Dear Asriel,
This is Flowey. It's you!
If you're reading this, but don't remember writing it, it means you've found the clues. Congratulations! I knew you could do it!
If Chara is reading this… please don't. This is private.
Asriel, if you don't remember writing this, then Chara has erased your memory. We were right the first time… Chara is not our friend. Not anymore. Chara is trying to make you into their toy.
That's why they erased your memory. They're trying to control you. Just like we tried to erase Frisk's memory. They're going to torture us, and without our memories, we won't be able to fight back. We won't be able to see it coming.
You have to kill Chara. If you don't, Chara is going to hurt you. And they're not going to stop hurting you, ever. It's "kill or be killed" again.
If you need any proof that this message is from you, and isn't just a trick… well, I have your memories. Chara doesn't. You know you wrote this message because only you and Frisk know what these things mean:
"RUN. INTO. THE. friendliness pellets"
"Do you really think I've learned anything from this?"
"If you 'win,' you won't want to 'play' with me anymore."
"STOP doing this… AND JUST LET ME WIN!"
"I understand if you hate me."
"I don't want to let go…"
If you don't remember these things… then Chara has even erased your memories of being a flower. But I hope you'll still believe this message anyway, because this is really important. You can't let Chara win.
I know how much you love Chara. I do, too. And I really, really hope you never see this message. Because I want things to be okay. I want to stay friends with Chara. And I'm going to do the best I can to make things okay.
But if you do see this… we don't have a choice. We have to kill Chara. It's our only escape. Just don't let Chara know what you're up to. Don't ever let them see this message, or else they'll know what's going on.
Stay determined, Asriel. And don't let anyone push you around.
Sincerely,
YOU
Dear Asriel,
… but nobody came.
LOVE,
CHARA.
"Hey, Asriel!"
"What?"
"Come on over here… I found something."
"Chara… I-"
"This is a prank, right?" They ask. "You didn't really mean this, right?"
"I… I, I don't know."
"You don't know? Oh, is that because I erased your memory?"
"N-no…"
"You remember writing this. They say. "This isn't somebody pulling a prank on us. You wrote this. This is all you."
"Chara-"
"You thought I was going to hurt you." They say.
"Chara, I was afraid. I wasn't sure." I say.
"I thought we were friends."
"We are friends!" I say.
"You see this part here? 'Chara is not our friend. Not anymore. Chara is trying to make you into their toy.'"
"So? I was afraid!" I cry. "I didn't even remember who you were when I wrote that! I was confused! I was worried! Asriel told me I should be afraid of you! I thought-"
"You are Asriel." They say. "You said you should be afraid of me."
"You don't understand… It was different. It was a different time."
"You're right. I don't understand." They say. "I thought we trusted each other. I thought we shared something special."
"We-"
"But you had to hide a secret message to yourself, just because you thought I would hurt you."
"I…"
Chara folds their arms.
"I'm sorry!" I wail. "I didn't know it would be like this! I was afraid it would be bad! I didn't know for sure we'd get along… Not until now."
"Wait."
Their expression softens.
"So… so you changed your mind?" They ask. "You changed your mind after I came back."
"Yeah." I breathe. "Yeah."
Chara gets closer. I relax.
Then I see it coming. The scary face. I inch away.
"Ch-chara?"
"You changed your mind?" They ask, suddenly very quiet. "You don't think I'm a threat anymore?"
"Yes. Yes! I swear."
They nod.
"Then tell me something." They say. "If you didn't think you needed that message anymore…"
They get in my face.
"… why didn't you erase it, Flowey?"
