You wake up after battling Asriel Dremurr, the barrier was now broken, meaning monsterkind could finally return to the surface

[Toriel] : * "(Your name)... We do not remember exactly what happened. There was a flower... And then a blinding light covered our vision, but now the barrier is gone. When you are ready, we will all return to the surface, it seems like the door to the east will lead us there now, but before then... Perhaps you may want to take a walk?"

[Sans] : * "Say, Actually, (Your name), Could you do me a favour? Meet me and Alphys in the throne room if ya can." (He walked into the throne room)

[Alphys] : (Sans, are we really going to get the human involved with this!?) * "W-Well, I should go with Sans if he wanted me there too." (She also walked into the throne room)

[Undyne] : * "You better go help her, punk!"

[Asgore] : * "How curious..."

(The monsters continued to talk as you followed Sans and Alphys into the throne room)

[Alphys] : * "Sans, are you really sure we should get the human involved with this?"

[Sans] : * "Yeah, it'll be alright. (Turns to you) * * "So, y'know how Alphys had all of those melted monsters? Well, right before coming here, she called everyone's families and sent them back, that was except for one of them, Kanako, she did try to contact her mother but there was no answer, so she kinda needs your help to safely bring Kanako back to her mother"

[Alphys] : * "Yeah, could you help me with that? I don't blame you if not though, another adventure would probably be exhausting."

(You agree to help Alphys)

[Alphys] : * "Thank you, (Your name), That means alot, let's go to the lab now, Martlet should be waiting there."

(You went to Alphys's laboratory, outside was a tall blue bird lady)

[Martlet] : * "Dr Alphys! It's been so long, how are you?"

[Alphys] : * "Me? I'm fine, also, this is (Your name), they're a human!"
