A/N: Sorry for the short chapter. There will also be Sans talk, meaning slang like 'ya, and gonna.' Just a heads up.

"Sans!" A small, genderless child yelled when they came through the door to a certain two skeleton's house.

"Sup, kid?" Sans asked. He was lounging on the couch, drinking a bottle of ketchup.

"I went to visit Flowey, and just before I left, he told me he wanted to see you."

Sans almost spit the gulp of ketchup he had in his mouth out. "The flower wants to see me?" Sans asked in surprise.

"…Yes." Frisk answered, disappointed that Sans couldn't just get along with Flowey.

"Kid, you know that Flower and I don't get along very well…I don't think I should go." Sans kept making up excuses to not go, but Frisk wouldn't have it.

"Pleeeaaasse?" Frisk pleaded.

Sans knew he couldn't say no to that face. "Fine, fine. I'll go."

Frisk squealed and bounced on her toes in excitement that her face convinced Sans to go.

"I'll be waiting here!" Frisk said.

"Sounds good." Sans got up, walked to the door, and left the house.

He stood outside the door for a minute, thinking, 'What would that little weed want with me?' But Sans put that thought aside, for he had already teleported himself to the bed of golden flowers. (Sorry for the confusing time cut.)

He walked closer to the flowers, and saw that Flowey was facing away from him.

"Alright, weed. Whaddya want?" Sans asked impatiently.

Flowey was silent, but soon said, "I'm dying. Since I don't have a soul, I'm slowly deteriorating without one." Flowey explained.

Sans looked at Flowey expectantly. "And?"

"If I don't get soul in 7 days…I'll die." Flowey said, finally turning to face Sans.

"You think I care? The only reason I'd want you here is because the kid wants ya alive." Sans said.

"Exactly, so…" Flowey reached a green, root-like vine toward Sans. "I'm going to need your soul."

"Whoa!" Sans stepped back. "Why would you need my soul?" Sans asked.

"I know your soul isn't in the best shape, and it's weaker. Any other monster soul would've been too much for me." Flowey grew more vines and wrapped them around Sans's wrists.

"H-hey! Back off!" Sans struggled to get free, but only managed to have the vines wrap tighter around his wrists. He also tried to summon a gaster blaster, but failed.

"Why aren't my powers working?!" Sans asked, now in full panic mode.

Flowey put on a big, creepy smile. "Because I'm the one in control now."

"Wha-ahh-auugghh!" Sans groaned in pain as Flowey slithered through his bones like a snake. Soon, none of Flowey could be seen, except for his head poking through Sans's right eye socket.

"I'll be in here." Flowey's head disappeared into Sans's head.

"Gonna have to get used to that…" Sans told himself.

"Oh! Hello Sans! What a pleasant surprise!"

Sans turned around to see Toriel standing in the doorway to the Ruins.

"Oh! Hey Tori." Sans said, taking a breath from Toriel's sudden voice.

"May I ask what you're doing?" Toriel asked.

"Just came by to see the flowers. You're doing a pretty good job keeping 'em alive." Sans said.

"Why thank you, Sans!" Toriel said. "I just baked some pie. Would you like some?"

"Why not? I could really use some of your pie right now." Sans said.

Toriel gave Sans a piece for himself, and an extra piece as well. "Would you please take this piece for Frisk?" Toriel asked.

"Will do!" Sans said. "See ya!"

"Goodbye Sans."

With that, Sans teleported to his house. Then, Flowey popped his head through Sans's eye socket.

"Alright, bonehead. Make sure no one sees us." Flowey reminded Sans.

"No, duh. And you're calling me a bonehead." Sans remarked.

Flowey retreated back into Sans's head as Sans opened the door.

"You're back!" Frisk said.

"Yup. Also, I dropped by your mom's place and she gave us some pie." Sans set the piece of pie on a table near Frisk.

"Yes!" Frisk exclaimed.

While Frisk was eating, Sans was in his room, talking to Flowey.

"So…the deal with you is that you're staying in my body forever?" Sans asked.

"No. If I can't find a soul to possess in seven days…I'll die." Flowey said. "But, if I can't find soul in seven days, and I'm still in your body, you'll die as well."

"That doesn't make sense…" Sans contemplated what Flowey just said.

"Hey, I'm not the one who made the rules." Flowey said.

"Sure sounds like you did." Sans tried to glare at Flowey with his one eye.

"Well, you think what you think." Flowey said, irritated by Sans.

Sans sighed. "This is going to be the longest week of my life."
