I take it Rachel became the next siren at the end??

I take it by us seeing rachel at the end in Silkas clothes means she took her place and is the next Siren.... was that how silka became one??.

Also seeing as we see Silka screaming and soaked in blood in the film maybe a flash back to her before she became siren??.....

Sooo that is what happens it keeps going and going whoever defeats Siren becomes the next siren...

I really did not like this film really.
