dark water returns

If that is the case, that she is possesses there is a simple solution. REMOVE THE UNWANTED SOUL. I really is that that complicated it is a simple 'exorcism' and I have done it countless times. If she is not possessed there will be no effect on her if she is then it will be removed. Simple as that.

but there may be a complication and it could rip her soul out with it like mine tried to do

well i skipped some of the stuff posted here but there is one way and then another way but the first idea might work but the second.............
