She uses music to help ease his tinnitus, caused by the attempted drowning.

Porter turns out to be a musical savant.

Present:

Porter continues to utilize music hoping to play for a large audience.

He captures women and uses their hair to string his violin bow before drowning them, echoing his own past.

Emerson and Rebecca capture him before he can attempt suicide.
