So what if the resets where like like the hocu-something and frisk was like a which/Wizard but didn't know and Chara had placed the hourocucse(?)- thing when they fell and that's why frisks Determination can "wake" chara because of the sst (soul split thing) they (Chara) didn't die completely and Chara could be a Descendants/ancestor of Voldemort and that's why they could put the sst when they fell and frisks unknown magic increased the sst's power so that only the people without a soul or an equivalent amount of magic or slightly lower though the couldn't remember everything (since asgore can remember the Loads but not the resets[i think I may be wrong like about the whole sst thing too]) and flowey could do the resets because of the magic that he absorbed when Al but the determination on the flower that had his dust on it.
This is wrong it's not even a theory it's more like a crossover starter to be honest and I mean no offense
