster is working on a way to fuse a human soul with a monster."
Gabby: "Ooohhhh!"
Annie: "A...a human soul?  With a monster?  How will that-"

Her question is interrupted by some sounds that catch her attention.  She decides to check it out while Beta talks to Gaby.

Beta: "We aren't quite ready yet."
Gabby: "Are you positive it will work?"
Beta: "Well, no.  It's still highly experimental."
Gabby: "Highly...experimental...?"
Beta: "Look.  Everything will be okay.  Do you trust us?"
Gabby gulps as something whispers to her: "It's not always good to trust everyone."
She ignores the ominous message.
Gabby: "... yes."

Glitch: "...it's not always good to trust everyone..."
Frisk: ". . ."

A/N: Willing to guess what the noise was, or do you wanna wait and find out?
