*The two sisters are still frozen*
*Gaster's ominous presence is...well, present, as he nods to GoldShard/Koda*

Anti: "I... .... ... Dr...WingDing...Gaster... where...where have I heard that before?"
Frisk: "GUYS..!?"

The group walks into the lab.
Gabby: "So what do you need help with?"
Gaster: "If you don't mind, I need a few test subjects."
Gabby: "Ooh, that sounds fun!"
Annie: "D...doesn't it seem dangerous though?"
Gaster: "I understand if you don't want to do it.  But it would help me out a bunch.  It would also help out King Asgore."
Annie: "Well, if it's for the king..."
Gabby: "Where do we begin?"

Glitch: "I... I...don't...understand..."

A/N: Oh, I think I see where you're going with this.  Clever.  Things are getting pretty intense, hm?
