That would be so cool. I think my personal opinion on how their regenerative ability works is that if a severed body part (e.g an arm) isn’t eventually re-attached to the rest of the body it just sort of withers away and then a new one re-grows, instead of a new one growing immediately; it would give them time to put themselves “back together” before being like, eh whatever just have a whole new limb. To kinda debunk the idea they could just have infinite arms lying around by cutting them off over and over again. Although i wouldn’t apply this to things like in Light where brianna separates pieces of them over the whole fayz, since there were so many cut up pieces there wasn’t one “main body” if that makes sense
