Look above forgot to ping sorry

Topaz:"hate yo break it to you,she can't the doors locked. I've tried. Teleporting doesn't work.Only way is to portal out."

Wonder!Chara:"I can ask harligh!" she looked at the wall."nervermind" she backed up

This one was probably the man Abby had told her about, Elia thought. It looked more like the idea she had of a mage and scientist experimenting with timelines than the young boy did.
She decided to walk toward him to introduce herself.
"My name is Elia. Nice to meet you. I guess you are the one who had made experiment with time?" she asked her.
Thalie glared at her cousin. Elia realized she had forgotten once again to introduce her. She had not even finished her chocolate bar, why did she care? She could introduce herself, she was a grown woman!
"The blonde girl here with the mouth covered by chocolate is my cousin Thalie." Elia added to the man with a smile.

Gael felt a little bit stupid. Of course if Kaea did not know what movies were, she did not know what a cinema was.
"Sorry. A cinema is a place we go to watch movie, like I could do on this TV here, but in a cinema the screens are very large, taller than this the walls of this room." he explained.
Gael had turned on the TV to show her. Of course, at this time, there was nothing more interesting that the news and some boring TV games shows.
"Don't you have anything more interesting to show her if you want to show Kaea what a movie is?" said Florie.
"Like what?"
"I don't know, anything but that. What kind of stories do you like, Kaea?" asked the girl.

"I conduct experiments with time, so i believe you are correct. Pleasure to meet you aswell." He looked at Thalie, and nodded slowly. "So, why have i been asked to come here? This will certainly take time that i could have used to wrap up experiment C33121. Though i suppose it wouldn't matter much." He trailed off clicking his tongue. Hmm, now isnt this interesting, i never knew about this place before. This isnt that useful to know but its interesting he thought. Frisk stared at Nexus curiously, and Chara groaned inwardly. "How many people are gonna pop up here?" she said quietly. Nexus turned his head in Abby's direction, and silently adjusted his cloak again. "Charming creature" was all he said to her, of course Frisk had no clue what that implied. "Oh, parden me i never told you my name, its Nexus" he said to Elia and everyone who intended to hear in earshot. Abby took on a strange look, secretly analyzing the mage. so he knows? How odd, usually nobody does untill its too late. Well i cant expect this disguise to work for every manner of creature, and i cant say im surprised he knows. Hes a counsel member after all, i should've realised before.. Abby thought glancing back at Frisk. Flowey tapped Frisk's head, and he looked at Flowey curiously. "i think you should keep an eye on that girl, shes been staring all this time and its starting to freak me out. We dont know if you can reset here,
So be careful" Flowey said in a hushed tone. Frisk nodded.

Elia was confused. She had no clue what experiment C3... C3 something was, and dit not understand all that was going on between Abby, Frisk, Flowey and Nexus.

"You are here because my cousin wants to change history. I am sorry about that, and I want you to know that I have nothing to do with it". explained Thalie before biting on the chocolate again.

"It is true". confirmed Elia. "More exactly, I want to save some people who are condamned to a terrible fate and die according to history books. But I want to try to find a way to do that without errasing our history entirely. I... I would like to know if there is a way to create a parallel timeline or world where they could be saved."

Again, child, you are underestimating her. Reflection sighed, really not wanting to deal with children right now.

"Change history? And create a parallel timeline?" He chuckled to himself. "There will always be a timeline where they die, and another where they live. They will always exist, and theres nothing you can do to change that. However, if you intend on saving people in a certain timeline that is different. Now, if you have the means to travel back in the timeline, and save them before their deaths, it would be simple." He cleared his throat. "If it doesnt effect the passage of time, and the history, theres only the possibility of anomalies. You would have to save them without being noticed, they should be dead in the eyes of the people involved. That covers not changing history." He looked around, presumably for a place to sit. Unsatisfied with the choices he continued. "Theres a chance you could cause something otherworldly to occur, and theres a chance nothing will happen. But if you dont actually try and change the course of time and the timeline all together i see no problem. Creating another timeline however.. could and probably will cause 'errors'.. if you do it wrong. To avoid that whole genre of problem on its own just do as i said. If it doesnt effect people's perspective on history its fine. But if you want to save someone significant like a king or someone reknown it will be a little harder to conceal the fact that they didnt actually die. So, in conclusion, you can fake their deaths and they can live out the rest of their lives in your time or theirs in secret. Or just somewhere no one knows them. Theres already a world out there where they have not died, but i suppose the world you have met them and affected is what you desire to save." He let out a long sigh, saying that much made him run out of breath, but he couldnt say he didnt enjoy it.

"I want to save the ones I know. So I guess it means that I have to save them our timeline".
She paused.
"I have the mean to go back in time. I would not have met them otherwise".
Elia looked uncomfortable since he had mentionned it would be harder to save a king or someone significant, and she was playing stressfully with her ring. Thalie had only turned her face to look away from her cousin at this instant.
"None of them are a king." she explained in a bitter voice, both sarcastic and sad.
She had a smirk that looked a bit forced on her face.
"But...", she continued with a soft voice,"saving them would change history, to an extent is not possible to imagine. It might change it only a little bit if history corrects itself in one way or another. It could also change everything. The second possibility is the most likely to happen."
Of course, it was tempting. To accept his offer. To prevent their death. To create a world were she would be a beloved and famous historical figure. But she could not take the risk to destroy everything.
"How can you simulate a murder?" asked Thalie in an ironical voice.
Elia glared at her menacingly. It's not funny at all. Please don't, she was thinking.

Nexus listened and narrowed his eyes at Thalie's comment, this could not be seen because of his mask of course. "Well, it really depends on the time period or technological advancement of the era of which you plan to do it. But you have to weigh in all the factors aswell. The time, the circumstances, the method of which the person was murdered in.." he cleared his throat. "I really cant help you further if i dont know the details, tho that is personal information, of which i have no right to know. You may choose if you want to tell me or not." He finished stepping back a little. He sighed "sometimes its better not to get attached, every life comes to an end at some point.. normally, sometimes not.. do what you see fit, i shall go now." He turned and opened a portal, it seemed like the very fabric of reality was torn open. He started towards it, Frisk watched curiously and muttered "shortcut..".
