Released to celebrate 100 total visitors. I admit, I didn't think I would get to Chapter 4 when I started. Mostly because I was thinking extremely short-term. Well, here's Chapter 4, anyways.

D. Va explained. 'The flower can kind of 'dig' underground. I'm not sure how it works, but it does.'

Frisk elaborated. 'He can go wherever the hell he wants, and uses it quite often to kill people.'

'Ah, I see. A genocidal flower.' Winston replied.

'Er- yeah. Close enough. He's killed me plenty of times, certainly.' Frisk realized they'd said too much.

'Wait… how are you alive, then? Because resurrection is Mercy's thing, and I don't recall her going down a cave to help you.' Tracer asked.

'I certainly didn't do that. Unless someone else could devise a way to bring people back from the dead, you can't have been killed.' added Mercy.

'Er… well, there's something called Determination, which can revive people, given that their Determination is strong enough...' Frisk stuttered.

'Ok… but how does Determination work, exactly?' enquired Winston.

'I don't know, I'm not a Determination scientist! Ask one of them.' Frisk was careful not to say 'Dr. Alphys', since then they would ask some more questions, and that was kind of stressful, answering them. They were a kid, in front of 5 apparently fully grown people (and gorilla). You can imagine how that went.

'Ok, let's go, then.' D. Va said impatiently.

They suddenly found a room of a musty shade of pink, derelict with an air of being neglected for years, maybe decades. There were 6 buttons on the floor, and a switch on the wall. There was a locked door beside the switch.

'Press the buttons,' Frisk and D. Va instructed. Genji poked a button with his sword. It sprang up immediately. He tried another one, and this time it stayed put. He tried the same thing with the other 4 buttons, and 3 stayed down.

Frisk flipped the switch on the wall, and the door opened. The next room had 2 bridges over 2 separate rivers, with a switch between them, and 2 more past the 2nd bridge. There was a pair of spikes at the end of the room. 'Press the marked switches to get rid of the spikes.' Frisk said.

The spikes retracted upon hitting the second switch. The next room had a dummy in it, and a doorway.

This time, D. Va spoke. 'You have to 'encounter' the Dummy, because things can attack you down here, and you need to be prepared.'

'Wait… how do you know all this?' was the reply from everyone, including Frisk.

'Well, I think we might have fallen into a video game. The one I was playing 10 minutes before we left. Undertale. No offense to you, Frisk, but you live in a video game.'

(Everybody spends 30 minutes contemplating what D. Va just said.)

'Oh.' was the general response after those 30 minutes.

'Well, should we, er, practice on this dummy, as you said?' Tracer eventually said.

D. Va answered. 'Sure. Let's do that. Do you remember, Frisk?'

'Yeah. Sure, let's start.'

Well, I'm finally done this chapter. It took longer than I expected, mostly because I kept getting sidetracked. Chapter 5 on Wednesday (May 30). (539 words)
