It has been about half a day since Chara "nursed" Frisk in a safe haven of the Ruins. They felt weird about doing so, nothing obliged to take care of yet another human either. Frisk woke up in a leaf bed, along with some veggies and a monster candy.
Chara fetched those because a sleeping child would be famished, obviously, and Frisk could tell by her half-caring, half-maniac glare - like any obsessed girlfriend meme out there. They ate slowly, swallowing some food and some empty out of fear. They remembered being killed by Chara, that one strike that put them down.
Their knife was there, somehow still tainted with their blood, and they were not sure how that fact slipped out of their thought process. The hit was quick and precise, but deadly. The scar left a huge rift going all over their back, from their left shoulder to their right hip.
That sensation of being torn apart by a blade made the candy taste bitter, and the vegs were foul in the mouth. Their flesh remembers being ripped, while bloody red eyes craved more with a black, creepy smile. Chara interrupted thankfully their grim memories with the same voice they had in their head :
"Child."
"You know my name, Chara."
"I do, but that does not matter. Have you slept well?"
"I feel peachy now, but I'll need to lay down some more." Frisk was ironic, they could hardly move a muscle.
"Please do not take too long, I do not wish to strike more monsters, or you for that matter ... it feels wrong somehow." said a worried - and not admitting it yet - Chara, half glancing at the child.
"Chara?"
"Yes Ch- ... Frisk."
"How come you did not kill me?"
"I do not either, I thought I did ... I thought I did lose someone else again -" The Fallen whispered the last bit, surprised at their thoughts.
"But I'm here, after hearing your friend. He looks like your mother." Frisk tried to comfort their killer, without knowing why either, it felt like the right thing to do.
"I do not want to talk about that yet ... but I guess you being alive is something I know of."
"Care to enlighten me?"
Chara had to explain the whole process of SAVEs and RESETs, along with the memory loss that implies those. They pointed out that they learned about it only after their death, but that Frisk somehow had access to it. That did not mean there was no perma-death after all, as Chara lacked the Determination to live to use that power. They could only rewind their memories to them poisoning themselves, a few minutes before they passed out.
As Chara went on explaining, Frisk had something to say before they continued listening :
"What about your melting face?"
"That ... is the twisted me. They kind of take over when I am ... well ... onto killing"
"So you ... don't remember killing me?"
"I do, I do not know why! All I know is that my knife should have saved your life and not dropped you lifeless -"
" - but I wanted to save the monster -"
" ... who was about to beat you to a pulp? and I thought you had enough pain history. Are you an M or something?"
"M ? what is M - wait, no! I'm not enjoying those, I just wanted to exit battle mode without fighting the monster -"
" - Which is near impossible if you do not get their patterns, Child. You need to get your shit together."
" My name is Frisk, please use it and ... Thank you for taking care of me, although you should stop the badmouthing .said Frisk, who could hardly argue in their surprise, to say the least. The Child they murdered - albeit accidentally - is taking time to thank them in the middle of an argument. They got up and fled from Frisk who gave up talking further and slept some more. They cried more than they should, their eyes fully red now.
Wandering in the ruins, and dismissing monsters with their dark half, they arrived at a table. There was a piece of cheese, stuck in what appeared to be a crystal with a color that mirrored the ruins. Seeing that strengthened their resolve, although they doubted the cheese would be any edible. The thought of mice waiting for the crystal to melt pulsed in their SOUL, filling them with Determination.
Chara thought of Frisk and decided to return to the haven before they woke. Yet, when they got back, the Child was gone. Their heart ached at Frisk's disappearance, but soon a voice growled deep inside:
"See, just another of those pesky beings you fought in the past. Let them go, let hatred be yours once more"
A voice they shunned away by crying louder, sniffling a bit, and then went looking for Frisk, who a couple of rooms further met a ghost laying down. Their seemingly blocking the road bothered the Child, which tried to pass but saw his red heart pop up. Frisk met a ghost who was visibly depressed and could start weeping any second
"I did not want to fight that one either ..." said the Child, readying themselves to comfort and dodge bullets again
