Uh… did I just cause Old man Ueda to constantly remember his grand daughter?

So there is this side mission where you have to clear out a phantom from a supposedly cursed orphanage. The first time I did it, the phantom went feral and I had to kill it… the name of the phantom was the name of ueda’s grand daughter. So on my ng+2 I had an idea, I was thinking of instead of killing the phantom I decided to play the music box I got from Ueda… boy was I pleasantly surprised when the phantom reacted. Said a whole slew of dialogue. Something about not being lost and remembering where she lived and who she is. At this point she’ll not go red and attack you… IF you go back to the Ueda house, and talk to the old man he will say he heard the song that his granddaughter used to sing. And I just replied that she is a phantom trapped in between worlds…
