Someone please explain?!?

I need an explanation asap. Was this this the Syr who Bell rejected at the very end? Is the real Syr somewhere else that we haven't found yet since their date?

Has she been the Syr who went on the date with him from the very beginning? If so then why would the Freya Familia try to kill her?

Was there no Syr in the first place and just her? If so then why try to kill her? Please someone enlighten me.
