Fengo's decision was quite good for most people.
Ruth's Aislin didn't need to worry about how to hide her presence... because of Fengo's sudden move to drag the neutral faction into the water seemed a bit odd, Glaysia's attention noticeably shifted from her.
Otherwise, that bored Princess of Hell would have been observing how her soul might develop in another world, in another environment.
When Rosero advised 'Aislin' to live as she had in the past, his tone was strange, so 'Aislin' quickly realized Glaysia's true intention and deeply felt her mind was not quite right.
If she really has that kind of thought, then don't wake her real soul!
Let Aislin herself stir things around; wouldn't Glaysia be able to observe more clearly?
But 'Aislin' had to admit: this was indeed something she herself could do.
Glaysia is forever the most selfish.
