Hello Again, now some of these were very unclear and I had no idea what they meant, but I managed to write it all down so, here it is.
AngelMaster14, asked: If you guys are on the surface how is life there. If not how is the Underground?
Asriel: It's been great since we left the underground, actually. Everyone has their own lives now, but we all live in the same area, so we see each ther often. Frisk you wanna take over?
Frisk: Sure, thanks Azzie. Yeah It's been better than ever, Azzie and I have got our own house, and everyone is nearby. Chara makes, 'apperances', from time to time and she is now less, murderous towards us which is always good-
Chara: Are you talking about me behind my back?
Asriel: Wait, I thought you were with sans.
Chara: Ugh, he's so boring-
Sans: What did you say!?
Chara: Oh, you wanna go!?
Sans: Do you wanna have bad time? (eye lights up)
Chara: You think that'll stop me.
?.?.?: (Starts playing Megalovania, as a fight starts with them all)
dream1990: chara is coming for me, i am afraid what them/their will do to me once chara finds me.
Chara: Oh don't worry, I won't kill ya, I'm just gonna rip out your soul and use it to feed my power, while you fail to remember who you were, walking around for the rest of your life, not knowing what you are. You will be trapped in an endless cycle of torment and dispair. That doesn't sound too bad, does it?
"I have gone through many a timeline, fighting the many versions of a glitched out mess of a creature known as Error Sans. I know Frisk doesn't need the whole thing to live and feel. Soulless Pacifest Run is what the circumstance such a Frisk is in is called. Since this Frisk is in that situation, I want to help. My intent is to return the soul to Frisk so he will once again be whole.
In my crusades against multi universe threatening evil, I have defeated and contained many wicked anomalies. In exchange for this Frisk's soul, I can give you one of mine. I don't feel like taking it by force." Alchemy's explained, a bright red soul appearing in his right hand.
Chara: Hmm... So you're saying, if I give you a piece of Frisk's soul both of them will live and I get a soul in return. Also, who is this 'Error Sans', is he like a rouge, genocidal version of our Sans. Wait, I know who you're talking about, at least I think so. Not to say the sans I saw in the royal hall was any different, but this guy sounds cool, when can I meet him? That doesn't matter now, what matters is you giving the other Frisk a soul, our Frisk's get's a new one and you kill that bast- ... Error sans. I'll take the offer.
Sans, i'm the brother of Bill Cipher, the other Sans didn't stand a chance against him. I'm a highly respected chaotic neutral dream demon that doesn't fuck people over with deals, you don't intimidate me.
Besides, Alchemy's been killing stronger versions of your entire race for a million years. And he hates Sanses everywhere, he wouldn't stop me from killing you.
Sans: ..., ... I'm guessing you're talking about the me who tried to kill Frisk, I remember that like it was yesterday. *Far away shouting from Frisk to sans*. Yeah, but what about all the times I killed you first.
?.?.?: Sans, just calm down, you only need to answer the question.
Sans: Yeah, you're right. About the load's, Yeah I still remember them, each one I can't forget, even when I wanted to. It really did break me, I was willing to do anything to get out of it and even if I died trying it would all just reset anyway. Even though, the only way to get to the surface was through Frisk not being a genocidal maniac-
Frisk: I can still hear you!
Sans: I don't care Frisk! But anyway If you want to kill me, fine. If Alchemy want's to kill me, fine aswell, but you're gonna have a bad time doing so. As for the theory, yes it's true. But only for a few me's.
That's all I got through today, but keep asking and I'm sure these guys'll keep answering. See ya!
