I'm confused...what was the test about?

i guess it was something about being told to fight the water.
but since she dint do what she was told. she dint blindly accept the conditions of the test. she instead accepts the water. it would make sense since your trying to contract the spirit instead of fighting it.
it makes more sense if someone explains it better than me lol
I'm so sad the brother died but then again I also know that he couldn't have survived in that household without turning out to be messed up too T_T
A little spoiler, he will be back as a doll, like undead.
