[Frisk]
As I walk forward, I see an old friend
Someone who I loved in a different end
Knife is stained red, blood of all my victims
Full of regret, someone stop these symptoms

I don't want to, it's not right
But a force is compelling me to fight
Ready my knife, though it's not me
There is something taking over

But nobody else is here
Sans is the only one that is near
I guess that it means that it's my fault
I brought all their lives to a halt

I deserve all that happens
I caused еverybody to die
I should not be forgivеn
I'm dreading this fight, I can't kill anymore
He's coming closer, please someone help me!

[Sans, spoken]
So, i've got a question for ya. do you think even the worst person can change...? that everyone can be a good person if they just try?

Heh heh heh heh... all right. well, here's a better question. do you wanna have a bad time? 'cause if you take another step forward... you are REALLY not going to like what happens next
Welp. sorry, old lady. this is why i never make promises

[Sans, sung]
Hey kid, what's with that expression?
Is this something you expected?
Or is this something you wanted?
Something that you knew would happen?

Did you think I didn't notice?
Let's go, no need to regret it
Just don't look so shocked to say it
I was watching all of this

Were you once a human being?
You're not any longer so it seems
As your heart fills up with EXP
Your LOVE's worrying me

You got caught on numbers, kid
It's all about the high score, isn't it?
You knew what you wanted, this was not an accident

Now you're not a problem that I can ignore
Not fed up, but you're triggering the flags
I can't sit back, not anymore
Wonder if I've done this song and dance before?
Guess it's something that I better look towards
Even after everything, he still believed
You could be just a little better
And you might turn back, but now I see
All of that was just what I wanted to think
You know that you never want it easy

[Sans, spoken]
C'mon buddy. do you remember me? please, if you're listening... let's forget all this, ok? just lay down your weapon, and...

Well, my job will be a lot easier
...guess we're doing this the hard way then

[Toriel, Papyrus, Undyne, Alphys and Mettaton]
It's a beautiful day now outside
Birds are singing, flowers blooming bright
Days like these should be full of light
But kids like you should be burning in
HELL!

Human, are you ready for
A fight between all of us together?
Will we get to our revenge
Or will you get to the end?

In your smile and in your eyes
They're showing the real monster that's within
Killing us all one by one, you feed it LOVE as you win
Hey, tell me, do you wanna have a bad time?
Do you think we are really gonna stand there
And let go of all of your crimes?
Feel all of the sins crawl up your back

Sans's power allows us to work through him
Fighting for our final revenge
Will we get our last, huge wish?
Your determination needs to die

Was it worth the cost?
All our lives that were lost?
We warned you, can't you see?
You chose to let us bleed

Every being
Fighting all as one now
Want to stay as friends?
Then don't come back again

[Sans and company]
GO, JUST GO!

[Toriel, Papyrus, Undyne, Alphys and Mettaton]
Full of frustration, are you now?
I guess our fight is going well somehow
If you try to go back to the start
There will be no change inside our hearts

Are you still having your fun?
The time has come, there's nowhere to run
Now feel the endless agony
This is a reality!

[Sans]
And I know...
You'll put me to an endless sleep...
