[RED ANON] We brought back the first fallen human, Chara. The both of them departed because of the nature of us anons, torment and cruelty. It was.. a nice moment for them to say the least, though all of our doings must be undone. You happen to reload at the same time we reset, thus Flowey remembers, at least some of it. Such a shame too! It would have been best if he could just forget it all so we can do it all over again.. Heh. Surely you agree with us, right?

[RED ANON] They were so fun to watch, Frisky! Watching Chara's temper-tantrums and Flowey's gullible mind, fooled by their tricks. It was amusing. But it's strange, Frisk. Why do you even bother keeping him around? You never listen to his wishes and all you brought him is suffering. Do you know? Do you know what's going on? Nope, because you don't even care~! You didn't even bother giving him a new pot or taking him to see the stars. 

[RED ANON] I doubt this was your first run. How many times, Frisk? Be honest. You don't care. Like it was said before, Flowey's only your game.
