Asriel chased Chara through the Core.
-Try to catch me!-
She disappeared in a turn, running through labyrinth of futuristic corridors.
-Chara! Come back here! It's not funny!-
Asriel whined. He caught up with her only when she stop at an edge, nearly falling into the lava.
-Wow! It's edgy here!-
Asriel said, colliding into Chara. Behind them suddenly appeared (literally) Doctor W.D. Gaster.
-You two better stop running in this part of the core! If anything happens to you, your parents will turn me into dust!-
He said, a hard accent audible. He was still trying to learn English, since there were barely any people who understood Windings.
-Sorry, Dr. Gaster.-
Asriel squeaked. The royal scientist sighed loudly, slight smile on his face.
-Children…-
Suddenly his phone rang and he answered.
-Hello? Oh… Oh, yes, your majesty. They are in The Core… Oh, now? All right.-
He hang up and put the phone into his pocket.
-Kids, your mother needs you immediately home.-
He said. Both Chara and Asriel groaned in disappointment.
-But we only started exploring!-
Chara complained.
-Sorry kids, you can come to the end later. Now let me bring you via a short-cut to your home.-
He placed hands on their shoulders and suddenly, in a moment, they were at their house. Both nearly passed out from this "short-cut". Gaster did it pretty often to them and they never understood how was he usual to it.
-I hope to see you two after your lesson tomorrow, but you shall learn to be more careful! Safety barriers on the bridges aren't done yet, you may fall down if not careful!-
Waving, Dr. Gaster went away, teleporting behind a corner. Chara and Asriel, after waving back, entered the house just to meet their mother's gaze.
-Children, your dad fell ill today.-
She said. Asriel all shuddered.
-Really? How? Why?-
He asked nervously.
-The symptoms look like poisoning by buttercups. What I meant to say is that dad won't take you to learn about Echo Flowers tomorrow .-
Chara looked disappointed only by missing the fun lesson in Waterfall, unlike Asriel who started panicking.
-Buttercups? Chara, it's our pie!-
He whined. Toriel frowned hearing this.
-Pie? The one you gave dad yesterday as a present? Did you add buttercups?-
She asked in firm voice.
-That's what he told me to add!-
Chara pointed at her step-brother. Asriel got frightened.
-T-that's what was written in the recipe!-
He mumbled, his voice starting to shake. Toriel's eyebrows crawled onto her forehead.
-Buttercups? In the recipe?-
She led them to the kitchen and tookout the recipe.
-Where is it written?-
She asked, handing it to Asriel.
-H-here…-
He pointed. Chara looked from behind his shoulder.
-Azzy! It says "cups of butter", and not buttercups!-
She noticed. Toriel crossed her arms.
-Asriel, you know I forbid you to bake without my watch. But well, I won't get mad because of that, because Chara knows to cook. But if you wasn't sure what did the recipe say, you could've asked her or me. And Chara, Asriel is younger than you. You should have checked that he is correct. And I assume you both know that buttercups are poisonous.-
-I'm soooorry!-
Asriel started crying. Chara sighed. Asriel was such a crybaby, even when it wasn't too serious. Like now, he didn't kill anyone, just confused cups of butter with buttercups, but he whined as if he murdered someone.
Under Toriel's serious gaze, Chara understood that she's waiting for an apology.
-Sorry mom, I'll be more responsible next time.-
She said, barely actually meaning it. Toriel sighed loudly.
-Tomorrow I'm taking your dad to Doctor Alphys for the medicine, so you will be allowed to continue exploring The Core under Dr. Gaster's watch. And when your dad will feel better, owe him an apology. Am I clear, children?-
Asriel nodded frantically. Chara shrugged slightly as "whatever".
-Now, Chara, you go to your room and think about being more responsible this time. Asriel, you go too. Let Chara train with you reading.-
Toriel turned around and started walking towards Asgore's room, what raised a question in Chara's mind.
-Hey, mom? Why do you and dad sleep in separated rooms?-
She asked out of nowhere. Toriel stopped, her face still serious, but a light glance of amuse appeared in her eyes.
-Because he snores.-
She answered shortly and went away. Chara laughed about this and also about the view of Asriel desperately running into their room. With a sight, she followed him.
-C'mon, Azzy, it's not so terrible.-
-It is! It is terrible! We poisoned dad! It's all my faaaault!-
He dropped onto the bed, crying into the pillow. Sighing, Chara pulled his book from a shelf.
-Don't you worry, dad will be fine. Let's just practice your reading now, so next time you won't confuse ingredients.-
She said. Meanwhile, she actually was thinking of something else. She knew how to make her wish to free the underground come true.
