The argument comes from Frisk being
able to resurrect in case they die, and
they cannot reach their SAVE File (
as even said in their profile), but there is something which is still worth to mention.
As said already in the
Flowey's profile, he lacks a soul, and yet he still can LOAD back to the SAVE point when he dies, meaning that DETERMINATION can LOAD even if both soul and body are destroyed.
But how this related with Frisk? As said before, they cannot LOAD anymore in the Asriel fight, given that a Determination user,
when they encounter someone with greater DT, they cannot LOAD anymore. And not even
Asriel was able to LOAD anymore, as he was forced to make Frisk give up in order to gain control over time, meaning that both of them couldn't SAVE, LOAD or RESET during the fight. Meaning that Frisk was still using their DT, but instead of LOADing back to a previous SAVE point, they straight up just resurrect, refusing to die.
What do I mean with this? DETERMINATION shown already the ability to bring back from complete destruction of body and soul through LOADing, and in case a high DT user like Frisk cannot LOAD, they should be able to resurrect, even if soul and body are destroyed.
It's basically regeneration instead of using time manipulation, so if time manipulation can bring back from soul + body destruction, regeneration should be able to as well.
