Flowey looked eerily distressed when Sans turned to look at him; he had been expecting the flower to stare back at him with either one of those demonic glares or a mocking smile. "I've seen what you're trying to do. It really is funny that you think it's going to work. You can go to the other side of the world if you want to. Chara will follow you either way."

Sans said nothing. Flowey wasn't precisely the one he was willing to seek help from, or even talk to, but he was pretty much the only other one who had the slightest idea of what was going on, aside from him. He could not let the hate put a barrier between him and the small bits of hope there were left. And… It wasn't like the soulless monster would bother mentioning that maniac killing everyone without a reason, however.

"You think that just because you remember what happened in a past timeline, you can stop it from happening again. What a joke." He couldn't help his eyes from widening in surprise. Now Sans was completely sure he needed that flower's help, even though he didn't precisely want to admit so. No, not yet. He had to be fully aware of what that thing knew about other timelines.

"You think you remember what happened? Sure, but you don't know more than I do." A small chuckle. "You want my help, don't you?"

"what do you know about all this."

"Everything, buddy. You may remember what happened, but I remember HOW it happened. I remember every word, every movement, every blink and breath. I saw all Chara had done with help of that other kid."

Sans wasn't about to even question how Flowey knew all that, neither did he know what he meant by that 'other kid', for he had seen only one murderous human on the loose. He just knew that the flower was playing an important role somewhere, and he had to discover where. He sighed, and looked back at his brother, seemingly enjoying the company of several butterflies and fireflies fluttering around him. "you wouldn't tell me this if you didn't have a reason."

"I just came here to state the obvious. You seem way too focused in protecting everyone you love to understand that what you are trying to do is impossible." He burrowed underground and popped out next to the skeleton. "Just admit it and don't complicate your life. With Chara around, you all are meant to die from now on. By trying to get away, you will only lead everyone to their deaths. Chara may as well thank you before killing you, for bringing them all together and make them an easy kill."

With that, Flowey left, leaving Sans alone with a storm of thoughts. He seemed to be concerned about the other child the flower mentioned. Something was off there. One was just about enough, Sans knew he couldn't deal with two psychopaths. Not only that, but Flowey appeared to remember everything just as if it happened yesterday, which led Sans to wonder just how much that little devil actually knew about the past events. He could have made the human remind him about the previous, chaotic timeline, which would lead to the conclusion that they were indeed working together.

"Sans!"

Undyne's voice made him snap right out of his thoughts. He was relieved to see that she managed to save Monster Kid without committing the foolish mistake of fighting something that could not be defeated, but she looked heavily anguished and worried. "If we are leaving, we have to leave NOW." How uneasy her voice sounded told Sans that something was way off the rails. "That punk is already here and is definitely not going to wait until we leave."

The skeleton stood thoughtful for a moment, almost overthinking his next decision. He was bad at making up plans with such a hurry, but he knew what he had to do. "take pap and the kid and go to hotland. tell alphys about this and try to get everyone there to hide."

Undyne blinked in disbelief. "You ain't coming? Are you mad?!"

"no need to worry about me. just get them outta here. i'll be fine." He was gone in the blink of an eye, leaving Undyne momentarily perplexed at his sudden, completely crazy decision. Was he really going to stay there? What if that demon saw him? Then again, he wouldn't get into a fight just like that. She had to trust him otherwise everything would turn upside down. She finally caught her words and almost instantly after realizing Sans would be fine yelled, "Papyrus!"

Said skeleton looked up right away as Undyne hopped off the small hill she stood on with Monster Kid clumsily following, almost loosing his footing, as usual, as he landed. "We need to leave. Right. Now." Papyrus looked at her with wide eyes, but saying nothing. What was with the hurries? Everyone seemed to want to accelerate every single thing.

"B-BUT WHAT ABOUT-"

"RIGHT. NOW!"

Papyrus flinched at the rough tone and didn't even have time to ponder about where his brother was. With Undyne in that mood, the only options were to do what she wanted, or do nothing and have her get whatever the order was done by force. "AYE AYE, SIR!" Papyrus blurted, before frowning under the fixed stare his trainer was giving him. "CAPTAIN? MASTER? ...BOSS?"

Undyne literally growled at him, which easily got him on the move with a small whimper. Monster Kid didn't hesitate to start walking alongside him. "To Hotland. Don't you two dare to go anywhere else."

