Story arc with a particular woman?

[PerfectBlue]

Right, I think killing the girl when Daniel questions what he has been doing blindly all along, and I believe this is when he decides to drink the Amnesia potion.

But the problem is they only played the girls scream ONE time to my knowledge. This should be something that HAUNTS Daniel the whole time, and he hears throughout his journey through the castle, and as I recall this wasn't so. For such a crucial plot element I think there are some missed opportunities.
