Fire and Water

[NOTE: s. Ogon is an old fire, s. Voda is an old water (from 2009, like the past)]
It's a sunny day in 2009. Fireboy and Watergirl were going through the final level of this temple! But no... it cost Fireboy's LIFE!
When they walked through the doors, they realized there was simply nothing. No exit, no rooms, no light, nothing at all, just emptiness... the only thing that shone was the Fire.
In how many hours:
S.Ogon: "O-o-o-o-yes... I'm tired, we've been walking for hours and there's nothing... let's sit down?..
S. Voda:: - "Wait, Fire! I feel it coming out somewhere nearby!"
Before she could even move away from the Fire, she heard "BAM". Looking back, she sees the Fire just... sitting?.. It's not tired... It's just... going out...?
S. Water - "Fire, are you okay!? Wait! There should be lava, fire, or something else here!..."
After a few minutes, realizing that nothing was inevitable, Fire simply asked to be told how the horses had passed the first level, and then simply went out.
Finally, it's 2025... because that's where the sequel began... New copies of Fire and Water have appeared. Level 45... Walking through the temple, Fire noticed something strange...
Water: “Fire, let’s go already!”
Fire: "Water, do you know why this level was passed?" he said, pointing to one of the doors.
Water: “Wow.. I don’t know.. maybe a ghost?”
Having entered this door, they heard the words of S. Voda.
Having found S. Water and gotten acquainted, S. Water first said, "You choose how to spend the last minutes of your life," although it wasn't entirely clear what she meant. Having settled down on the floor, Fire and Water began asking a LOT OF QUESTIONS, for example: "What was that green goo just now!?" but she only answered the first one.
S.Water, Fire, and Water began to fight this evil sludge. When he answered, they found the REAL exit. S.Water sent them outside, saying she would catch up with them, but her goal was to finally kill this green scarecrow. *

• After defeating him, she notices some kind of portal, then comes out of it. Fire? .. It's a different fire. S.Fire... The same thing happened in another universe, only it wasn't S.Fire who died, but S.Water.