The scaly hand held the pencil shakily and started writing barely readable letters and numbers down the notebook. Alphys had been completing a few tests lately, and she had been busier than ever trying to fix a few things here and there and getting them to work properly. It had been taking a lot of her time, and she still had to try out a few more improvements before being done.

"Alphys, darling!"

Rather startled, she looked behind her as a noticeably annoyed Mettaton EX came in. "Just tell me we're already done! You are trying to fix perfection!"

There was a slight frown on the lizard's face. After all, it was Mettaton himself who insisted in testing out his new body and Alphys came to the realization that he still needed a few tweaks. "I-I still have t-to… I need to w-write a few things b-before I'm done, alright? It's you w-who… who accepted t-to test out i-if everything was… working properly."

"Fine, fine. Just hurry with that writing! I'm dying to show this off!"

"ALPHYS!"

It truly was a miracle that the lab's doors were automatic or else Undyne would've smashed right through them. Her strenght was threatening to weaken, and her breathings had become slight gasps; she needed to stop a moment to recover after fighting against the inferno Hotland was while at the same time warning everyone to go without asking why. Coming from Undyne, nobody hesitated before getting away.

Alphys let out a startled shriek at the sudden visit, causing the notebook and pencil to fly out of her hands for a second before she caught them both as best as she could. "Alphys, and whatever your name was robot-thing, grab the heck you need and let's get out of here!"

"Welly welly well, hold on just a second!" Mettaton commented before his creator could utter a word, a suspicious and offended tone present in his robotic voice. "First, it's Mettaton for you honey, not 'robot-thing'. Secondly, you can't just come here and tell us to leave. Or at least, you can't tell ME to leave. I have an entire audience waiting for-"

"Shut your mouth, weirdo."

Undyne stomped past him and the robot didn't find the words to backsass the insolence, instead just stared at the spot the absolutely rude intruder had been and blinked once. When he recovered from the lack of respect the star had been given, he merely looked at Undyne with a cheeky scowl.

Monster Kid and Papyrus peeked into the lab with impressed faces as Alphys, having not noticed them yet, nervously asked, "B-b-but what's g-going on? Why- why do w-we have to leave?"

Undyne seemed to be losing her patience. "There's no time to explain now! Just get out of here and I'll tell you on the way!"

The silence was almost too powerful for Sans to handle. It was the sound of death. Nearly every monster living in Waterfall had already been killed as shown by the innocent dust sprawled all over. Those remaining ran away, hid, or even went in search of that devil to avenge the fallen.

He needed to find Flowey. The skeleton never imagined himself doing such thing, but that living flower was the key to anything the little brat had under the sleeve. Sans kept a suspicious eye on how jittery Flowey looked whenever he mentioned Chara's name, as if saying it alone was already a nightmare, even for the all-too-brave plant who stupidly decided fighting a way more powerful monster such as him repeatedly was a good idea.

"Looking for something, skelly?" Sans tried to contain his anger and turned to look at certain expectant flower. "This is funnier than I thought." His face turned demonic as he cackled, "You stay here only to talk to me, even if there's a murderer in the way!"

"quit playing around. you know what's going on here."

"And you want me to help you and your silly little friends." Flowey continued, as if he predicted the incoming words. "Now, why would I do that? I don't see why I should stop Chara from killing you all."

"listen here, buddy." Sans' glowing pupils were gone, leaving a void of pure black on his eye sockets. "you better not play with my patience. i think we've went through this enough times already."

Flowey merely let go a titter at the menace. "It's not like you can get rid of me forever. I can always-" He suddenly stopped, and looked clearly anguished, and even afraid. "I can... always..." Sans frowned in confusion, but luck seemed to get on his side as he overheard the flower mutter, "Her determination... I can't go back to any save point while they are alive..."

"what's the matter, pal?" the skeleton growled, his grin growing further knowing why Flowey suddenly became afraid of a fight against him. He wasn't about to stop and ask what that human had to do with his unability to go back. "can't reset?"

The once careless, scoffing laughs and giggles became nervous. The stem bent downwards as Flowey stuttered, "Hey, I... Think we didn't have a good start, but... You and I are friends, aren't we...?"

A blue flame covered Sans' left eye. He couldn't recall one time in which he had been more serious. "you wish. now, either you tell me everything you know about the timelines and that human, or else, you can already say goodbye to your life."
