hi, thanks. the dark mother ending is only if you don't want to choose hannah or jezebel. if the dark mother is already unlocked with money there is no other reason. the thing is that "she is my favourite character" gets said a lot to me about pretty much every character in the game, and there are a lot of characters. not every character can have an ending. we will see what happens in the future. willpower needs to be kept high but with the right perk on your favourite working space it never becomes an issue. but if it runs too low you won't be able to work anymore
