UnderSwap Ask or Dare! :D

Revealing

Davis: *he sets Sans down* O-O'''''

Sans: ...Papyrus?

Papyrus: I just looked over and you were in blue mode. I'm just confused as you, Bro. 

Ender: ...I know who did it, Sans?

Sans: Really?

Ender: Yeah. It's about time we told you guys anyway. We'll need everyone here.

*After a few minutes, everyone was at Sans and Papyrus' house*

Undyne: N-Napstaton was busy, so he couldn't come.

Ender: That's alright. Now, Chara, Frisk, I'm gonna need some help from you two explaining this.

*They nod*

Ender: Okay, so... I'm sure all of you know the other six children that fell down here.

Asgore: Yes...

Papyrus: *he laughs* Good times, right bro?

Sans: Indeed!

Alphys: Oh, yeah!

Undyne: Y-Yes, I do!

Toriel: ...

Ender: Well, they're still around... in a way, at least.

Sans: Really?! *he looks around* Where?! I wish to see them!

Chara: That's the thing... you can't. Only Frisk, the Readers and myself can. 

Sans: Oh...

Frisk: They're not able to talk to you, but they can interact with you using magic. 

Papyrus: That's how Sans was put into Blue mode isn't it?

Frisk: You've won the prize.

Undyne: B-But how?

Chara: That part we're not sure about, but we think it has something to do with their SOULS.

*silence*

Alphys: Would there ever be a way to see them again?

Chara: There should be. In Undertale Frisk's ask or dare, they were brought back.
