Could it be that Sans, Papyrus, and Undyne all had Determination inside of them? Undyne was able to fully utilize her Determination and turn into Undyne the Undying, while still be able to create spears. My theory is that, monsters with the ability to control Determination will be different, like Undyne with the ability to create spears, Papyrus with weak gravitokinesis, and Sans with mastered gravitokinesis. Undyne however, overloaded her Determination and evolved, than melted due to unbearable amount of Determination. This explains how the Sans/Papyrus brothers, normal civilians, can have a relationship with Undyne, who literally is obsessed with killing humans, and also doesn't care about anything else (Except a lizard.) This also explains Sans connection with Alphys, they could have been research partners in timelines (along with someone), and due to one of the failures that happened to their research (human souls in other dimensions may or may not be included), Sans gained his abilities, and later on affected Papyrus, giving him a small proportion of the power (And someone got banished into somewhere between the cracks of time and space.) About Undyne, she may already have the Determination inside of her, which is the Determination of hunting down humans (and the Determination of de-terminating monsters :) )

It's only theory, plz don't be mad if I'm wrong.

Also plz stop the grammar nazis, English is not my first language
