After they both got locked up in a room, Monika looked at Flowey, who was looking down.
"So... who's Asriel?" Monika asked, breaking the silence.
Flowey scowled, "Nobody important."
"... I see. He was the prince. He died because of his human sibling called Chara," Monika smiled.
Flowey glared at her, "How did you figure that out?"
'It's not like she read my thoughts... right? Right? I'm not going more crazy than I already am, right? My secret is still safe? Well... I guess not, since Sans knows...' He thought to himself.
She giggled, "You're not going more crazy, it's not safe, and I know too."
"How did you read my thoughts?!" He growled.
She snickered, "Admin privileges. As President of the Literature Club, I can see everyone's files, can edit anything I want about them, and read their thoughts."
"... Does that mean you know who actually killed Frisk?" He asked, curiously.
She sighed, "No... Remember, our games only crossed paths after they died."
"... Could you actually change my emotions?!" He asked, excitedly.
She nodded, "Yes."
"Okay... Can you let me actually feel something?!" He asked, smiling.
She sighed, "I see. You want Frisk's soul."
"Yes..." He sighed.
She snickered, "I can get you a soul, easily. In exchange for information about your timeline."
"... Fine," He grumbled.
She glared at him, "Don't get so grumpy with me."
"I don't have a soul. It's not my fault," He sighed.
She nodded, "Alright. Anyway, tell me everything you know about your game."
So he did. He explained everything that had happened when Asriel was alive, the war before that, and what happened with the flower, and what happened up until Frisk got killed.
"I see. Interesting. Anyway, as I promised..." She grinned, making seven souls appear around her.
He grabbed them, watching them circle around him.
There was a light, and then she gulped.
"It... actually worked. I didn't think it would actually work!"
