Faust: Actually, if Faust relishes the joy of obtaining new data from someone/something that constantly regenerates no matter what horrific experiments she puts them through, then we should totally go with the third option! But one problem is definitely going to be the corpse lol. One way out is to have the experiment run away and never be found again considering how difficult tech was back then, I guess?

I imagine he'd have had powers back then too, so being a simple guy probably wouldn't have worked. The auxiliary powers (aka not the regen) would have singled him out as weird back then lmao. It's why I thought of the vampire bit, and a few pointers from past!Jack + his knowledge would have helped Faust out a bit on her way to immortality?

So far I'm inclined to go first or third :j
