Actually, wasn't there a thing about Alphys injecting (Determination) into a yellow flower that had been connected somehow with Asriel?

But even then, that would just be Determination. That's only the ability to SAVE, LOAD, etc. Frisk and Chara can't use similar attacks to Flowey or other monsters, even if they have a soul.

Technically, by that kind of logic, Flowey shouldn't really have the ability to use bullets. Maybe lash out with some sort of knife, sure, but... We don't know what it is that grants access to magic. We only know that it exists, and that monster bodies are composed of magic and humans were once able to wield magic. So there's no real reason to limit the use of magic to beings with a soul. Nothing in the game states that a being needs a soul in order to access magic.

Also, yes, one of the True Lab entries states that Alphys began her experimentation with a vessel for determination by using the first yellow flower that grew in the garden, which would have contained some of Asriel's dust.
